</button>About Matrix Code Button
Matrix Code Button is a button built with a keyframe animation, layered shadows and pseudo elements. Its stylesheet runs to 51 lines across 7 rules, declaring 23 distinct properties. It styles hover state explicitly, so the component responds to interaction rather than sitting still. The animation is driven by keyframe sequences named matrix-fall and matrix-glitch, 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
- Sites with a strong established look, where a neutral control would sit awkwardly, where a matrix and code button fits the surrounding design
- A single prominent button rather than a row of them, since the matrix-fall animation runs continuously and several at once compete with each other
- Palettes built around green and black, where this button can be dropped in without retheming
- Places where one control is meant to be memorable, since 51 lines of CSS is a real investment for a single element
How it works
The base rule sets the shape with border-radius, padding and position. 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 matrix-fall and matrix-glitch. 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.
