Giving read emails a white background in Gmail (and increasing spacing)

The latest design of Gmail is a big improvement but there are two small changes I like to implement that make a big difference.

1. Getting rid of the light grey background for unread emails
2. Increasing the top and bottom spacing on all emails in the inbox

Gmail’s built-in settings do not allow you to do this so you need to first install the Stylus browser extension (Firefox / Chrome). Once installed create a new style that applies to the domain mail.google.com and add this CSS:

div.AO tr {
	
    background-color: #FFFFFF;
 
}

div.AO tr td {
	
    padding-top: 5px !important;
    padding-bottom: 5px !important;
	
}

This applies your CSS on top of the existing Gmail CSS.

Your inbox will then look like this:
