There's a newer version of Pico CSS!

We love .classes

As a starting point, Pico chose to be as neutral and semantic as possible using very few .classes

But of course, .classes are not a bad practice at all.

Feel free to use modifiers.

<button class="warning">Action</button>

Just try to keep your HTML clean and semantic to keep the Pico spirit.

<button class="button-red margin-large padding-medium">Action</button>
