I created a small custom style that changes the appearance of the comments in the Q & A section. Screenshot:
For comparison, I provide a screenshot of the same page without a style:
A vertical bar to the left of comments has been removed, due to which the comment is easily confused with a blockquote, an indent is added instead. The username and time of adding a comment is now shown not after the text, but before it. In my opinion, it is so much easier to understand which text belongs to whom, and now the boundaries between comments are better visible. ')
The style can be downloaded and installed from here: userstyles.org/styles/52830/habrahabr-qa-nice-comments
