`scripting` CSS media feature

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.

Syntax

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.

Examples

HTML

<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>

CSS

p {
  color: lightgray;
}

@media (scripting: none) {
  .script-none {
    color: red;
  }
}

@media (scripting: initial-only) {
  .script-initial-only {
    color: red;
  }
}

@media (scripting: enabled) {
  .script-enabled {
    color: red;
  }
}
