Are you’re looking to replace <br> break with a space using only CSS? I’ve got a solution for you then. To do this we’ll use CSS to change the content of the br tag which will prevent it from making a line break. Then we’ll also add content using the :after pseudo-element. That will ensure the <br> tag is replaced with a space.
Here is what that looks like. You can copy and paste this into your style sheet file or in-line CSS.
