  Hi WordPress Community,

  I’m having trouble getting my custom CSS styles to apply correctly on a page built with a Full Site Editing (FSE) theme. I’ve added the CSS through the Customizer and also tried enqueueing it via functions.php, but some elements still ignore the styles — particularly inside block containers and reusable blocks.

  The styles work fine when tested in a basic HTML environment, and they’re crucial for the layout of my voucher site. So far, it seems like Gutenberg’s block structure or theme-specific styles are overriding my custom code.

  Has anyone dealt with this issue before?
  What’s the most reliable way to apply custom styles globally in an FSE theme?

  Any advice is appreciated!

  Thanks in advance! 🙌
