Headers
Headers are a great way to format text without using font size and all that.
They can also be used as selectors in css, so you could type <h2> text </h2> with a css sheet of h2 {background: pink; color: purple; font: bold 19px verdana;} to get size 19px bold text in the color purple with a pink background. The 2 can be any number 1 through 6, with 1 being the largest size.
