(Theme: Buenos) Change width of post

Hi there,

I searched the forum & learned how to change the width of the main column.

( #main {
width:720px;
}

#sidebar {
width:200px;
}

It did widen my main column but I cannot figure out how to enlarge the actual posts. This was my main goal. To try and make my posts wider.

I have tried erasing and uploading them again but that’s not working.

I have also made my sidebar too small.

Any help would be appreciated… even if I just go back the original format.

Thanks,

K
