How to Reveal a Page After A/B Test Changes Load

★★★ Technical level 3 of 3

Written by Neil Webley · Last updated

Remove test hiding CSS as soon as a variant is ready.

What you need to know

Place Reveal Page after the variant changes. It removes the test-specific CSS identifier created by Hide Page.

How to use it safely

Fail open when optional work errors. If elements load later, use polling plus a short safety timeout rather than hiding indefinitely.

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.
