Warning Box

The warning box icon represents a notification or alert that draws attention to a potential issue, risk, or problem that requires attention. It serves as a visual indicator to caution users about a possible danger, error, or unexpected situation. The warning box icon is commonly used to prevent accidents, errors, or misunderstandings.

In software and digital platforms, the warning box icon appears in various contexts, such as error messages, security alerts, or notifications about system maintenance. For example, Figma and Notion use warning box icons to alert users about potential issues or errors in their designs or documents.

From a UX perspective, the warning box icon communicates a sense of caution, concern, or urgency. It helps users quickly identify potential problems and take corrective action to avoid negative consequences. The icon's presence can also reassure users that they are being informed about potential risks or issues.

Warning Box is one of 486 icons in Pixelarticons, made by Gerrit Halfmann 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 WarningBoxIcon to components/icons/pixelarticons-warning-box.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 WarningBoxIcon 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 Warning Box icon, or any of 486 Pixelarticons 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="Warning Box", so screen readers say what it does.

Yes. WarningBoxIcon passes every SVG prop to the svg element, so <WarningBoxIcon 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 Pixelarticons, Gerrit Halfmann and the license.

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

Its tags are action, status, security, notification, caution and risk. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Warning Box in another set.
