HTML gives a page its structure and meaning. CSS shapes its presentation, and JavaScript can add interactive behavior. These roles work together while remaining useful to distinguish.

A heading is more than larger text. It describes a section and helps readers and assistive technology understand the document. A button is more than a colored rectangle; it represents an action.

A well-built page remains clear as its presentation changes. Begin with meaningful structure, then use style and interaction to support what the page is for.

A small working example.

A recipe can remain understandable when its decorative styling is absent. Headings, lists, and paragraphs preserve the relationship between ingredients and instructions.

A note to keep beside it.

Read the page as a sequence of decisions. Each heading, link, and control should explain where you are and what a sensible next step might be.
A few starting points
  1. Notice the heading hierarchy.
  2. Distinguish navigation from an action.
  3. Try the page with a different text size.
