</button>About Split Action Button
Split Action Button is a button built with transforms and layered shadows. Its stylesheet runs to 37 lines across 6 rules, declaring 17 distinct properties. It styles hover state 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, CSS and Tailwind depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- Toolbars and utility screens, where clarity outranks personality, where a split and action 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 purple and white, where this button can be dropped in without retheming
How it works
The base rule sets the shape with border-radius, display, height and padding. 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.
