I’m trying to customize the look of my Notion pages by adding CSS classes to elements in the edit view. However, it seems Notion’s technology stack (maybe Flutter for web?) is preventing this from working as expected. The DOM tree appears to be controlled by a mutation state.
When I attempt to add a class to a Notion page element, I get this console warning:
NOTION WARNING Reverting mutation of attribute class from "notion-selectable notion-text-block" -> "notion-selectable notion-text-block" in component undefined MutationRecord
Does anyone know a way to successfully inject custom classes into Notion elements? I’m curious if there’s a workaround or if this is just not possible due to Notion’s architecture. Any insights or alternative approaches for styling Notion pages would be greatly appreciated!
Unfortunately, directly injecting custom CSS classes into Notion’s interface isn’t supported due to their architecture. The warning you encountered is part of Notion’s safeguard against modifications that could affect consistency and stability.
One possible solution is to use a browser extension such as Stylus, which lets you apply custom CSS externally without altering the DOM. Alternatively, leveraging Notion’s API to create a custom front-end can offer more styling flexibility. Tools like Super or Fruition also provide additional customization options while still using Notion’s backend.
I’ve been down this road before, and it’s a tricky one. Notion’s architecture is pretty locked down when it comes to direct DOM manipulation. I found a workaround that might help, though. Instead of trying to inject classes, I use the Stylus browser extension to apply custom CSS. It’s not perfect, but it gets the job done without triggering those pesky warnings.
Another approach I’ve had success with is using Notion’s API to build a custom front-end. It’s more work, but it gives you full control over the styling. If you’re comfortable with coding, it’s worth exploring. Just keep in mind that you’ll need to handle updates and maintenance yourself.
Ultimately, Notion’s limitations on custom styling are frustrating, but they’re there for a reason. It ensures consistency across devices and prevents potential conflicts. Sometimes, we just have to work within the constraints of the platform we choose.
hey noah, i feel ur pain. notion’s pretty stubborn bout custom css. have u tried the stylebot extension? it lets u tweak styles without touchin the DOM. might be worth a shot. another idea is usin notion’s API to build ur own frontend. more work, but total control. good luck mate!
