HTML5+CSS3+Bootstrap响应式Web前端设计（慕课版） (范玉玲，段春笋，张芊茜)（Z-Library）

【One-Line Pitch】 A practical, classroom-tested path from raw HTML tags to responsive Bootstrap layouts, built around hands-on projects rather than theory. Best for beginners and vocational/self-taught learners who want one book that carries them from "what is a tag" to a working multi-device site. 【Book Arc】 - **Opening (~0%–9%)**: Frames the web page as a bundle of content types (text, images, links, audio, video) and introduces the toolchain — HTML5, CSS3, jQuery, Ajax, and Bootstrap — so readers know what each layer is for before touching code. - **Early (~9%–27%)**: Core HTML5 markup: document structure, `<meta>`, text and semantic elements, images, hyperlink types and paths, tables, forms, and new HTML5 input types. This is the "make a valid page" stage. - **Early–Middle (~27%–45%)**: CSS fundamentals — the content/presentation separation idea, selector families (element, class, ID, descendant, intersection), fonts, text, color, and background properties. Solves "how do I style what I just built." - **Middle (~45%–64%)**: The box model, margins and padding, lists, floats, positioning, and z-index stacking. This is where layout thinking begins and where most beginners slow down. - **Late (~64%–82%)**: CSS3 effects (border-image, filters, transitions, 2D/3D transforms), Flexbox sizing behavior, and media queries — the bridge from fixed layouts to responsive ones. - **Ending (~82%–100%)**: Bootstrap as the capstone: grid system, typography, tables, forms, buttons, and a full responsive site project with breakpoint-specific navigation and content behavior. 【Key Takeaways】 - **Structure, presentation, and behavior are separate concerns** (Early): HTML carries meaning, CSS carries appearance, and scripts/frameworks add interaction — the book returns to this split repeatedly. - **Semantic HTML5 elements replace generic `<div>` scaffolding** (Early): `<header>`, `<article>`, and similar tags clarify document structure but carry no default styling, so CSS still does the visual work. - **Selector choice drives maintainability** (Early–Middle): class selectors for repeated patterns, ID selectors for unique elements, and a documented cascade order from browser defaults up to inline styles. - **The box model is the real layout primitive** (Middle): width/height, padding, border, and margin — including collapsing vertical margins — explain most "why is this element here" confusion. - **Floats and positioning are powerful but leaky** (Middle): floats remove elements from normal flow and require clearing; absolute positioning escapes the document flow, while z-index resolves stacking by "larger wins, later wins." - **CSS3 adds polish without JavaScript** (Late): border-image, brightness/contrast filters, transitions, and 2D/3D transforms are covered with vendor-prefix caveats for older browsers. - **Flexbox solves proportional sizing** (Late): flex-grow and flex-shrink let items expand or contract by ratio, which fixed-width layouts cannot do. - **Media queries plus Bootstrap's 12-column grid make responsiveness systematic** (Late–Ending): breakpoints at roughly 768px, 992px, and 1200px drive layout, visibility, and content-density changes. 【Reading Tips】 - Deep-read the HTML and CSS chapters (roughly the first half); skim the jQuery/Ajax background material in the opening if you only need markup and styling. - Treat the "动手实践" (hands-on practice) blocks as mandatory — they are where form controls, table layout, and media queries actually stick. - Slow down on floats, positioning, and z-index; these are the book's hardest conceptual cluster and the source of most layout bugs. - When you reach Bootstrap, don't just copy classes — re-derive the grid rules (rows inside containers, columns as direct children of rows) so you can debug without the docs. - Keep the vendor-prefix notes for CSS3 filters and transforms as a reference, not memorization; modern browsers mostly no longer need them. 【Coverage Limits】 This guide is synthesized from stratified excerpts covering the book's full arc, but some chapters (notably the jQuery/Ajax material and later project chapters) appear only in fragments, so specific exercise details and chapter numbering are not fully reconstructed.
