Discussion on: What CSS tip do you want to share with others?

[Jeferson Brito]

I like this one:

ul {
  counter-reset: counter;
}

li:before {
  counter-increment: counter;
  content: counters(counter, '.') ' ';
}

to increment each item you add to a ul list automatically and it also supports nested lists.

and this one

.breadcrumb a:first-child::before {
    content: " » ";
}
.breadcrumb a::after {
    content: " /";
}
.breadcrumb a:last-child::after {
    content: "";
}

to easily create breadcrumb navigation
