Ok, math isn't my strong side, I admit it.
All I want to do is to select the first, 5th, 9th, 13th, 17th etc row in a html-table. Can anybody with better math-skills point me in the right directionor perhaps supply a "nth-child-for-dummies" guide?
I tried nth-child(1n+4) (which selects the 4th row and everyone after), and i also tried nth-child(0n+4) which selects the fourth row and nothing after that.
Thanks in advance.
