HTML Block Elements
HTML block elements are fundamental to creating the structure of a webpage. These elements cover the entire width of their parent container, thus forming a block of content.
<!-- HTML Block Elements -->
<div class="container">
<p>This is a paragraph inside a div.</p>
</div>
<h1>This is heading</h1>
<ul>
<li>a</li>
<li>b</li>
<li>c</li>
</ul>
Characteristics of Block Elements
- Occupy Full Width: Block elements take up the entire width by default.
- Start on a New Line: Each block element starts on a new line, creating a vertical stack of elements.
- Contain Other Elements: Block elements can contain other blocks or inline elements, making them flexible for content composition.
Common HTML Block Elements
Here are some of the most commonly used HTML block elements:
The <div> Element
The <div> element is a general container that groups other elements. It has no specific meaning or style by default but is highly useful for applying CSS styles or JavaScript interactions.
<div class="container">
<p>This is a paragraph inside a div.</p>
</div>
The <p> Element
The <p> element acts as a paragraph of text. It automatically adds some space before and after the text, making it easy to separate different blocks of text.
<p>This is a paragraph.</p>
The <h1> to <h6> Elements
The <h1> to <h6> elements represent headings. The <h1> is the highest heading, and <h6> is the lowest. These elements define the hierarchical structure of content.
<h1>Main Heading</h1>
<h2>Subheading</h2>
The <ul> and <ol> Elements
The <ul> element creates an unordered list (bulleted list), while the <ol> element creates an ordered list (numbered list). Both elements require list items (<li>) as children.
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
<ol>
<li>First item</li>
<li>Second item</li>
</ol>
The <blockquote> Element
The <blockquote> element is used for quoting a large section of text from another source. It often includes citation information.
<blockquote>
"This is a block quotation."
</blockquote>
The <header> and <footer> Elements
The <header> element represents introductory content or a set of navigational links. The <footer> element shows the footer for the website page or its nearest sectioning content.
<header>
<h1>Website Title</h1>
<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
</ul>
</nav>
</header>
<footer>
<p>© 2024 Company Name. All rights reserved.</p>
</footer>
The <section> and <article> Elements
The <section> element defines a section, such as a chapter or a content group. The <article> element is self-contained content that can be independently distributed or reused, such as a blog post, news story, or forum entry.
<section>
<h2>Section Title</h2>
<p>Content of the section.</p>
</section>
<article>
<h2>Article Title</h2>
<p>Content of the article.</p>

The <nav> element represents a section intended for navigation links. Users can navigate through the website with the help of <nav> element.
<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Contact</a></li>
