I was able to remove the sidebar from my blog posts themselves, but this now leaves a big white space on the right of the page where the sidebar used to be. How do I expand the width of my post to be the full size of the page (centered on the browser, example: http://www.elisadoucette.com/purging-the-toxic-from-life/) Also, is there any way to customize the sidebar to use selected and created widgets in the blog page sidebar rather than the programmed ones?
Go to blog.php present in your theme directory and follow the instruction as shown in image given below
