Trouble with Website Display After Recent Update - Need Help with CSS and Browser Compatibility Issu

After applying a recent update to my website coach hire, I've noticed that certain elements are not displaying correctly across different browsers. The layout seems broken in Chrome, and some CSS styles aren't rendering properly in Firefox. I suspect there might be issues related to CSS or browser compatibility. Has anyone else experienced similar issues after an update, and what steps can I take to troubleshoot and resolve this? Any advice on debugging or specific tools to use would be greatly appreciated!
