HTML Accessibility
🎯 한 줄 통찰 (One-line insight)
Always write HTML with accessibility in mind — use semantic elements for their intended purpose so all users get a good way to navigate and interact with your site. [S1]
🧠 핵심 개념 (Core concepts)
- Accessibility-first mindset — always write HTML code with accessibility in mind, giving users a good way to navigate and interact with the site. [S1]
- Semantic HTML — use the correct HTML element for its purpose; a semantic
<button>carries suitable default styling, screen-reader recognition, focusability, and keyboard navigation that a<div>does not. [S1] - Headings convey structure — use headings (
<h1>–<h6>) for headings only, not to make text big or bold. [S1] - Alternative text — provide descriptive
alttext for images. [S1] - Declare the language — set the page language with the
langattribute on<html>. [S1] - Meaningful link text — links should describe where they lead, not say "Click here" or "Read more.." [S1]
🧩 추출된 패턴 (Extracted patterns)
- Semantic vs non-semantic — non-semantic elements:
<div>,<span>; semantic elements:<form>,<table>,<article>(and<button>). [S1] - Right element for the job — prefer
<button>Report an Error</button>over<div>Report an Error</div>. [S1] - Heading hierarchy — order headings
<h1>→<h6>to express document structure. [S1] alton every meaningful image —<img ... alt="descriptive text">. [S1]
📖 세부 내용 (Details)
Write with accessibility in mind Always write HTML code with accessibility in mind. Provide the user a good way to navigate and interact with your site. [S1]
Use semantic HTML
Use the correct HTML element for the correct purpose. For example, a button should be a <button>, not a <div>: [S1]
<button>Report an Error</button>
rather than the non-semantic:
<div>Report an Error</div>
Benefits of using the semantic <button> include suitable default styling, screen reader recognition, focusability, and keyboard navigation support. Non-semantic elements include <div> and <span>; semantic elements include <form>, <table>, and <article>. [S1]
Use headings for structure Use HTML headings for headings only. Don't use headings to make text BIG or bold. [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>
Provide alternative text for images
<img src="img_chania.jpg" alt="A narrow city street with flowers in Chania">
Declare the page language
<!DOCTYPE html>
<html lang="en">
<body>
...
</body>
</html>
Use meaningful link text Good links use descriptive text explaining where the link leads; bad links use generic text like "Click here" or "Read more..". [S1]
🛠️ 적용 사례 (Applied in summary)
The applied guidance is concrete: replace non-semantic <div> buttons with <button>, keep headings hierarchical and reserved for structure, add descriptive alt text, declare lang, and write meaningful link text. No external project/commit applications found in the source.
💻 코드 패턴 (Code patterns)
Semantic button (HTML):
<button>Report an Error</button>
Image with alternative text (HTML):
<img src="img_chania.jpg" alt="A narrow city street with flowers in Chania">
Document language declaration (HTML):
<html lang="en">

No contradictions found in the source. Note this page does not cover ARIA attributes, <label for> form-input labels, tabindex, or color-contrast requirements — those topics are not addressed here (Not found in source). [S1]
