How do I change font size of the title on "How it works" please ?
If you want to change the font size of the content in the How it works item, you can use simple inline CSS inside of it.
The question was how to change the TITLE size, not the content
Oh, sorry, my bad.
To change the title, you will have to create and use Custom CSS Code.
If you need help with it, please, let me know, but I will need a link to your website.
