Add Tight Background to Text

Hello everyone - Does anyone know how to achieve a highlight or box behind individual lines of text?

Here's an example: https://scalabilityfactor.com/

This is not my site but it was built on squarespace so clearly it is possible. Would love any help you can provide! Thanks!

FYI - I figured it out.

Simply add the following CSS code to your site and adjust as needed:

/New h1 heading style/h1 em,h1 em {background-color: #3e00d6;box-shadow: 0.2em 0 0 #3e00d6, -0.2em 0 0 #3e00d6;}

This means when you italicize your H1 heading on your site, it will add the background to the text. You can play with the borders/shadow and the color to get the look you want.
