Add style for sup, sub and blockquote

Hello!
Thanks for great theme for Drupal!
I always use Framework for my themes, but some styles is missing. There are sup, sub and blockquote styles.
Can you added styles for these tags?

In my themes I use these styles:

sup, sub {
  vertical-align: baseline; 
  position:r elative; 
  font-size: 0.7692em; 
  line-height: 1; 
}
sup {
  bottom: 1.4ex;
}
sub {
  top: .5ex; 
}

blockquote {
  margin: 1em 3em;
  border-left: 2px solid #999;
  padding-left: 1em; 
}
