If you feel confident with your
basic formatting skills, lets take a look at some more advanced options.
Most of the places you can post things in a text box on TA, you can utilize HTML code, allowing you many more options than just the basic formatting button bar provides.
If you're familiar with HTML coding I probably won't have anything new for you here. If you are not familiar with HTML coding, but feel confident you can learn a few tid-bits, then this post should help you.
All HTML tags use the less-than and greater-than symbols. The code starts with the less than < and ends with the greater than >. Most code needs a closing code also, this is done with the forward slash symbol /. This really is the most basic of instruction, if you need more detail I suggest
searching for a HTML tutorial.
So for example entering:

I'll post others if I think of them, but these are the main codes I use often to make my posts more aesthetically pleasing. Remember not to over format, it doesn't take much to make a post look sloppy and disorganized.
