I've been looking for tools that minify HTML, CSS and JS together. With that being said, I don't mean just whitespace and comment removal, but also shortening of selectors.
For example
<div class="wrapper">
<div class="sub-header"></div>
</div>
to:
<div class="eD"><div class="qw"></div></div>
But haven't found any. And that is sort of backed up by the fact viewing source of popular sites like GitHub, Reddit and even Facebook reveals full class names like "main-container" etc.
So is there any tool that does what I want?
