The 108 bytes in question: @charset "UTF-8"; img,canvas,iframe,video,svg{max-width:100%} .overflow-container{overflow-y:scroll; -webkit-overflow-scrolling:touch} Analysis (EDIT): I'm not sure why the CSS needs to be declared as containing UTF-8 since all the characters of the file are part of the US-ASCII range. Use the .overflow-container on tables and pre/code blocks. "-webkit-overflow-scrolling" seems to be useful to allow horizontal scrolling on overflow elements on iOS [1]. * [1]: http://stackoverflow.com/questions/15605085/webkit-overflow-scrolling-touch-causing-vertical-scrolling-problems-on-mobil http://stackoverflow.com/questions/15605085/webkit-overflow-...
