Hey, thanks so much for contributing! The file you edited is the outputted code for the documentation, but you have to edit the source code as well. The docs team is working on improving this, but for now you need to edit
https://github.com/tachyons-css/tachyons-css.github.io/blob/master/src/templates/index.html manually (and run npm run doc to regenerate the pages, but you’ve already made those edits).

Thanks again!
