Tightening up the body text

As I said earlier, I thought WordPress was not using the main text space effeciently. The default text-size if far too large, and the complete line breaks between paragraphs use too much space. Too many pixels are being wasted. Here are my changes:
h4 {font-weight: bold; margin-top: .5em; margin-bottom: .5em;}
body {font-size: small; font-family: verdana, sans-serif;}
p {margin-top: .5em; margin-bottom: .5em; text-indent: 2em;}
ol,ul {margin-top: 0; margin-bottom: 0;}
li {margin-bottom: .5em; }
You can see the results at https://halsmith.info/wordpress/index.php
The text-indent looks ‘different’, and this may turn some people off. But it makes for increased readability, and for me this is most important. You could even go with a font-size a notch smaller, but some people don’t know how to set up their monitors and their browser, and it might give them a problem. I thought ‘small’ was a conservative choice.
I welcome some feedback, how does it look to you?
