CSS styling of select component without JS, and using inline SVGs for the arrow symbol. The idea is to get rid of the need of using JS / JQuery for a decent select styling. Using inline SVG files to avoid extra requests to the server and a good visualization quality in retina displays. The select component is thought to be responsive by default.
The base of the idea is to remove all the default styling on the select and use a wrapping div to add out custom styling.
The easiest way of control your <select> size is using the padding property at .theme-your-theme select selector. Other customizations (font, size, color...) are made using standard CSS properties.
Please, take a look to the included demo for several samples.
