Hello. I'm using Bueno theme and there's lots of negative space on both the left side of the main text column for posts and on the right side of the sidebar. I'd love to be able to reduce the overall page margins and increase the size of the column in which I publish my posts. I've found the code that allows me to change the size of the column and sidebar but because I don't know how to change the margins, it means that parts of my sidebar and column are getting cut off behind the negative space of the margins when I enlarge them.
Thanks very much!
The blog I need help with is photomadly.wordpress.com.
