Header 3

The header-3 icon represents a tertiary heading or title in a document or page. It is commonly used to define sub-subheadings or tertiary titles in a section or document.

In software and digital design, the header-3 icon appears in word processing software like Microsoft Word, Google Docs, or Apple Pages. It may also be used in desktop publishing software, email clients, or web design tools.

From a UX perspective, the header-3 icon communicates a sense of lower-level importance or hierarchy. It helps users understand the structure and organization of content, and it often appears in contexts where users need to create or edit text.

Header 3 is one of 940 icons in Jam Icons, made by Michael Amprimo and released under MIT. 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 Header3Icon to components/icons/jam-header-3.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 Header3Icon 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 Header 3 icon, or any of 940 Jam Icons 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="Header 3", so screen readers say what it does.

Yes. Header3Icon passes every SVG prop to the svg element, so <Header3Icon 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 Jam Icons, Michael Amprimo and the license.

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