Opis

Plugin’s purpose

• ✅ Your WordPress is of version 5.9 or newer

Technical info

WordPress 5.9 started applying !important rule and is setting up CSS properties (CSS variables) within body selector in its global styles code. This rises the global styles specificity and may override styles coming from themes and plugins. (For more info about this change check „Updates for Settings, Styles, and theme.json” article.)

Global Styles Mods plugin lowers the specificity of WordPress 5.9 global CSS styles by removing !important rules and changing body to :root selector for setting up WordPress CSS properties (CSS variables).

It also enqueues the global styles early enough so your theme or plugin stylesheet have a better chance to override global styles with minimal effort.

The fix applied is coming from issue conversation in Gutenberg GitHub repository.
