Web Fundamentals

Turning HTML meaning, CSS presentation, JavaScript behaviour and accessibility into a small working web product.

Completion evidence: Semantic HTML, responsive CSS, keyboard test, error behaviour and user feedback.

Build a small page with a form; test labels, keyboard order, mobile overflow and invalid-input messages separately.

The order is recommended. Before a project page, complete evidence from foundation, practice and debugging lessons.

Turning HTML meaning, CSS presentation, JavaScript behaviour and accessibility into a small working web product. A correct example alone is therefore insufficient. Completion evidence should be semantic html, responsive css, keyboard test, error behaviour and user feedback, tested with normal, boundary and invalid inputs.

In the first cycle, pair foundation and application among Visual Layout with CSS, The DOM and Interaction, Accessibility Basics, Forms and Data Safety, Page Skeleton with HTML. Predict the result, run or measure it, then explain any difference. Even when prediction and reality match, state which changed condition would break the result.

In the second cycle, complete this laboratory: Build a small page with a form; test labels, keyboard order, mobile overflow and invalid-input messages separately. Do not close with one successful screenshot. Keep the input table, expected behaviour, actual behaviour, error or measurement and the correction in one file.

In the final cycle, connect How the Internet and the Web Work, Introduction to JavaScript, Project: Personal Project Page, Responsive Design, Semantic HTML. Let one lesson's output become another lesson's input; show where safe stopping is needed when data type, unit, wiring, timing or user expectation changes.

Repeat the same task one month later with less source support. Compare not only speed or appearance but test coverage, explainability, safety and whether another person can rebuild the work.

Use the foundation produced in Visual Layout with CSS as an input to How the Internet and the Web Work. Then show in Semantic HTML how the same idea changes under the limits of a larger system. This bridge carries the goal of turning html meaning, css presentation, javascript behaviour and accessibility into a small working web product. beyond one isolated example.

Add three columns to the semantic html, responsive css, keyboard test, error behaviour and user feedback file: knowledge carried from the previous lesson, condition changed in the new lesson and result observed in testing. Sharing a word does not establish a connection; one lesson’s output should genuinely become the next process’s input.

Test the connection through this laboratory: Build a small page with a form; test labels, keyboard order, mobile overflow and invalid-input messages separately. After the first attempt, add an edge condition such as empty data, wrong type, disconnected input, extreme value or user error. Record whether the system remains understandable and safe beyond the normal example.

• Name the previous lesson output
• State the one changed condition
• Separate expected and actual result
• Define safe stopping or error feedback
• Make one change in the second version
