The LastChild field of the PseudoClass enum represents the CSS pseudo-class :last-child. This pseudo-class is used to select the last element among a group of sibling elements. It is useful in styling scenarios where you want to apply specific styles to the last child element of a parent.
Use the LastChild pseudo-class when you need to apply styles specifically to the last child element within a parent container. This can be particularly useful for UI elements where the last item needs distinct styling, such as removing a border or adding extra padding.
// Example of using the LastChild pseudo-class in a UI component
var myElement = new Panel();
myElement.StyleSheet = @"
.my-container :last-child {
border-bottom: none;
padding-bottom: 20px;
}
";
// Assuming myElement is part of a container with multiple children,
// the last child will have no bottom border and extra padding at the bottom.
