Structure of HTML Documents

HTML documents consist of various elements, including headings which define the structure. A well-structured document is vital for SEO, as search engines prioritize content that is organized and easy to understand.

HTML Heading Tags

In HTML, there are six levels of heading tags, designed to create a clear hierarchy in your content, ranging from the most important to the least important.

h1 to h6 Tags

The heading tags extend from <h1> to <h6>, where <h1> represents the most important heading and <h6> the least important.

Definition and Purpose of Each Heading Level

Tag	Definition	Typical Use
<h1>	Main heading of the document	Title of the page
<h2>	Second-level heading	Major sections of the page
<h3>	Third-level heading	Subsections of <h2>
<h4>	Fourth-level heading	Subsections of <h3>
<h5>	Fifth-level heading	Subsections of <h4>
<h6>	Sixth-level heading	Minor subsections

The Use of Headings in HTML

Semantic Structure

Using headings appropriately gives your document a semantic structure. Search engines and assistive technologies rely on this structure to index and present your content effectively.

Accessibility Considerations

Proper use of heading tags enhances accessibility for users with disabilities. Screen readers utilize these tags to help users navigate the content, making the correct use of headings critical.

Styling Headings with CSS

Headings can be styled using CSS to enhance their appearance and visibility on the web page. Here are some basic and advanced techniques:

Basic Styling

To apply basic styles, you can use the following CSS:

h1 {
    font-size: 2.5em;
    color: navy;
}
h2 {
    font-size: 2em;
    color: darkblue;
}
h3 {
    font-size: 1.75em;
    color: steelblue;
}

Advanced Styling Techniques

Advanced techniques include using properties such as shadows, margins, and padding:

h1 {
    font-size: 2.5em;
    color: navy;
    text-shadow: 2px 2px 5px rgba(0,0,0,0.3);
    margin-bottom: 20px;
}
h2 {
    font-size: 2em;
    color: darkblue;
    border-bottom: 2px solid black;
    padding-bottom: 10px;
}
