I've applied the single column layout proposed by Christy Nyiri. I personally think it looks fantastic. 

Here are some WordLand styles.

Heading 1

Heading 2

Heading 3

This is a block quote. (This doesn't seem to be styled yet.)

Bold, italics, underlined (hmm, it's not underlined). 

An ordered shopping list:

1. Bread
2. Milk
3. Eggs

Notes as an unordered list:

•  The next/previous links have returned to the WordPress default instead of large arrows only. Update: That was my bug, now fixed.
• As Christy noted, the child elements of the Post Template block are a little weird at inheriting global padding, as evidenced on mobile.
• Are H1 and H2 way too big? Update I've bumped down the font-sizes of H1 to H3 to large, medium, and normal. H1 now matches the size of the post title, and H3 matches the size of normal paragraph text.

Here's a paragraph that appears under the unordered list.
