How do I select every other div class element using just CSS (no js)

.item:nth-child(even) {...}
.item:nth-child(odd) {...}

You want nth-child() on .item.

.item:nth-child(odd) .description {
    background-color: red;
}

Maybe it's possible when we use this:

.item:nth-of-type(odd)  .description{background-color:orange;}  

or

.item:nth-child(odd) .description{background-color:orange;}

I hope you get what you need.
