I’m customizing a theme with a “sidebar” along the bottom of the page, and I want the widgets there to have flexible widths depending on how many widgets are published to the sidebar. So if there are 4 widgets, the before_widget output will be <div style=”width: 25%”>, if there are 3 widgets <div style=”width: 25%”>, etc. Of course, this would be very easy to to with tables, but tables are the devil now, right?
