14The syntax for the new Bootstrap 4.5 utility classes is {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.
15The size values are:
161: 0.25rem
172: 0.5rem
183: 1rem
194: 1.5rem
205: 2rem
216: 3rem
22
23In Bootstrap 4alpa a spacing utility class '.m-l-1' would mean margin-left 1rem. With the new spacing classes it should now be '.ml-3'
24
25These class names have changed:
26.row-fluid is now .row
27.text-error is now .text-danger
28
29These classes should no longer be used:
30.label .label-{type}, use .badge .badge-{type} instead
31.tag .tag-{type}, use .badge .badge-{type} instead
32.well, just set a border with .border and a background with .bg-light

37* A function to core_renderer has been added, secure_layout_login_info. This allows the boost and classic templates to
38 display the users full name in a secure layout.
39* Secure layout in themes boost and classic have been modified to allow language selection as they now call the
40 output.secure_layout_language_menu function.

44* Moodle does not produce chunked CSS anymore, instead an unique css fils is generated and served (MDL-55751). This implies:
45 * css_chunk_by_selector_count() has been removed.
46 * css_store_css(), theme_styles_get_filename() and theme_styles_get_etag() don't accept any chunk-related param anymore.
cddcfccc
MM
47* The PHP Less compilier has now been removed from the core library.
48 Please consider migrating your theme to use SCSS.

AN
49* It is now possible to use sub-directories when creating mustache templates.
50 The standard rules for Level 2 namespaces also apply to templates.
51 The sub-directory used must be either an valid component, or placed inside a 'local' directory to ensure that it does not conflict with other components.
52
53 The following are all valid template names and locations in your theme:
6097e14b
GB
54 theme_themename/columns2: theme/[themename]/templates/columns2.mustache
55 theme_themename/local/layouts/columns2: theme/[themename]/templates/local/layouts/columns2.mustache
0261d1ef
AN
56
57 The following are core templates, locations, and override locations in your theme:
6097e14b
GB
58 core/modal: lib/templates/modal.mustache => theme/[themename]/templates/core/modal.mustache
59 mod_forum/forum_post: mod/forum/templates/forum_post.mustache => theme/[themename]/templates/mod_forum/forum_post.mustache
60 mod_forum/local/post/user: mod/forum/templates/local/post/user.mustache => theme/[themename]/templates/mod_forum/local/post/user.mustache

1baadc87
MM
67* Boost theme renderer overrides have now been migrated to core.
68* Renderers that were overridden by Boost are now in Bootstrapbase
69* Core templates in Boost have now moved into core
70* Templates that were overridden by boost are now located in Bootstrapbase

BB
75* A new callback has been added to the theme layout files allowing plugins to inject their content
76 into the page. For Boost it was added as a mustache variable "{{{ output.standard_after_main_region_html }}}" in
77 templates/columns1.mustache and templates/columns2.mustache. In bootstrapbase it was added as a
78 function call "$OUTPUT->standard_after_main_region_html()" in layout/columns1.php, layout/columns2.php.
79 and layout/columns3.php. Child themes not inheriting these templates should add the function call
80 after the div containing the main content region. Please refer to the messaging drawer UI for an example of
81 making use of this new feature.
a266ae30
TH
82* The body tag has various browser-specific classes for those cases where some
83 browser-sniffing is unavoidable. This used not to recognised Microsoft Edge,
84 but now it does (class 'edge'). Also, both Safari and Chrome used to be
85 class 'safari', but now there are separate classes 'safari' and 'chrome'.
86 The body's class should change to match the browser:
87 - Google Chrome (Mac & Window): The body class should change from safari to chrome.
88 - Google Chrome (Android) : The body class should change from safari, android to chrome, android.
89 - Microsoft Edge: The body class should change from safari to edge.
90 - Mobile safari: The class ios should exist, safari class should be removed.
91* Remove class .safari styling from activity chooser dialog for theme boost and bootstrapbase.
216b8947
MG
92* The following functions and classes have been finally deprecated and can not be used anymore:
93 * css_is_colour()
94 * css_is_width()
95 * css_sort_by_count()
db03bff7 96 * core_course_renderer::add_modchoosertoggle()
216b8947 97 * class css_optimiser

