</button>About Liquid Wave Button
Liquid Wave Button is a button built with a keyframe animation, gradient fills and pseudo elements. Its stylesheet runs to 47 lines across 7 rules, declaring 19 distinct properties. It styles hover state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by a keyframe sequence named wave-flow, which you can retime or remove without touching the rest of the styling. 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
- Landing pages where one moving element earns attention rather than competing for it, where a liquid and wave button fits the surrounding design
- A single prominent button rather than a row of them, since the wave-flow animation runs continuously and several at once compete with each other
- Palettes built around cyan and blue, where this button can be dropped in without retheming
- Places where one control is meant to be memorable, since 47 lines of CSS is a real investment for a single element
How it works
The base rule sets the shape with border-radius, height, padding and position. The fill is a gradient rather than a flat colour, so it is a single background declaration with no image to load. A pseudo element carries part of the effect, which keeps the markup to one element while giving the CSS a second surface to animate. State changes are eased with a transition, so hovering does not snap. The looping motion comes from wave-flow. Changing the animation-duration is usually the only edit needed to make it faster or calmer.
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. Animates without a prefers-reduced-motion guard. Wrap the animation in that query if motion sensitivity matters to your audience. Those are 2 things 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.
