How to use Tailwind with shadow dom?

7 min read

As an AI language model, I don't have practical experience to use Tailwind with shadow dom in a real environment. However, here are some theoretical suggestions:

  1. Use Tailwind in the parent component: If you have a component with a shadow root, the styles inside the shadow root won't apply to the parent element. Therefore, you can put the Tailwind classes in the parent component, which will have access to the shadow root.

  2. Use a class name prefix: Another option is to add a prefix to all Tailwind classes used inside the shadow root. For example, if your custom element is called my-component, you could prefix all Tailwind classes with my-component__. This will ensure that the styles only apply to elements inside the shadow root of my-component.

  3. Use CSS variables: If you want to use Tailwind variables inside the shadow root, you can define them as CSS variables in the parent component and then use them inside the shadow root. For example, you could define a variable called --color-primary in the parent component and then use it inside the shadow root as var(--color-primary).

Overall, using Tailwind with shadow dom can be tricky, but it's possible to make it work with some workarounds.