101* There was a mustache template login.mustache in /lib/templates/ rendering the login form
102 and a template with the same name in /theme/boost/templates/ rendering the pagelayout "login".
103 To prevent misunderstanding when overriding one of these templates in a Boost child theme,
104 the first one was renamed to loginform.mustache - see MDL-58970.
d7d2a72f
AB
105* The Boost flat navigation nodes now have several data-attributes which let plugin developers
106 access properties from the underlying navigation nodes in the browser - see MDL-59425.
d8cb4615
MN
107* Navigation between activities via a previous and next link was added to Boost, Clean and Bootstrapbase. This
108 is made possible by a new function core_renderer->activity_navigation().
4a8dfef0
JB
109* Theme designers may now place the Reset tour on this page link where required by adding an empty
110 container (e.g. <div class="tool_usertours-resettourcontainer"></div>) to their layouts.
46676b76 111

DP
112=== 3.3 ===
113
114* As boost-based themes no longer use the moodle-core-popuphelp help popups, the javascript
115 setup for this module have been moved from core standard_head_html to the bootstrapbase
116 renderer. If your theme needs this javascript you will need to ensure the bootstrap renderer
117 is called, or require the JS yourself
118

119=== 3.2 ===

862816ee
FM
121* Removed themes: base, canvas
122 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
123 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
124 the theme/ directory BEFORE UPGRADING.
2ede86d7 125* Bootstrap 4 was added as part of a the new theme 'boost'.
862816ee
FM
126* Some backwards and forwards compatibility has been added for different bootstrap versions.
127 This is to allow the same markup to work in "clean" and "boost" themes a lot of the time.
128 It is also to allow user text with bootstrap classes to keep working in the new theme.
d3c35f93
FM
129* Using .dir-rtl for RTL styling is deprecated and should not be used any more. From now
130 the styles are automatically flipped when the language is right-to-left. However,
131 as this is not always perfect, you can define exceptions. Please refer to the documentation
132 of the tool RTLCSS-PHP for more information: https://github.com/moodlehq/rtlcss-php
862816ee
FM
133* Themes can now automatically compile SCSS on the fly. This works the same way as it
134 does compiling LESS on the fly, effecitvely adding $THEME->scss to your config. The
135 latter can either be the name a SCSS file (without extension) in your theme's scss/ folder,
136 or a Closure which will return the main SCSS content.
137* Two new callbacks allow themes to inject SCSS code before and after the content provided
138 by the SCSS file $THEME->scss. See $THEME->prescsscallback and $THEME->extrascsscallback.
139* A new callback can be defined to post process the CSS using an object representation
140 of the CSS tree ($THEME->csstreepostprocess). This gives a lot more flexibility than a
141 simple find and replace. Refer to 'boost' for an example, and to PHP-CSS-Parser.
142 (https://github.com/sabberworm/PHP-CSS-Parser) for the API.
143* A new core setting now enables admins to upload the logos of their site. Using the
144 following methods, themers can instantly support branding logos without the need
145 to implement specific theme settings:
146 * $OUTPUT->get_logo_url($maxwidth, $maxheight);
147 * $OUTPUT->get_compact_logo_url($maxwidth, $maxheight);
d3c35f93
FM
148* The class .dir-ltr should not be used any more. To force LTR styles use the directive
149 to remove the rule when the language is RTL. See RTLCSS-PHP for more information.
113efed5
FM
150* A new class .text-ltr may be used to force the direction to LTR. This is especially useful
