Accessible, Discoverable HTML
Finish a production page with keyboard access, metadata, and search-friendly structure.
Accessibility and search visibility begin with the same foundation: useful text, semantic structure, descriptive metadata, and links that make sense.
Build for keyboard and screen readers
Use native controls, keep focus visible, and make the DOM order match the reading order. Add a skip link before repeated navigation.
<a class="skip-link" href="#main">Skip to content</a>
<header>...</header>
<main id="main" tabindex="-1">...</main>
Headings should form a logical outline. Images need appropriate alternatives. Form errors should be written in text and connected to the affected control.
Essential metadata
<head>
<title>HTML course · Arcbyte</title>
<meta name="description" content="Learn modern, accessible HTML in eight practical lessons." />
<link rel="canonical" href="https://example.com/courses/html" />
<meta property="og:title" content="HTML course · Arcbyte" />
<meta property="og:description" content="Build meaningful pages from the first tag to production." />
<meta property="og:image" content="https://example.com/course-card.png" />
</head>
Each public page should have a unique title and description. A canonical URL identifies the preferred address when the same content can appear at several URLs. Social metadata controls the preview when a page is shared.
Check before shipping
- Navigate the page with only a keyboard.
- Zoom to 200% and check that content remains usable.
- Confirm headings, landmarks, labels, and alternative text.
- Validate HTML and inspect the browser console.
- Test the title, description, canonical URL, and social preview.
- Measure image sizes and page performance.
Keep this
Production HTML is valid, semantic, keyboard-friendly, descriptive, and fast. Accessibility and SEO are ongoing quality practices, not final-step decorations.
