Moon Fill

The moon-fill icon represents active dark mode and enabled night theme states with a filled design for clear visual confirmation. Featuring a solid filled crescent moon, this variant provides visual distinction for activated dark themes and currently enabled night modes compared to the outline moon icon.

In modern applications like active dark mode indicators in theme toggle buttons showing current state, enabled night mode displays in reading apps like Medium and Substack confirming dark theme activation, or system preference indicators in operating system settings showing dark appearance is active, you'll see this filled icon confirming night theme status. It appears in browser extension icons for dark mode tools when active, in mobile app settings showing enabled night shift, or in website theme switchers indicating current dark mode state.

From an interaction design perspective, the filled moon communicates more than just 'dark available' - it specifically indicates currently active dark mode, confirmed theme preference state, and the visual feedback that dark theme is successfully applied. This filled state helps users immediately understand their current theme preference without needing to check settings.

Moon Fill is one of 458 icons in Akar Icons, made by Arturo Wibawa 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 MoonFillIcon to components/icons/akar-icons-moon-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 MoonFillIcon 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 Moon Fill icon, or any of 458 Akar 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="Moon Fill", so screen readers say what it does.

Yes. MoonFillIcon passes every SVG prop to the svg element, so <MoonFillIcon 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 Akar Icons, Arturo Wibawa and the license.

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