151 for forms fields (numbers, emails, URLs must not be RTL'd), and for displaying code
152 snippets or configuration samples.
9d1402ab 153* A new theme config 'requiredblocks' allows a theme to define which blocks are deletable.
4f2378d9
FM
154* You may no longer override the following core_course_renderer methods.
155 See course/upgrade.txt for more information:
156 - course_modchooser_module_types
157 - course_modchooser_module
158 - course_modchooser_title
891750bc
FM
159* The question chooser now uses a renderable and a template, the following methods
160 have been deprecated in favour of core_question_bank_renderer::render_qbank_chooser().
161 - qbank_chooser
162 - qbank_chooser_types
163 - qbank_chooser_qtype
164 - qbank_chooser_title
d52ebf11
DP
165* The 'css optimiser' has been removed. Developers are encouraged to use tools such as stylelint
166 to help optimise their css. Some functions and classes in lib/csslib.php (which was not for public use)
167 have been deprecated:
168 - css_is_colour
169 - css_is_width
170 - css_sort_by_count
171 - class css_optimiser no longer does anything.
862816ee
FM
172* CLI svgtool.php has moved from theme/base/cli to admin/cli and paths should be relative to the new location.
173* mod_chat will now display the 'course theme' option for all themes (previously it was only displayed on
174 bootstrap2 based themes).
b11916d3
MG
175* Theme can choose how to display "Add a block" control in $THEME->addblockposition, default value is
176 BLOCK_ADDBLOCK_POSITION_DEFAULT that displays it as a fake block in editing mode.
2258b4dc 177
4040c8b3
DM
178=== 3.1 ===
179
180* A new search box for global search has been added to bootstrap and clean layout files, if
181 your theme is overwriting columns1.php, columns2.php or columns3.php you will need to add a
182 call to core_renderer::search_box to display it.
24346803
AN
183* Notification templates have been renamed to better suit types of alert
184 rather than uses. The following changes have been made:
185 * notification_problem.mustache => notification_error.mustache
186 * notification_message => notification_info
187 * notification_redirect => notification_warning
f59f89b4
MG
188* Method core_course_renderer::course_section_cm_name() is split into two methods, custom themes that override
189 this method must be modified or otherwise editing functionality may become broken. This method is now also used by
190 social activities block and site menu block to display activities names.
4040c8b3 191
c7b73854 192=== 3.0 ===
193
194* The renderer function core_availability_renderer::multiple_messages was changed to
195 render_core_availability_multiple_messages, requiring a parameter of the new
196 \core_availability\multiple_messages type.
5e9a937b
JO
197* Meta description is now included in standard_head_html for homepage in bootstrapbase.
198 If your theme includes a meta description directly in a layout for the frontpage,
199 you will need to remove it or override the standard_head_html instead.
45cd3f60
DM
200* Themes Clean and More have been updated to use a new navbar_button function, which shows the
201 hamburguer icon (responsive menu) or not depending on custom and language menus settings;
202 themes extending bootstrapbase and overriding its layouts can call replace their "a.btn-navbar"
203 node for a call to this function.
c47f3803 204* Themes Clean and More page header logo only displays on front page and login page.
c08b52aa
DM
205* A new function navbar_home has been added to theme_clean and theme_more to display the navigation bar link
206 to the site home. Two new settings have been added to control if the link should be a small logo image, text
207 or both. It defaults to the current behaviour, only a text link.

