There is no current official way to do a layout (that is a feature in the works). However, @Camazotz figured out how to come up with its own "skins" for its profile. It might be a good resource.

you can use the style tag in your commision’s textbox and do all the coding with just spaces, no linebreaks, otherwise the code won’t work, you can see what to change by using inspect element, hovering over what element you want to change and edit the code from there so you see it change in real time if it works, then copy and paste it into your textbox with no linebreaks
