How to Select All Children of an Element Except the Last Child

The CSS3 selector :last-child allows developers to target an element that is the last child in its container. However, there might be instances when you need to select all children of an element except the last one.

Using the negation pseudo-class :not() in conjunction with :last-child, we can achieve the desired result. This selector will match all elements that are not the last child in the selected container.

:not(:last-child) {
  /* Styles for all children except the last */
}

This technique is particularly useful for applying different styles to all child elements except the last one. For instance, in a list, you could add a bottom border to all list items except the final one to create a visually appealing effect.

Note that the combination of :not() and :last-child is part of CSS Selectors Level 3 and may not be supported in older browsers like Internet Explorer 8 and below. However, it offers a versatile solution for selecting all but the last child of an element in modern browsers.
