Date and time
The .input class styles date, time and datetime pickers, with a picker icon that follows the theme.
Example
<div class="grid grid-cols-2 gap-3 max-w-sm">
<input type="date" class="input" value="2026-10-13" aria-label="Date">
<input type="time" class="input" value="09:30" aria-label="Time">
<input type="datetime-local" class="input col-span-2" value="2026-10-13T09:30" aria-label="Date and time">
</div>Classes
1 classes. Click a name to copy it. Utilities on the same element always win over component defaults, so any of them can be adjusted with plain utility classes.
| Class | Type | What it does |
|---|---|---|
| Base | Base class of the date and time. On an <input> in the example. Sets block display, width, height, padding, text size and text style, and 9 custom properties.CSS |
Usage
Components ship inside the same stylesheet as the utilities. There is nothing else to install and no script to load: link Monsoon and write the markup.

<!-- Date and time: start from the base class, then add modifiers -->
<div class="grid grid-cols-2 gap-3 max-w-sm">
<input type="date" class="input" value="2026-10-13" aria-label="Date">
<input type="time" class="input" value="09:30" aria-label="Time">
<input type="datetime-local" class="input col-span-2" value="2026-10-13T09:30" aria-label="Date and time">
</div>Theme it with --seed on any ancestor, for example style="--seed: #0d9488", and force a scheme with class="dark" or class="light" on a wrapper.
Accessibility
- Give every control a visible
labellinked withfor, or anaria-labelwhen the purpose is obvious from context. Link help and error text witharia-describedby; invalid styles use:user-invalid, so they appear only after the user interacts. - Every interactive part shows a visible focus ring with
:focus-visible, and tone colors pair with-foregroundtokens that keep text at 4.5:1 or better in light and dark mode.
