scripting - CSS | MDN
scripting Baseline 2023
Newly available
The scripting
CSS media feature can be used to test whether scripting (such as JavaScript) is available.
Note:
The detection is done by the browsers based on the user settings. Some browser extensions can implement script blocking using different techniques. In such cases the scripting
media feature may not work as expected.
The scripting
feature is specified as a keyword value chosen from the list below.
none
Scripting is completely unavailable on the current document.
initial-only
Scripting is enabled during the initial page load, but not afterwards.
enabled
Scripting is supported and active on the current document.
<p class="script-none">You do not have scripting available. :-(</p>
<p class="script-initial-only">
Your scripting is only enabled during the initial page load. Weird.
</p>
<p class="script-enabled">You have scripting enabled! :-)</p>
