===============================================================
Feature: #100232 - Load additional stylesheets in TYPO3 backend
===============================================================

See :issue:`100232`

Description
===========

It is now possible to load additional CSS files for the TYPO3
backend interface via regular :php:`$TYPO3_CONF_VARS` settings in a
:file:`settings.php` file of a project (previously known as :file:`LocalConfiguration.php`)
file or in an extension's :file:`ext_localconf.php`.

Previously this was done via the outdated :php:`$TBE_STYLES`
global array which has been deprecated.


Impact
======

By defining a specific stylesheet, a single CSS file or all CSS files
of a folder, extension authors can now modify the styling via:

..  code-block:: php
    :caption: EXT:my_extension/ext_localconf.php

    $GLOBALS['TYPO3_CONF_VARS']['BE']['stylesheets'][my_extension]
        = 'EXT:myextension/Resources/Public/Css/myfile.css';

    $GLOBALS['TYPO3_CONF_VARS']['BE']['stylesheets'][my_extension]
        = 'EXT:myextension/Resources/Public/Css/';

in their extension's :file:`ext_localconf.php` file.

Site administrators can handle this in their :php:`settings.php` or :php:`additional.php` file.
