★★★ Technical level 3 of 3

Written by Neil Webley · Last updated

Remove a named test stylesheet without disturbing site styles.

What you need to know

The identifier passed to removeCSS must exactly match the one used by addCSS. Never target a global site stylesheet.

How to use it safely

Use it to remove temporary highlighting or restore a component. Confirm only the intended style element disappears.

Before publishing

  • Use Staging to test control and every variant.
  • Check matching and non-matching locations.
  • Verify mobile, desktop, accessibility and analytics behaviour.
  • Ask someone else to review the setup.
