How can I select all children of an element except the last child?

Nick Craver's solution works but you can also use this:

:nth-last-child(n+2) { /* Your code here */ }

Chris Coyier of CSS Tricks made a nice :nth tester for this.

When IE9 comes, it will be easier. A lot of the time though, you can switch the problem to one requiring :first-child and style the opposite side of the element (IE7+).

Make it simple:

You can apply your style to all the div and re-initialize the last one with :last-child:

for example in CSS:

.yourclass{
    border: 1px solid blue;
}
.yourclass:last-child{
    border: 0;
}

or in SCSS:

.yourclass{
    border: 1px solid rgba(255, 255, 255, 1);
    &:last-child{
        border: 0;
    }
}

• easy to read/remember
• fast to execute
• browser compatible (IE9+ since it's still CSS3)

You can use the negation pseudo-class :not() against the :last-child pseudo-class. Being introduced CSS Selectors Level 3, it doesn't work in IE8 or below:

:not(:last-child) { /* styles */ }