211* Themes Bootstrapbase, Clean and More have undergone some changes for RTL layouts see - MDL-48160.
212
c58891f1 213* Themes Clean amd More page header background logo, if loaded, no longer links to the home page.
c36c3d07
AG
214* Themes Clean and More have been updated to use the renderer full_header(). This renderer (when in a user context) displays a message button
215 and consequently the link to message users have been removed from various pages. It is recommended that theme developers use this
216 renderer to ensure that they do not suffer from a reduction in access to this feature.
217* $OUTPUT->context_header() has been introduced to produce headers similar to what full_header() creates. This renderer is used for creating
218 subsequent headers in a page. If provided with user information, this render will also display a message button like full_header().
c58891f1 219
c10fa5da 220=== 2.8 ===
c58891f1 221
a2633964
ME
222* Themes Base and Canvas layout/embedded.php has changed.
223 The div id="content" has been changed to id="page-content" - see MDL-47915.
c10fa5da
DW
224* All mod_assign CSS selectors have been qualified with ".path-mod-assign". This means any custom CSS
225 rules for mod_assign in a theme may need to be updated.
ebdcb292
SH
226* The following render methods were renamed, if you have overridden any of these you will need to update your renderer:
227 - report_log_renderer::render_report_log_renderable => report_log_renderer::render_report_log
228 - report_loglive_renderer::render_report_loglive_renderable => report_loglive_renderer::render_report_log
a2a4ad89 229* On calendar view screen the course selector and new event button have been swapped, custom CSS for .path-calendar might be affected.
2f6a0e5f
MN
230* The functions search_listing() and search_pagination() in the core_course_management_renderer class take the searched string
231 as an extra parameter - see MDL-46902.
f2b4b2ad 232* Themes with non-fixed headers must have the .navbar class in their navbar in order for floating headers in the grader report to work - see MDL-46658.
6d8eba1a
JC
233* To accomodate the new gradebook, use of overflow: hidden or overflow-x: hidden CSS rules on DOM elements containing the
234 #user-grades table, visible at [Course administration -> Grades] is not recommended. Please use overflow: auto or
235 overflow: scroll instead, as this will handle medium to large courses with multiple activities better (more information available at https://docs.moodle.org/dev/Theme_upgrade_notes ).
236* The new user menu can be added to themes by calling $OUTPUT->user_menu(); we recommend doing so in a backwards-compatible way (see https://docs.moodle.org/dev/Theme_upgrade_notes for more information).
c10fa5da 237

238=== 2.7 ===
239
31f28b6a
240* CSS related functions in theme class and csslib.php were refactored, addons that are
241 using this private API need to be updated
ba55be91 242* Please update your css to use 'tr:nth-of-type(odd/even)' instead of '.r0/.r1' to apply tr specific css for various tables.
98396c23
SH
243 These classes are deprecated now and will be removed in Moodle 2.9. This has done to better support styling tables that will be altered by JavaScript.
244 Here is an example to update your css:
245 Old code:
246 table.generaltable .r0 {background-color: #F0F0F0;}
247 table.generaltable .r1 {background-color: #F0F0F0;}
248 New code:
98396c23 249 table.generaltable > tbody > tr:nth-of-type(even) {background-color: #F0F0F0;}
ba55be91 250 table.generaltable > tbody > tr:nth-of-type(odd) {background-color: #F0F0F0;}
6b216432 251

