With Word Web App, as you would expect you can easily edit and change not only the font but the styles also, as well as paragraph adjustments. You can bold, italic, underline, superscript, sub-script, justify, and change font colour. Even though here you don't see a ruler and the margins are not apparent, these are applied by the document template on the host computer when downloaded. So even though it looks very widescreen for a Word document, when downloaded or printed the margins are applied.

Plus, I don't get to pick the essay titles, unfortunately, so I just have to go with what I've got.)
