I am looking to create a left nav bar like the one on the Treehouse site here: http://teamtreehouse.com/library
The main thing I am trying to replicate is the links tooltip that slides out/fades in beside the icon. Looking at the source, I believe thats done through CSS? correct me if I'm wrong.
Also, I noticed they have svg classes on the links, are they just for site responsiveness and not really related to the function of the links/tooltip?
Thanks for any help on this and please let me know if I can provide any other info.
