# Arx Framework
A full Bootstrap-replacement CSS skeleton with 12-column grid, buttons, forms, cards, navbar, alerts, badges, tables, and utilities. Dual light/dark theme support.
## Installation
```html
```
No build step. No JavaScript dependency. Arx does not bundle jQuery; add it separately if needed.
## Theming
Add `arx-dark` to `` or `` for the dark theme.
```html
```
Toggle and persist via JavaScript:
```js
var saved = localStorage.getItem('arx-theme');
if (saved === 'dark') document.documentElement.classList.add('arx-dark');
document.getElementById('toggle').addEventListener('click', function () {
var isDark = document.documentElement.classList.toggle('arx-dark');
localStorage.setItem('arx-theme', isDark ? 'dark' : 'light');
});
```
