+### Overwrite default line-height
+
+Sometimes it may be useful to override the default line height that you set in your config. Therefore, this plugin supports the Tailwind font size line-height shorthand. This works as follows.
+
+```html
+<h1 class="text-9xl/snug">The quick brown fox jumps over the lazy dogs</h1>

+
+See the [official Tailwind documentation](https://tailwindcss.com/blog/tailwindcss-v3-3#new-line-height-shorthand-for-font-size-utilities) for more information.
