HTML Headings
🎯 한 줄 통찰 (One-line insight)
HTML headings <h1>–<h6> express the importance and structure of content (not merely its size), with <h1> most important and <h6> least. [S1]
🧠 핵심 개념 (Core concepts)
- Six heading levels —
<h1>through<h6>. [S1] - Importance, not size —
<h1>defines the most important heading;<h6>the least important. [S1] - Browsers add margins — browsers automatically add some white space (a margin) before and after a heading. [S1]
- Headings are for structure — search engines use headings to index the structure and content of web pages; users skim them to grasp a page. [S1]
- Size is styled with CSS — use the
styleattribute withfont-sizeto change a heading's rendered size. [S1]
🧩 추출된 패턴 (Extracted patterns)
- One
<h1>per page — use<h1>for the main title (or logo). [S1] - Logical hierarchy —
<h1>for page title →<h2>for section titles →<h3>for subsections, in order. [S1] - Don't misuse headings for visuals — do not use headings just to make text big or bold; use CSS for that. [S1]
- Resize via inline style —
<h1 style="font-size:60px;">…</h1>. [S1]
📖 세부 내용 (Details)
HTML Headings
HTML headings are titles or subtitles that you want to display on a webpage. They are defined with the <h1> to <h6> tags. <h1> defines the most important heading; <h6> defines the least important heading: [S1]
<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>
Note: Browsers automatically add some white space (a margin) before and after a heading. [S1]
Headings Are Important
Headings are important. Search engines use the headings to index the structure and content of your web pages. Users often skim a page by its headings; it is important to use headings to show the document structure. <h1> headings should be used for main headings, followed by <h2> headings, then the less important <h3>, and so on. [S1]
Note: Use HTML headings for headings only. Don't use headings to make text BIG or bold. [S1]
Bigger Headings
Each HTML heading has a default size. However, you can specify the size for any heading with the style attribute, using the CSS font-size property: [S1]
<h1 style="font-size:60px;">Heading 1</h1>
Heading reference table
| Tag | Description |
|---|---|
<html> |
Defines the root of an HTML document |
<body> |
Defines the document's body |
<h1> to <h6> |
Defines HTML headings |
🛠️ 적용 사례 (Applied in summary)
A typical applied structure (e.g. a travel guide) uses <h1> for the page title, <h2> for region/section titles, and <h3> for country/subsection titles — demonstrating heading hierarchy as document outline. No external project/commit applications found in the source.
💻 코드 패턴 (Code patterns)
All six heading levels (HTML):
<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>
Resizing a heading with inline CSS:
<h1 style="font-size:60px;">Heading 1</h1>
⚖️ 모순 및 업데이트 (Contradictions & updates)
The source stresses semantics over appearance: headings should encode document structure for search engines and users, not be repurposed to make text big or bold — use CSS font-size instead. [S1]
