Block display behavior is a fundamental concept in CSS that determines how elements are rendered on a web page. Understanding block elements is crucial for any frontend developer, as it affects layout, spacing, and overall design.

<h1>Welcome to My Website</h1>
<p>This is a paragraph of text that describes the content of the website.</p>
<div class="box">
<p>This is a nested block element.</p>
</div>
</div>
