asset.css¶

ViewHelper to add CSS to the TYPO3 AssetCollector. Either a file or inline CSS can be added.

Examples¶

<f:asset.css identifier="identifier123" href="EXT:my_ext/Resources/Public/Css/foo.css" />
<f:asset.css identifier="identifier123">
   .foo { color: black; }
</f:asset.css>

Details¶

In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if assets are added multiple times using the same identifier, the asset will only be served once (the last added overrides previous assets).

Some available attributes are defaults but do not make sense for this ViewHelper. Relevant attributes specific for this ViewHelper are: as, crossorigin, disabled, href, hreflang, importance, integrity, media, referrerpolicy, sizes, type, nonce.
