-This file describes API changes in /theme/ilb
-information provided here is intended especially for theme designers.
-
-=== 3.6.2 ===
-
-Form element template
----------------------
-A 'wrapperid' has been added to 'templates/core_form/element-template.mustache' to restore unique ids
-on Ilb form element wrappers. This restores the same unique element ids seen on elements in BS2
-themes, which were mistakenly dropped when introducing the Ilb theme.
-
-=== 3.5 ===
-
-The Ilb theme now uses Bootstrap 4 Stable (BS4S).
-
-We are trying to use as much BS4S classes in MDL Templates to reduce the amount of Moodle CSS.
-
-The biggest changes are:
-
-JavaScript
-----------
-* All Bootstrap javascript has been updated.
-
-Sass
-----
-* A number of variables are no longer available in Bootstrap 4 Stable. For now a bs4alpha compatibility file has been added, see scss/bs4alphacompat.scss which translates veriable names from the Alpha version to the stable version.
-
-* m-t-* and other spacing utilities should be replaced with mt-*.
-
-The units that were used for margins have changed too
-m-t-1 is now mt-3
-m-t-2 is now mt-4
-m-t-3 is now mt-5
-
-
-Grid and Flexbox
-----------------
-The Ilbrap grid uses CSS's flexbox grid to build layouts.
-
-New breakpoints for grids have been added:
-.col-*  <576px
-.col-sm-* >= 576px
-.col-md-* >= 768px
-.col-lg-* >= 992px
-.col-xl-* >= 1200px
-
-All usage of '*-xs-*' have been dropped. So what used to be col-xs-6 should now be written as col-6.
-
-*-md-* has become *-lg-*, and *-lg-* has become *-xl-*.
-
-Typography
-----------
-Ilbrap 4 uses a native font stack that selects the best font-family for each OS and device. For font sizing the browser default root font-size (typically 16px) is used. this variable can be changed using the variable '$font-size-base'.
-In the default Ilb preset we use: "0.9375rem" which computes to 15px on most browser.
-
-Presets
--------
-The structure of preset files have changed. The new structure of a preset file is:
-
-// Space to set variables.
-$font-size-base: 0.9375rem
-
-// Import FontAwesome.
-@import "fontawesome";
-
-// Import All of Bootstrap.
-@import "bootstrap";
-
-// Import Core moodle CSS.
-@import "moodle";
-
-// Space to use Bootstrap mixins and extends.
-.navbar {
-  @include shadow();
-}
-
-Bootswatches
-------------
-Bootstrap 4 bootswatches can be imported using the theme/ilb/cli/import-bootswatch.php script. Generated bootswatches can be added in the theme ilb settings page.
-
-Changed Components
-------------------
-Cards need this structure
- class='card'
-    class='card-body'
-This used to be 'card-block'
-
-The header.mustache template has been replace by a navbar.mustache template for name consistancy with Bootstrap
-
-A new header.mustache template has been created served from core/core_renderer.php. This should be move to core at some point.
-
-
-=== 3.4 ===
-* For improved accessibility, the footer links for ilb have been changed to use $bg-inverse-link-color (defaults to white) and
-  now have an underline text-decoration. To override the link colour simply set $bg-inverse-link-color in your preset file or
-  theme scss.
-* To match the new primary colour we are switching to using the UX pallette, which uses a purple colour for info. To override,
-  set $brand-info in your preset file or theme scss.
