Both CSS classes and IDs are essential for targeting specific elements and applying custom styles or behavior to them. Classes provide flexibility for styling groups of elements, while IDs allow for precise targeting of individual elements within a page. It's important to use them appropriately and adhere to best practices to maintain a well-structured and maintainable codebase.

<p class="highlight">This is a paragraph.</p>
<p class="highlight">This is another paragraph.</p>
