It contains more than 350 design patterns you can put to use right away. Each design pattern is modular and cust

10、omizable, and you can combine patterns to create an unlimited number of designs. Each design pattern has been thoroughly tested and proven to work in all major web browsers including Chrome, Firefox, Internet Explorer, Opera, and Safari. All the content in this book is usable and practical. You wont

11、 waste time reading about things that dont work! With this book, you will no longer have to use hacks, tricks, endless testing, and constant tweaking in multiple browsers to get something to work. Using a design pattern is as easy as copying and pasting it into your code and tweaking a few values. Y

12、ou will immediately see which values you can modify and how they affect the result so you can create the exact style and layout you wantwithout worrying whether it will work. This is more than a cookbook. It systematically covers several usable features of CSS and combines these features with HTML t

13、o create reusable patterns. Each pattern has an intuitive name to make it easy to find, remember, and talk about. Accessibility and best practices are carefully engineered into each design pattern, example, and source code. You can read straight through the book, use it as a reference, and use it to

14、 find solutions. Each example includes a screenshot and all relevant HTML and CSS code so you can easily see how each design pattern works. The explanation for each design pattern is included alongside, so you can easily study the example while you read about how it works. Design patterns are organi

15、zed by topic, and all usable CSS rules are covered in depth and in context like no other book. All design patterns are accessible and follow best practices, making this book a worthwhile read from cover to cover, as well as an excellent reference to keep by your side while you are designing and codi

16、ng. This book unleashes your productivity and creativity in web design and development. Design patterns are like Legosyou can combine them in countless ways to create any design. They are like tools in a toolbox, and this book arms you with hundreds of tools you can whip out to solve problems quickl

17、y and reliably. Instead of hacking away at a solution, this book shows you how to create designs predictablyby combining predictable patterns. Audience This book is written for those who have some familiarity with CSS and HTML. It is for newcomers who have previously read an introductory book on CSS

18、 and HTML. It is for designers and developers who tried CSS at one time and gave up because it never seemed to work right. It is for professionals who want to take their CSS skills to a higher level. It is for all who want to create designs quickly without hacking around until they find something th

19、at works in all browsers. We assume that you know the basics of coding CSS and HTML. If you work exclusively in WYSIWYG designers like Dreamweaver or FrontPage and never look at HTML or CSS code, you may find the code in this book overwhelming. INTRODUCTION xviii If you like to learn by example, lik

20、e to see how code works, and have some familiarity with CSS and HTML, you will love this book. Some design patterns use JavaScript. To fully understand them, you need to understand the basics of JavaScript, but you do not need to know JavaScript to use these patterns. Most importantly, you do not ne

21、ed to know anything about JavaScript to understand and use the remaining 340+ design patterns because they have nothing to do with JavaScript! Innovations This book contains several innovative concepts, terms, and approaches. These are not new or radical: the technology is already built into the maj

22、or browsers, the concepts are implied in the CSS specification, and the terms are commonly used. What makes them innovative is how we define and use them to show what can be done with CSS and HTML. In other words, they are innovative because they simplify learning, understanding, and using CSS and H

23、TML. These ideas change how you think about CSS and HTML, and that makes all the difference. Furthermore, many of the design patterns in the book are innovative because they document combinations of properties and elements to solve difficult problems like never before. Six Box Models One innovation

24、in the book is the idea that CSS has six box models instead of one. CSS officially has one box model that defines a common set of properties and behaviors. A single box model is a very useful concept, but it is oversimplified. Over the years, we learned the hard way that box model properties work di

25、fferently depending on the type of box. This is one reason why so many people struggle with CSS. The box model seems simple, yet when one uses a box model property, such as width, it works only some of the time or may work differently than expected. For example, the width property sets the interior

26、width of a block box, but on table boxes it sets the outer width of the border, and on inline boxes it does absolutely nothing. Rather than treating different behaviors as an exception to one very complicated box model, we define six simple box models that specify the behavior for each type of box.

27、Chapter 4 presents the six box models, which are inline, inline-block, block, table, absolute, and float. Since you always know which of these six box models you are using, you always know how each box model property will behave. Furthermore, each box model defines its own way that it flows or is po

28、sitioned. For example, inline boxes flow horizontally and wrap across lines. Block boxes flow vertically. Tables flow their cells in columns and rows. Floats flow horizontally, wrap below other floats, and push inline boxes and tables out of the way. Absolute and fixed boxes do not flow; instead, th

29、ey are removed from the flow and are positioned relative to their closest positioned ancestor. Box Model Extents Another innovation in the book is the concept that there are three ways a box can be dimensioned: it can be sized, shrinkwrapped, or stretched (see Chapter 5). Each type of box requires d

30、ifferent combinations of properties and property values for it to be sized, shrinkwrapped, or stretched. Various design patterns in Chapters 5 through 9 show how this is done. These three terms are not official CSS terms, but they are implied in the CSS specification in its formulas and where it men

