This is just example text, as is everything on this page. This is an example of normal copy. Above is an example of Heading 1, which is set with the left-most button with the "A" on the menu bar above. Below are examples of other Headings as well. To the right is an image, aligned right, with 30 pixels of padding to its left...you can see all that if you click on the image and then click on the Image icon in the menu bar.
We really only use Headings 1-3, because the others become smaller than the copy and that's just sad for them.
