Navigation and overlays
Back to top
A round button fixed to the corner that fades in after the page scrolls, driven by a scroll timeline where supported. Use .back-to-top-static to place it inline.
Example
<a href="#top" class="back-to-top back-to-top-static" aria-label="Back to top"></a>Classes
2 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 back to top. On an <a> in the example. Sets generated content, width, height, background, fixed position and offsets.CSS |
|
| Modifier | Modifier, combined with the back-to-top class. On an <a> in the example. Sets static position.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.
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/monsooncss">
<!-- Back to top: start from the base class, then add modifiers -->
<a href="#top" class="back-to-top back-to-top-static" aria-label="Back to top"></a>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
