Wow, thank you. I've never touched that part of the design site before, I was a bit concerned by the notice; Warning: Adding custom CSS to your site can break your design. Please use caution when using this feature. Our support team will be limited in their ability to help you with design related issues if you have custom CSS.
What do you think of the look of the first page now on mobile?
Thanks for your help. Jen
p.s. what's the chances of really messing up your site inside the CSS?
Is there a way to backup with Squarespace? So if you break something you can go backwards?
