First child will work if i use it this way: http://codepen.io/sydnej/pen/lKvhm
At first i didn’t know of using ie in this. That was second thought. And I wanted it to be in one list. Thank you. You helped me a lot!
Your idea is very good for me in ‘normal’ browsers and mine is one that i will use for example in cross browser mixins for css ie7 style. :)
