EasyTutorGuide · Six levels · 145 connected chapters
Start from the first chapter. Learn what each idea is for, change the example yourself, then build something that proves you understand it. No previous knowledge is assumed at Level 1, but framework courses explain the essential HTML, CSS, JavaScript and tooling prerequisites before advanced work.

Read the chapter before attempting the exercise. Treat unfamiliar words as instructions to investigate, not as words you must already know. For code, enter the source exactly; confirm the output; make one change and predict how the result will change. When you see a result labeled Expected output, it must be run inside the corresponding installed framework or design tool—it is not evidence that the static HTML page executed that code.
Each course’s 145 lesson pages remain in the archive. This new handbook adds curated progression and worked code checkpoints, but it does not replace a detailed line-by-line rewrite of every existing draft chapter.
Chapters 1–24. Your goal is to move from recognizing features to independently producing reliable work.
Level project: A simple mobile profile screen. Start with a minimum working feature, add realistic test data, record a visible result, and correct at least one failure. Keep source files and a short explanation of decisions.
Read the source first; then inspect the output immediately underneath.

Complete the six level projects, write a short design decision for each, demonstrate accessibility and error handling, measure performance when appropriate, and run the code in the actual framework. Invite someone else to use the result without your help, record what failed, and improve it.
