I like the CSS only solutions. Very often I need to select a specific DOM element. Sure I could add a new class, but it is always nice if I can do that inside my stylesheets. It just looks better and keeps my HTML markup clean. first-child, last-child and nth-child are made exactly for this purpose.
AbsurdJS became one of my favorite projects. I spent a good amount of time developing it and it's getting more and more interesting. I also received some positive feedback, so I think it is time to write a bit more about the module and explain how it actually works and what exactly is made for.
