I have 3 issues with one website I need to resolve:
1. Grid lines showing up even with Border = 0
2. When I make the home-page post 'sticky', it shows a grey-ed out (ie the area is coloured grey), but is OK when not sticky.
3. I'm using Amazon carousel widgets. Whenever I save the page/post in WP Admin, it adds 4 blank lines above and below the widgets, which I have to go back and remove manually.
I can provide a Word document with screenshots illustrating the problems (website appearance and WP-admin area).
