scripting

Baseline 2023

Newly available

Since December 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

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.

none

Scripting is completely unavailable on the current document.

initial-only

Scripting is enabled during the initial page load, but not afterwards.
