Underline Fill

The underline-fill icon represents a text formatting option used to add an underline to selected text. This feature is commonly found in word processors and text editors.

In software applications like Microsoft Word, Google Docs, and Notion, the underline icon is used to emphasize text and make it more readable. The icon is often used in conjunction with other formatting options like bold and italics.

From a UX perspective, the underline icon communicates the ability to add visual emphasis to text, making it easier for users to distinguish between different sections of content. When used consistently across an interface, the underline icon helps users understand the functionality of the text formatting options.

Underline Fill is one of 3,320 icons in MingCute Icon, made by MingCute Design and released under Apache 2.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds UnderlineFillIcon to components/icons/mingcute-underline-fill.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed UnderlineFillIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Underline Fill icon, or any of 3,320 MingCute Icon icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Underline Fill", so screen readers say what it does.

Yes. UnderlineFillIcon passes every SVG prop to the svg element, so <UnderlineFillIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming MingCute Icon, MingCute Design and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
