the width for the main column in single post (or page) is set in style.css:
.page .site-content,
.single-post .site-content {
width: 812px;
}
for single posts plus picture sidebar, try and add this line to the end of style.css (or better use a custom css plugin for the edits):
.single-post .site-content
{
width: 528px;
}
weird, that the picture sidebar is now on the outside (?)
Thanks a lot alcymuth.
I put that code in but I didn’t realise how much longer that made the pages and changed it back.
Thanks for your help 🙂
