Overriding styling

svelte-tabs comes with a basic default style, but it can be overridden. To override the styles to use your own, you will need to use global styles that have a higher specificity than the built-in styles.

To make sure your overridden styles have the most specificity, include the parent class .svelte-tabs in your selector, and include the element type (see below). An example selector would be :global(.svelte-tabs li.svelte-tabs__selected).

Below are CSS selectors that can be used for the different components in this library:

Tabs: :global(.svelte-tabs)
Tab: :global(.svelte-tabs li.svelte-tabs__tab)
Selected Tab: :global(.svelte-tabs li.svelte-tabs__selected)
TabPanel: :global(.svelte-tabs div.svelte-tabs__tab-panel)

As a last resort, if you can't get the right specificity, you can always use !important.
