It again proved how silly WordPress is: I can’t find any theme with wide content area. Why do we have to waste almost a third of page area in EVERY WordPress theme? I read many articles about how to make custom CSS to widen the content column but no magic happened.
So I decided to modify `style.css` which is styling my theme, Twenty-fifteen. (Don’t have time to back up the theme or create a child theme.) Modifying `style.css` is easy but bear in mind whenever it gets updated it gets overwritten. So you need to modify `style.css` after every update.
As you can see on my site, my article has wide area so it has more contents to offer within one screen. You can download my ‘style.css’ here: https://dl.dropboxusercontent.com/u/5055823/style.css
