</button>About Floating Action Button
Floating Action Button is a button built with transforms and layered shadows. Its stylesheet runs to 37 lines across 5 rules, declaring 15 distinct properties. It styles hover and active states explicitly, so the component responds to interaction rather than sitting still. Every format shown on this page is the same component, so you can take HTML and CSS depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- Dense interfaces and admin panels, where dozens of controls share a screen, where a minimal and floating button fits the surrounding design
- Repeated use across a page, since there is no animation to become tiring when several appear together
- Palettes built around blue and white, where this button can be dropped in without retheming
- A quick starting point you intend to modify, since the CSS is short enough to read in one pass
How it works
The base rule sets the shape with border-radius, display, height and width. Movement is done with transforms rather than by changing position or size, which is what keeps it smooth: transforms are composited and do not force the browser to lay the page out again. State changes are eased with a transition, so hovering does not snap.
Accessibility
Built on a native <button> element, so keyboard focus and screen reader semantics work without extra attributes. No focus style is defined. Add one before shipping, or keyboard users lose track of position. That is one thing to fix before this ships in front of users.
Browser support
Everything this component uses has been supported across browsers for years, so no fallback is needed.
