This package post-processes HTML files and injects CSS and adds tags to create some further customization (for example highlight cells of a HTML table). This is most useful when writing a document using markdown and converting it into a HTML document using a tool like knitr, slidify, or...

They seemed to go over pretty well in my interviews and helped me greatly as I did not need to remember or write down specific numbers to talk about.
