Twenty Twenty: Editor styles target the block toolbar, causing pixel shifting

Reported by: joen's profile Joen Owned by:
Milestone: Priority: normal
Severity: normal Version: 5.5
Component: Bundled Theme Keywords: has-screenshots close
Focuses: Cc:


Steps to reproduce:

  • Use a WordPress 5.5 build, or have the Gutenberg plugin activated
  • Use TwentyTwenty
  • Select a block in the block editor and hover the block type indicator with the mouse

Observe that the icon shifts a pixel up and down as you hover the icon.

This shift is caused by the following CSS in the editor style:


	.editor-styles-wrapper > * {
		font-size: 21px;

This CSS targets every element inside the editing canvas,including block UI such as the block toolbar.

First discovered in

The best fix is be to use the editor styles API for adding editor styles, outlined in In doing so, the following CSS would be plenty to set the baseline font size, without affecting block UI:

body {
	font-size: 21px;

However, it is my understanding that TwentyTwenty intentionally avoids doing so, for reasons outlined in this ticket:

Outside of using the editor styles API, it's possible there's a smaller or interim solution that just reduces the specificity of the selector, or avoids targetting the block toolbar.

I am no longer able to reproduce this (testing with WP 6.2, Chrome, Firefox), I suggest closing this ticket as fixed.

I also can't reproduce this @poena so I am going to agree with closing this as fixed. Thankyou everyone for collaborating on this. Should it still be an issue for anyone we can look to reopen if we have some steps to reproduce.
