Recently Shamley Incorporated received a client request for a new feature that required a 5 column layout. We have been using Bootstrap 3.x for this site which makes most layouts very easy, however there is no way to make it work for 5 even columns. Luckily it is pretty simple to add your own Bootstrap layouts, the below code pattern will give you a nice feature set for building your 5 column layout with the options shown in the image.
<iFrame> or even (GASP) use a Flash plugin to make it work. Not anymore!
