• Move h1 outside and below the image container
• Add border-top to h1
• Add border-top to sidebar h2
• Change hr color to #eee
• Remove border on .feature-box and add background #eee
• Change buttons overlaying image to links

I'll post a mock I did on slack

@JamesWChan Can we change:

• the border colour on the thumbnails (.thumbnail-container) to #26262a
• The focus state of the links on the images (.overlay a:focus) is currently #26262a (should be white?), so the link text vanishes when clicked

Thanks :)

I have attempted to fix the overlay focus so you may not need to fix this @JamesWChan - see here https://github.com/nationalarchives/tna/commit/1fe6121b0cb58be4db41939672b4b185fb486941