31、tions “size,” “shrink-to-fit,” and “stretch.”1 1 In the CSS 2.1 specification, the terms “size” and “sized” occur 15 times in Chapters 8, 9, 10, 11, 17, and 18. These occurrences refer to the general sense that a box has size. INTRODUCTION xviii Of course, sizing, shrinkwrapping, and stretching are

32、not new ideas. What is innovative is that this book clearly defines these three terms and shows how they are a foundational feature of CSS and a key generator of CSS design patterns. Box Model Placement Another innovation is the idea that there are three ways a box can be placed in relation to its c

33、ontainer or its siblings: specifically, it can be indented (or outdented), offset from its siblings, or aligned and offset from its container (see Chapter 8). The CSS specification talks much about offsetting positioned elements, and it talks a little about aligning elements (see Chapter 9 of the CS

34、S 2.1 specification), but it does not discuss how elements can be indented, although this behavior is implied in its formulas. Indenting, offsetting, and aligning are different behaviors. For example, an indented box is stretched and its margins shrink its width, whereas an aligned box is sized or s

35、hrinkwrapped and its margins do not shrink its width. Aligned and indented boxes are aligned to their containers, whereas offset boxes can be offset from their container or offset from their siblings. Different combinations of properties and property values are needed to indent, offset, and align di

36、fferent types of boxes. The design patterns in Chapters 8 and 9 show how this is done. Of course, indenting, offsetting, and aligning are not new ideas. What is innovative is that this book clearly defines these three terms and shows how they are a foundational feature of CSS and a key generator of

37、CSS design patterns. Column Layouts Another innovation is the discovery, naming, and documenting of 12 automated techniques built into browsers for laying out columns in tables (see Chapter 16). All the major browsers include these powerful column layout features. They are compatible across the majo

38、r browsers and are very reliable. Even though using tables for page layout is not recommended,2 tabular data still needs to be laid out, and you can take advantage of these column layouts to make tabular data look great. Fluid Layouts Another innovation is fluid layouts (see Chapter 17). The concept

39、 of fluid layouts is not new, but the process of creating them is commonly one of trial and error. In Chapter 17, we present four simple design patterns you can use to create complex fluid layouts with confidence and predictability in all major browsers. The terms “shrink” and “shrink-to-fit” occur

40、nine times in Chapters 9 and 10 of the CSS 2.1 specification. The idea that different boxes can shrinkwrap to fit their content is implied in Sections 10.3.5 through 10.3.9 and Section 17.5.2. The terms “stretch” and “stretched” occur four times in Chapters 9 and 16. The idea of stretching a box to

41、its container is mentioned in passing as shown in the following quote (italics added), “many box positions and sizes are calculated with respect to the edges of a rectangular box called a containing block.” (See Sections 9.1.2, 9.3.1, and 10.1.) 2 Using tables for layout creates accessibility issues

42、 for nonsighted users. Furthermore, fluid layout techniques (as shown in Chapter 17) are completely accessible and much more adaptable than tables. INTRODUCTION xixi These design patterns, Outside-In Box, Floating Section, Float Divider, and Fluid Layout, use floats and percentage widths to make the

43、m fluid, but they do so without the problems you normally encounter using these techniques, such as collapsed containers, staggered floats, and percentages that push floats below each other.3 The Fluid Layout design pattern creates columnar layouts with the versatility of tables but without using ta

44、bles. Even better than tables, these layouts automatically adjust their width and reflow from columns into rows as needed to fit into narrow displays. Event Styling Another innovation is the Event Styling JavaScript Framework presented in Chapter 17. This is a simple, powerful, open source framework

45、 for dynamically and interactively styling a document. It uses the latest best practices to ensure that HTML markup is completely free of JavaScript code and completely accessible, and all styling is done with CSS. Furthermore, the framework allows you to select elements in JavaScript using the same

46、 selectors you use to select elements in CSS. This vastly simplifies and unifies the styling and scripting of a dynamic HTML document! The book includes this framework to show how to integrate JavaScript, CSS, and HTML so you can use styles interactively. Of course, if you do not want to use JavaScr

47、ipt, you can skip over the five JavaScript design patterns in Chapter 17 and the two JavaScript patterns in Chapter 20the remaining 343+ design patterns do not use JavaScript. Combining HTML5 and CSS3 to Create Design Patterns The final and most pervasive innovation in the book is the idea of combin

48、ing general types of HTML elements with CSS properties to create design patterns. The book defines four major types of HTML elements in Chapter 2 (structural block, terminal block, multi-purpose block, and inline), and Chapter 4 maps them to the six box models (inline, inline-block, block, table, ab

49、solute, and float). Each design pattern specifies how it applies to types of HTML elements. In other words, a design pattern is more than a recipe that works only when you use specific elements; it is a pattern that applies to all equivalent types of HTML elements. For example, the Floating Drop Cap

50、 design pattern in Chapter 18 specifies a pattern that uses block and inline elements, but it does not specify which block and inline elements you have to use (see Listing 1). For example, you could use a paragraph for the BLOCK element and a span for the INLINE element (see Listing 2), or you could
