Semantic HTML: Give a Web Page Meaningful Structure

Outline the document first

Write the page content in a logical order before adding layout rules. Identify the main topic and supporting sections. Use headings to communicate those relationships rather than choosing them only for their default size. Visual appearance can be adjusted later without weakening the content structure.

Choose elements by purpose

Use links for navigation and buttons for actions on the current page. Group navigation and main content with suitable landmarks. Not every visual container needs a semantic section. Choose an element because it describes the content or behaviour, then use neutral containers where no stronger meaning is needed.

Make forms understandable

Associate labels with their inputs, give controls appropriate names, and explain the expected information. Group related choices where useful. Show validation feedback near the field and explain how to fix it. Test the form with keyboard input instead of assuming that correct appearance guarantees usable behaviour.

Review the unstyled page

Temporarily remove CSS and read the document from top to bottom. The information should still make sense, and links should still explain where they go. Validate the markup and inspect repeated identifiers. This simple exercise exposes structural problems that a polished layout can otherwise conceal.
