FAQ
Frequently asked questions
What the Underline 16 Solid icon means and where it's used, then how to install, style, label and license it.
The underline icon represents text formatting and emphasis with its underlined text design showing text decoration. This formatting symbol has become the universal indicator for underline text, emphasis markup, text decoration, and formatting options across all modern text editors and document applications.
In modern applications like email composers or message formatting in platforms like Gmail, you'll see this underline indicating text formatting, message emphasis, and style options. It appears in email interfaces where formatting visibility requires clear visual cues, or in message systems where text decoration features need explicit representation.
From an email composition perspective, the underline design communicates more than formatting - it specifically indicates message emphasis, text decoration, and the stylistic nature of underline versus hyperlinks. This distinction helps users recognize formatting features versus link insertion.
Underline 16 Solid is one of 1,288 icons in HeroIcons, made by Refactoring UI Inc and released under MIT. It is drawn on a 16 × 16 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 Underline16SolidIcon to components/icons/heroicons-underline-16-solid.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 Underline16SolidIcon 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.
Yes, if your project has @heroicons/react/16/solid: Underline 16 Solid is `UnderlineIcon` there, used as <UnderlineIcon />. The shadcn.io MCP server answers with that import when it finds the package. Without it, copy the icon from here.
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 16 Solid icon, or any of 1,288 HeroIcons 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 16 × 16 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 16 Solid", so screen readers say what it does.
Yes. Underline16SolidIcon passes every SVG prop to the svg element, so <Underline16SolidIcon 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. MIT 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: MIT 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 HeroIcons, Refactoring UI Inc and the license.
Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
Its tags are text, style, formatting, emphasis, markup and decoration. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Underline 16 Solid in another set.
HeroIcons draws many icons in several styles: Solid next to the default. Open the library and pick a style above the grid to see Underline 16 Solid's siblings in it.
