Classes

14 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.

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.

index.html
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/monsooncss">

<!-- Textarea: start from the base class, then add modifiers -->
<div class="grid gap-3 max-w-sm">
  <textarea class="textarea" placeholder="Tell us about your project" aria-label="Project"></textarea>
  <textarea class="textarea textarea-autosize textarea-sm" aria-label="Notes">This one grows as you type.</textarea>
</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 label linked with for, or an aria-label when the purpose is obvious from context. Link help and error text with aria-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 -foreground tokens that keep text at 4.5:1 or better in light and dark mode.
InteractiveTextarea autosizeGrows the textarea with its content. Browsers with CSS field-sizing do it natively; the script measures the others. max-height still caps it. Needs monsoon.js.FormsInputText, email, password, number, search, url and tel inputs with sizes, tones, ghost and filled variants.FormsDate and timeThe .input class styles date, time and datetime pickers, with a picker icon that follows the theme.FormsSelectA styled native select with a theme aware chevron, sizes, tones and variants.
