How to add Tailwind classes only when the user can hover

February 7, 2022

I recently had a situation where I wanted to have a Tailwind class only apply when the user had the ability to hover (only on a computer with a mouse, but not on a phone).

Tailwind CSS doesn’t have this ability built in, but you can add it as custom modifier (like the sm: modifier). Make this change in your tailwind.config.js file, in addition to what’s already there:

module.exports = {
    theme: {
        extend: {
            screens: {
            	"can-hover": { raw: "(hover: hover)" }

Then, re-compile your Tailwind CSS (in some setups, you don’t have to run a separate command, because Tailwind CSS is always being re-build according to what you’re writing in the background).

Now, you’ll be able to use the modifier with any Tailwind CSS property:

<div class="can-hover:blur hover:blur-none"></div>

The above Tailwind class means, “if the device has the ability to hover, add a blur. If it doesn’t have the ability to hover, don’t add a blur. Regardless, un-blur when the user hovers over it.”
