Hacker News: alternating comment backgrounds

Gives every other comment a faint background so neighbouring posts are easier to tell apart.

Code to copy

/* Alternate a faint background between comment rows */
.comtr:nth-of-type(even) .commtext {
  background: rgba(0, 0, 0, 0.035) !important;
  box-shadow: 0 0 0 4px rgba(0, 0, 0, 0.035) !important;
}

How to use this example

1. Copy the code with the button above.
2. Install JustZix (2 minutes) and open the extension on the target page.
3. Add a new rule matching that page.
4. Paste the code into the rule's CSS panel and save — the effect appears instantly.
