Anyone got the spacehey IDS?

Currently trying to learn the basics of CSS and html to make my own layouts. What i was wondering is if anyone had the ID's for the profile and blog sections; as i wanted to make a blog template as well. Currently I'm just editing a layout made by bela (see on my profile) to try to get it to fit the blog format; but it isn't working as I have no clue what the ids are for each section of the webpage. And I cant seem to find any documentation either.
