+A great way to use icons is to define them purely via CSS. Iconify offers support for [many popular icon sets](https://icon-sets.iconify.design/) that [can be included via CSS](https://iconify.design/docs/usage/css/). This method can also be used with popular CSS frameworks by leveraging the Iconify [Tailwind CSS plugin](https://iconify.design/docs/usage/css/tailwind/) or [UnoCSS plugin](https://iconify.design/docs/usage/css/unocss/). As opposed to libraries based on Svelte components, it doesn't require each icon to be imported into your `.svelte` file.

+## Svelte
+
+There are many [icon libraries for Svelte](https://www.sveltesociety.dev/packages?category=icons). When choosing an icon library, it is recommended to avoid those that provide a `.svelte` file per icon as these libraries can have thousands of `.svelte` files which really slow down [Vite's dependency optimization](https://vite.dev/guide/dep-pre-bundling.html). This can become especially pathological if the icons are imported both via an umbrella import and subpath import [as described in the `vite-plugin-svelte` FAQ](https://github.com/sveltejs/vite-plugin-svelte/blob/main/docs/faq.md#what-is-going-on-with-vite-and-pre-bundling-dependencies).

 CDNs can generally be used without any need for a library. However, there are a number of libraries with Svelte support that make it easier. [`@unpic/svelte`](https://unpic.pics/img/svelte/) is a CDN-agnostic library with support for a large number of providers. You may also find that specific CDNs like [Cloudinary](https://svelte.cloudinary.dev/) have Svelte support. Finally, some content management systems (CMS) which support Svelte (such as [Contentful](https://www.contentful.com/sveltekit-starter-guide/), [Storyblok](https://github.com/storyblok/storyblok-svelte), and [Contentstack](https://www.contentstack.com/docs/developers/sample-apps/build-a-starter-website-with-sveltekit-and-contentstack)) have built-in support for image handling.

 ## Best practices
 
 - For each image type, use the appropriate solution from those discussed above. You can mix and match all three solutions in one project. For example, you may use Vite's built-in handling to provide images for `<meta>` tags, display images on your homepage with `@sveltejs/enhanced-img`, and display user-submitted content with a dynamic approach.
