Why Isn't My :last-child Selector Working?

Understanding :last-child

The CSS selector :last-child is designed to target the last child element of a parent. In the given code sample, you have applied the selector to elements with the "complete" class. However, the problem arises when the parent element contains additional elements that are not targeted by the selector.

The Issue

In the provided HTML, the

element with the "complete" class is not the very last element in the parent

element. This means that the :last-child selector will not apply to it.

Alternative Solutions

To solve this issue, you can try alternative selectors:

• :last-of-type: This selector will target the last element of a specific type within a parent. In this case, it would select the last
• element with the "complete" class.
• jQuery $("li.complete").last();": This jQuery expression will select the last element that matches the "li.complete" selector. It is an effective way to target the desired element when you have multiple elements with the same class.

Understanding the Behavior

It's crucial to remember that :last-child will not select an element if it is not the very last element in its parent container. In other words, if there are any other elements after the targeted element, :last-child will not apply. This behavior differs from :last-of-type, which targets the last element of a specific type regardless of its position within the parent.

Conclusion

When using :last-child, ensure that the targeted element is the very last child in its parent container. If not, consider using alternative selectors like :last-of-type or jQuery expressions to achieve the desired result.
