Howdy Customizr designr!
Here’s a quick tip to simply add content before and after your text logo with CSS only.
We use the CSS pseudo classes ::before and ::after to do that.
Important: in this example double quotes are escaped with ‘\’ to use the code in the custom css section. You can remove these if you use this code in the style.css file of your child theme.
You can play with the css properties to add padding, margins, borders …etc
Hope this will be useful for you!
