Exclamation Triangle

The exclamation-triangle icon is a widely recognized symbol for warning or caution, commonly used to indicate potential hazards or issues. Its origin stems from safety and warning signage, now adopted in digital interfaces to convey similar meanings. The icon signifies a need for user attention to avoid potential problems.

This icon is frequently seen in software applications, websites, and digital platforms such as system warnings, error messages, or safety alerts. For example, it might appear in a web browser to warn users about potentially malicious websites or in system settings to alert about low battery levels.

From a UX perspective, the exclamation-triangle icon effectively communicates a sense of caution, prompting users to take necessary actions or be aware of potential risks. Its use helps in guiding users through interfaces safely and efficiently.

Exclamation Triangle is one of 450 icons in Pixel Icon, made by HackerNoon and released under CC BY 4.0. 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 ExclamationTriangleIcon to components/icons/pixel-exclamation-triangle.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 ExclamationTriangleIcon 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 Exclamation Triangle icon, or any of 450 Pixel 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="Exclamation Triangle", so screen readers say what it does.

Yes. ExclamationTriangleIcon passes every SVG prop to the svg element, so <ExclamationTriangleIcon 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, with credit: CC BY 4.0 asks you to credit the author (HackerNoon) where you use the icons. The full terms are in the license, linked on this page.