FM
252Removed themes:
253* afterburner, anomaly, arialist, binarius, boxxie, brick, formal_white, formfactor, fusion, leatherbound,
254 magazine, nimble, nonzero, overlay, serenity, sky_high, splash, standard and standardold have been removed.
255 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
256 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
257 the theme/ directory BEFORE UPGRADING.
6b216432 258
71715870
JC
259Notes:
260* z-index on #dock has been adjusted from 11000 to 5000 to prevent overlapping issues with fullscreen TinyMCE in Base theme.
261
699e2fd0 262=== 2.6 ===
3b42864d 263
7c2efc11
JM
264Removed themes:
265* "My Mobile" theme has been removed (see MDL-40874).
266 During the upgrade process "My Mobile" theme will be uninstalled and all its settings will be deleted.
267 "My Mobile" theme and its extending themes will fallback to the mobile friendly "Clean" theme.
268 If you wish to keep "My Mobile" theme and its settings, BEFORE UPGRADING you can copy the files from the
269 unmaintained plugin into theme/mymobile.
270 The unmaintained plugin can be downloaded at https://moodle.org/plugins/pluginversion.php?id=4563
699e2fd0 271Notes:
faf6010b 272* There have been several changes made to the classes used on headings throughout Moodle.
273 This was done as per the Moodle HTML guidelines. h1 and h2 elements should have no classes, h3 and lower headings
274 may have descriptive classes only (any classes must properly describe the relation between the header and its content).
699e2fd0 275* The parameters value for the following functions have been modified: core_renderer::heading() and core_renderer::heading_with_help().
3b42864d 276 This means that headings using the default options will no longer have the class "main" which was the previous default.
d61c96b6 277* The file picker and activity chooser have been converted to use M.core.dialogue. This means the styles
3b42864d
RW
278 for these elements have changed in the base and bootstrapbase themes and you will need to copy the new styles
279 if you are not inheriting from either one of these themes.
b4c6b42e 280* For the themes based on bootstrapbase please also read theme/bootstrapbase/upgrade.txt
e5de4933
SH
281* A new component action_menu is now used to display editing icons for courses and blocks within a drop down. If you have a theme that doesn't
282 extend base, canvas, or clean then you will need to style for this new component within your theme.
166ac0a3
SH
283* The maintenance layout now has a special renderer that extends the core_renderer in order to prevent some methods from interacting
284 with the database. Please be aware that for the maintenance layout some methods now always return an empty string.
285 This has been done because it is important that during maintenance routines we don't show any links, interact with the database,
286 or interact with caches as doing so may lead to errors,
287 Please see the maintenance renderer notes below for details on the functions affected.
e5de4933
SH
288
289Renderer changes:
290* core_course_renderer::course_section_cm_edit_actions has two new optional arguments and now uses and action_menu component.
291* core_course_renderer::course_section_cm has been altered to call core_course_renderer::course_section_cm_edit_actions with the two new arguments.
292* core_renderer::block_controls has a new optional argument (the block id) and has been altered to use the new action_menu component.
293* core_renderer::block_header has been altered to give core_renderer::block_controls the new second argument, the block id.
294* core_renderer::action_link has a new argument, and optional icon that can be rendererd into the link.
295
faf6010b 296Selector changes:
297* Changes to the classes given to the header produced when rendering a single section within a course.
298 .section-navigation.header.headingblock => .section-navigation.navigationtitle
299* Changes to the classes used when producing the course information box that lists courses.
300 The name (h3|div} of both courses and categories used to have .name, for courses in the list this was changed to .coursename and for categories in the list this was changed to .categoryname.
301* Classes ".header and .headingblock" were removed from all front page content headings.
302* Classes ".headingblock .header .tag-header" were removed from the tag index page
303

304Maintenance renderer notes:
305When the maintenance layout is being used $OUTPUT will be an instance of core_renderer_maintenance.
306This renderer mimics the core_renderer except that the following functions always return an empty string.
cf9f5a17 307* core_renderer_maintenance::block
308* core_renderer_maintenance::blocks
309* core_renderer_maintenance::blocks_for_regions
310* core_renderer_maintenance::course_header
311* core_renderer_maintenance::course_footer
312* core_renderer_maintenance::course_content_header
313* core_renderer_maintenance::course_content_footer
314* core_renderer_maintenance::custom_menu
315* core_renderer_maintenance::file_picker
316* core_renderer_maintenance::htmllize_file_tree
317* core_renderer_maintenance::lang_menu
318* core_renderer_maintenance::login_info
319* core_renderer_maintenance::user_picture
166ac0a3
SH
320
321If you have overridden methods of the core_renderer in your theme and want those changes to be shown during times of maintenance you
322will also need to override the core_renderer_maintenance and copy your customisations from the core_renderer to that.

SH
325
326Notes:
327* Block drag and drop functionality has been improved so that it works regardless of what block regions you use
328 or how many block regions you have. In order to benefit from this improvement you must convert your calls from
329 $OUTPUT->blocks_for_region() to $OUTPUT->blocks.
330
331Optional changes:
332* Theme config can nominate block regions to swap if the user is using a rtl languages such as Hebrew.
333 $THEME->blockrtlmanipulations should be an associative array, the key is the original block region, and the
334 value should be where the blocks in that region should be displayed.
335* New $OUTPUT methods to replace code that was previously using $PAGE. Converting to these methods is optional
336 but highly recommended. Refer to the bootstrapbase layouts for examples.
337 - $OUTPUT->body_attributes() returns a string you can use for the body id and classes.
338 - $OUTPUT->blocks() returns HTML to display a block region and all of its blocks. This adds data attributes
