Everyone is messing with CSS right now, but there are also plenty of just regular HTML tags that cohost lets you put into the posts. I figured I would make a reference of what those tags were and what they look like for anyone wanting to do something Markdown doesnt quite do.

Containers: <div>, <span>
There are two tags primarily used to encapsulate and organize other HTML tags, DIV and SPAN.If you want to know the technical details of the difference between the two... google it.
The short of it is that DIV is a "block" container, it is meant to represent an independent block of content. Most browsers will render a DIV as wide as the space it is contained in, effectively making any elements after a DIV element render in the next "line".
SPAN on the otherhand is an "inline" element and is meant to contain only elements that can be rendered inside of other contnet like a text block. It does not take up the whole space it is rendered in but also has no inherit width.
Of course everything I just said up there is only true most of the time, and historically everyone has ignored the rules on how you are supposed to use DIV and SPANs and browsers have created whole sets of exceptions and rules to how they work.
If you really really need precise container control, go google Flexbox.
