Slightly off topic, but when a page with minimal styling like this comes by, how do you typically view it?

I usually do something like this in the inspector:

  body{
    width: 601px;
    margin: auto;
    font-size: 1.3em;
    color: #483f3f;
    line-height: 1.5em;
  }

But that's a pain to write out each time.

I'm not against un-styled websites at all, but I wish they were more readable by default.
