Tailwind CSS v4 utilities for popular icon sets. This lets you include icons with Tailwind LSP auto-complete and thanks to Tailwind’s tree-shaking, your output CSS will only include the icons you actually use.

• Bootstrap Icons — twbs/icons
• Tabler Icons — tabler/tabler-icons
• Flag Icons — lipis/flag-icons

npm install maskicons

Just import the package in your CSS file after tailwindcss:

@import "tailwindcss";
@import "maskicons";

You can alternatively import just the icon sets that you need:

@import "tailwindcss";
@import "maskicons/tabler-outline";
@import "maskicons/tabler-filled";
@import "maskicons/bootstrap";
@import "maskicons/flags";
@import "maskicons/flags-square";

Then use the CSS classes on <i> tags to render icons.

<i class="tabler-heart-outline"></i>
<i class="tabler-star-filled"></i>
<i class="bootstrap-folder"></i>
<i class="flag-us"></i>
<i class="flag-gb-square"></i>

By default, icons are 1em tall, which means they scale with the current font size. You can size them using Tailwind's text-* utilities:

<i class="tabler-heart-outline text-sm"></i>
<i class="tabler-heart-outline text-base"></i>
<i class="tabler-heart-outline text-2xl"></i>

Alternatively, you can use h-* utilities for explicit sizing:

<i class="tabler-heart-outline h-4"></i>
<i class="tabler-heart-outline h-6"></i>
<i class="tabler-heart-outline h-8"></i>

Note: Flags have a 4:3 aspect ratio by default. Use the -square suffix for 1:1 flags (e.g., flag-us-square).

By default, icons inherit the current text color. You can also use the icon-* utility to set a specific icon color. This can be applied to a parent element to color all icons inside it:

<div class="icon-blue-500">
  <i class="tabler-heart-outline"></i>
  <i class="tabler-star-outline"></i>
</div>

Note: Flag icons are full-color and do not respond to the icon-* utility.

By default, icons are displayed inline-block and vertically aligned to look great next to text content. But you can can easily override this with the block utility.

Any text inside the icon element is visually hidden but remains accessible to screen readers. You can use this to provide alternative text:

<button><i class="tabler-trash-outline">Delete</i></button>

The icon utilities use :where selectors so they have the lowest precedence. This is why all other utilities such as size-* will override the defaults.

The Tabler icons are ~687 bytes on average and the Bootstrap icons are ~914 bytes on average. They should compress well due to the duplicated rules. And Tailwind only includes the icons you actually use.
