:not(:empty) with space in CSS

:not(:empty) with space in CSS

Problem

I would like to apply a CSS rule on a div when it is Empty. Problem: the application which generate the html puts a space:

So I tried:

.my-div:not(:empty) {...}

But it doesn't work because of the space.

How can I do that in CSS ?

Thank you

Solution

You cant

(unfortunately)

The :empty selector is the only way in CSS of detecting content, and also proves positive for whitespace:

The :empty pseudo-class represents any element that has no children at all. Only element nodes and text (including whitespace) are considered. Comments or processing instructions do not affect whether an element is considered empty or not.

Dont forget about the separation of concerns, HTML for content, CSS for styling and JS for functionality - as such, you either need to remove the whitespace from your HTML (content) or apply a class depending on its presence, or strip it using JS (functionality).

With that said, elements only containing whitespace should collapse by default, so long as the space in question isnt a non-breaking space
