'Take part' pages might not have enough bottom spacing

[andysellick]

The spacing between the main column content and the sidebar content on pages like https://www.gov.uk/government/get-involved/take-part/improve-your-social-housing on mobile is a little tight, particularly when compared to the spacing between the top of the text in the main column content and the image above it.

This particular route is currently being migrated into frontend from government-frontend (hence why I'm logging this here). It may also be that other pages have a similar issue.
