• selectedTabIndex (number): The index of the tab to initially select, when the Tabs component is mounted.

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.

• Fork and clone the repository, then run npm install.
• From the repository root, run npm link.
• From the repository root, run npm run build:watch.
• From the examples directory, run npm link svelte-tabs.
• From the examples directory, run npm run dev.
• Go to http://localhost:5000.
• You now have a running development environment. Changes you make to the component will be reflected in the app.

To do a single run of the tests, run npm test. To run the tests in watch mode, run npm run dev:watch.
