I’m rebuilding a site in Joomla 4 and would appreciate your guidance on a couple design issues on the home page. The working migration is at:
https://bonnieu23.sg-host.com/
The Original site is at: https://dogclubofhollywood.com

1) The main menu and content area is flush at the top & should be below the logo. The other internal pages are laying out fine under the logo.

2) The hover gallery under the slider needs to have 5 in the row across with no extra space right & left & top & bottom (if any 5 pixels would be fine.) I used a CSS in the previous site which is not working in the migrated site.
the previous custom CSS is:
/* Homepage Gridgallery module position adjustment */
#top1_modules.block_holder {padding: 0 5px;}
.module {padding-bottom: 0px;}
