-DropCSS is an [exceptionally fast](#performance), thorough and tiny ([~10 KB min](https://github.com/leeoniya/dropcss/tree/master/dist/dropcss.min.js)) unused-CSS cleaner; it takes your HTML and CSS as input and returns only the used CSS as output. Its custom HTML and CSS parsers are highly optimized for the 99% use case and thus avoid the overhead of handling malformed markup or stylesheets, so you must provide well-formed input. There is minimal handling for complex escaping rules, so there will always exist cases of valid input that cannot be processed by DropCSS; for these infrequent cases, please [start a discussion](https://github.com/leeoniya/dropcss/issues).

-As a bonus, DropCSS will also remove unused `@keyframes` and `@font-face` blocks - an out-of-scope, purely intra-CSS optimization. Speaking of which, it's a good idea to run your CSS through a structural optimizer like [clean-css](https://github.com/jakubpawlowicz/clean-css), [csso](https://github.com/css/csso), [cssnano](https://github.com/cssnano/cssnano) or [crass](https://github.com/mattbasta/crass) to re-group selectors, merge redundant rules, etc. It probably makes sense to do this after DropCSS, which can leave redundant blocks, e.g. `.foo, .bar { color: red; } .bar { width: 50%; }` -> `.bar { color: red; } .bar { width: 50%; }` if `.foo` is absent from your markup.
