Not sure if this is the way to do it, but I'll try to make this understandable.
Two Columns
<div class=pull-left>WRITE ALL YOUR TEXT HERE FOR THE LEFT COLUMN.</div><div class=pull-right>WRITE ALL YOUR TEXT HERE FOR THE RIGHT COLUMN.</div>
I use this when I am posting something in English and some other language.
I'll put English on the left, then Spanish (for instance) on the right.
It is very tricky to get right, but impressive when you get it.
Superscript
<sup> Yourtext </sup> where your text is smaller and higher than the surrounding text.
Exponents (like square and cube)
3<sup>2</sup> 32
Align left
<div class="pull-left"><put your image link here/></div>
Align Right
<div class="pull-right"><put your image link here/></div>
Again, these are also VERY tricky.
So if you want an image to the left with text to the right of it, use the first one.
Similarly, image to the right and text to the left, use the second one.
inserts a blank space in text
I hope this helps
