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

How would I select all but the last child using CSS3 selectors?

For example, to get only the last child would be div:nth-last-child(1).

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 */ }

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)

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+).

Using nick craver's solution with selectivizr allows for a cross browser solution (IE6+)

.nav-menu li:not(:last-child){
    // write some style here
}

this code should apply the style to all

except the last child

to find elements from last, use

<style>
ul li:nth-last-of-type(3n){ color:#a94442}  /**/
</style>

Nick Craver's solution gave me what I needed but to make it explicit for those using CSS-in-JS:

const styles = {
  yourClass: {
    /* Styles for all elements with this class */
    '&:not(:last-child)': {
      /* Styles for all EXCEPT the last element with this class */
    },
  },
};

There is a:not selector in css3. Use :not() with :last-child inside to select all children except last one. For example, to select all li in ul except last li, use following code.

ul li:not(:last-child){   }

If you're using it within the nesting of the parent then the easiest way is:

&:not(:last-child){
  ....
}

Example:

.row {  //parent
 ...
 ...
 ...
 &:not(:last-child){
  ....
 }
}
