background color every other row in SASS

Question

I'm using Ruby on Rails. I have a .sass file for a datagrid. I'd like every other row to have a different colored background.

I tried this:

tr:nth-child(2n+1) 
    background-color: #E3E3E3   

What should it be?

Thanks

Answer 1

This is generally what's used to every-other items:

tr:nth-of-type(odd) {
  background-color:#E3E3E3;
}

Answer 2

For me that works:

[hauleth@NIUNIOBOOK] ~ $ sass
tr:nth-child(2n+1) 
    background-color: #E3E3E3
^D
tr:nth-child(2n+1) {
  background-color: #e3e3e3; }

So what do you wanna get other?
