CSS :last-of-type Selector

The :last-of-type selector is a powerful tool in CSS that allows web developers to target the last element of a specific type within its parent. Understanding how the :last-of-type selector works can significantly enhance your styling capabilities when building websites.

B. Importance of :last-of-type in CSS

B. Usage Considerations

While :last-of-type is supported widely, it’s important to ensure that your markup is semantically rich. Overuse or incorrect usage in complex layouts might lead to unintended results.
