  <p>It was this howling and firing of the guns at Ripley and St. George's Hill that we had heard at Upper Halliford. The Ripley gunners, unseasoned artillery volunteers who ought never to have been placed in such a position, fired one wild, premature, ineffectual volley, and bolted on horse and foot through the deserted village, while the Martian, without using his Heat-Ray, walked serenely over their guns, stepped gingerly among them, passed in front of them, and so came unexpectedly upon the guns in Painshill Park, which he destroyed.</p>

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
