I decided I want to change the two 160wides to one 300wide and then use tables to chop it up.
I change the width and it doesn't change and stays at 160.
here in my style.css
#serendipityRightSideBar {
width: 300px;
Is it like welded to 160px somewhere else that I forgot about?
Other changes I make to it do take hold, just not the width.
I have removed everkything in Left sidebar in config plugins.
I have greyed out the css for leftsidebar which didnt matter.
