I know script files can use the DEFER and ASYNC keywords on a resource include. Do these keywords also work for stylesheet (i.e., CSS) includes?
Syntax would presumably be:
<link rel="stylesheet" type="text/css" href="./path/to/style.css" defer />
I just don't know if it's allowed or not.
Defer
and Async
are specific attributes of the tag <script>

They will not work in other tags, because they don't exist there. A stylesheet is not a script that contains logic to be executed in parallel or after the loading. A stylesheet is a list of static styles that get applied atomically to html.
