I'd like to make a theme that displays the text content in columns. However, as my theme is a horizontal layout, I need an undetermined number of columns. I have no problems making the columns themselves... it's just plain HTML + CSS.
The real problem is to get the content, get the number of characters, divide by 800 (my char limit), round it up, then print a <td>content here</td> for each 800-char packet. The Css will take care of the rest.
As you see, I've got a fairly good idea of what to do, and if it was just PHP I'd already have finished. But I just can't seem to find: a) a way to get the length of the content; and b) a way to make the above into something usable by the template...
