hello friends,
I recently became obsessed with optimising this website for maximum speed, trying to get every file as small and minified as possible. One of the things which bugged me was having a rather bulky CSS file. This site was built using Bootstrap mainly because I like the grid system but also because there is a great mobile hamburger menu that works straight out of the box. Even though you can customise Bootstrap by downloading only the components you are going to use, you still end up with some excess CSS. To cut this out you can use a Grunt task called UnCSS which runs through your sites HTML and cuts out any unused CSS rules. The only problem is that it is rather complicated to run this task with WordPress as all the pages are created dynamically with PHP.
