Terrify
Remember back in the early days of the internet when stylesheets were barely a thing and all your <body> tags had a bgcolor attribute? Now you can relive that dark time using Terrify!
But seriously... why would anyone want this? One reason: HTML emails. For some reason those got left behind in the dark ages. I want to be able to use sane stylesheets when I create HTML emails so I created this tool to take a sane, readable document and make it terrible. For example:
terrify -i page-with-block-css.html -o page-with-inline-css.html
