Css Multiple background-color
- by Khanh TO
I'm a novice in Css and it's difficult to search for this specific case on the internet, so I post a question here.
I'm working on an existing code base and I see something like this.
li {
background-color: #000 \9;
background-color: rgba(0, 0, 0, 0);
}
I don't understand the meaning of \9. But it looks to me they are duplicates and I should remove one of them.
Could you please explain the \9 and should I remove one of them? Thanks.
