Bootstrap css use only glyphicons

Question

We have a project in late development stage. It has its own css files, with many, many classes and what not in it. Original developer of that css is not available any more.<

Answer 1

Simply go to Bootstrap's Customization page at http://getbootstrap.com/customize and untick everything apart from Glyphicons. This will give you a ZIP folder with everything you need for the Glyphicons and nothing more.
