HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as async.
The async
and defer
boolean attributes of the <script>
element control how an external script should be executed once it has been downloaded. The async
attribute makes sense when an external script (defined with the src
attribute) is loaded, or when defining a script of type module
:
<script async src="app.js"></script>
<script type="module">
/* JavaScript module code here */
</script>
