Hi, I recently added a basic code block to a page (not on footer) to remove the header and footer (we needed a 'landing page' to be reached by URL but hidden on the site, without showing the site nav or connecting to other pages). I found this code by Googling it, and at first, it worked. (source: https://www.mehdiaoussiad.com/blog/squarespace-remove-footer-and-header-from-one-page) <style> .header, #footer-sections{ display:none !important; } </style> Now, the design is breaking across our site! Whole chunks of text and buttons have gone missing, fonts have swapped, photos are blown out and wonky, etc. I am not an experienced developer, and need your help! Can someone please: 1) Tell me how to do this correctly (if that's possible to do) and/or 2) Tell me how to remove this code block from our site (I can't find it anywhere now) and 3) Tell me if removing the code will make the site secure again Many thanks!
