public AssetResolverInterface::getCssAssets(AttachedAssetsInterface $assets, $optimize)
Returns the CSS assets for the current response's libraries.
It returns the CSS assets in order, according to the SMACSS categories specified in the assets' weights:
This ensures proper cascading of styles so themes can easily override module styles through CSS selectors.
Themes may replace module-defined CSS files by adding a stylesheet with the same filename. For example, themes/bartik/system-menus.css would replace modules/system/system-menus.css. This allows themes to override complete CSS files, rather than specific selectors, when necessary.
Also invokes hook_css_alter(), to allow CSS assets to be altered.
Parameters
\Drupal\Core\Asset\AttachedAssetsInterface $assets: The assets attached to the current response.
bool $optimize: Whether to apply the CSS asset collection optimizer, to return an optimized CSS asset collection rather than an unoptimized one.
Return value
array A (possibly optimized) collection of CSS assets.
