How to use these

Each page has a live preview, the code in separate HTML, CSS and JavaScript tabs, and a download button that gives you a single working file. Copy the tab you need, or take the whole thing.

There is no licence to read and no attribution required. Use them in client work, in commercial products, in anything. They are starting points, not finished designs — change the colours, change the words, and cut what you do not need.

The code is written to be edited by a person. No utility-class soup, no build step, no abstraction between you and the CSS. Where a Tailwind version makes sense, there is a separate tab for it.

What every template here does

tab

Works with a keyboard

Real buttons and links, visible focus rings, Escape closes what it opens. Tested by tabbing through it, not by assuming.

aria

Announces itself

Labels on every input, aria-expanded on every toggle, and no icon-only control without an accessible name.

↔

Responsive without effort

Intrinsic grids that reflow on their own rather than a stack of breakpoints to maintain.

0kb

No dependencies

No jQuery, no framework, no icon font. Everything is HTML, CSS and a little vanilla JavaScript.

~

Respects reduced motion

Anything that animates is switched off under prefers-reduced-motion.

/*

Explained, not just given

Each page says why the code is written the way it is, and what breaks if you change it.
