The idea was to handle all presentational aspects of a web page through CSS. For many years, it was considered best practice to use instead of for bold text and instead of for italics. If you need to create XML-compliant code, build your pages using an XHTML 1.0 DOCTYPE, and replace it with an HTML5 DOCTYPE just before deploying them online.Īnother change you need to make when converting to HTML5 concerns the use of bold text and italics.

Dreamweaver CS5.5 makes it easy to switch the DOCTYPE and strip out unnecessary code by choosing File > Convert > HTML5.ĭreamweaver CS5.5 doesn’t offer the option to create HTML5 pages with XHTML-style markup. It was added to XHTML solely to conform to the rules of XML. To ease the transition between XHTML 1.0 and HTML5, the closing slash is permitted, but it’s no longer required. Converting to HTML5Īs mentioned in Chapter 1, all that’s needed to convert a page to HTML5 is to replace the existing DOCTYPE declaration with the case-insensitive new one: īecause the pages in the Tozai Hotel site were created with an XHTML 1.0 Strict DOCTYPE, tags that don’t have a corresponding closing tag, such as and, have a forward slash before the closing angle bracket like this: Even if you make the radical decision to drop all support for IE 6, you should ensure that the site remains functional.
If your website’s server statistics show that IE 6 still has a significant market share, you might need to take a different approach. The syntax and functionality remain unchanged.ĭetermining how far to go in supporting a particular browser is a decision that you should make only on a case-by-case basis.
The CSS3 Selectors module refers to the adjacent sibling selector as the adjacent sibling combinator, but it’s simply a change of name. The downside is that changes to the page structure might destroy the relationship, resulting in the style rule no longer being applied. Using selectors to target elements based on their relationship to their immediate siblings avoids the need to pepper your code with classes. If any other element comes between them, the rule doesn’t apply. In other words, h1 + p tells the browser to apply the rule only to elements that immediately follow an heading.

The selector on the left of the plus sign identifies the element that must precede the element that matches the selector on the right. The adjacent sibling selector, which consists of two selectors separated by a plus sign (+), is designed precisely for this purpose. For example, you might want to apply a different style to each first paragraph that follows a heading. Sometimes it’s convenient to apply a style rule to an element only if it immediately follows another element at the same level of the document hierarchy (a sibling).

In the next chapter, I’ll show you how to adapt it for display in mobile phones and tablets through the use of media queries. In this chapter, you’ll learn how to apply progressive enhancement to a website for a fictitious hotel. Visitors using earlier browsers get a satisfactory experience when they upgrade, they automatically see the improved features. They advocate progressive enhancement-building a website that works satisfactorily in all current browsers and then adding features to improve the experience for visitors using more advanced browsers. In more recent times, leading designers have turned this idea on its head, arguing that you shouldn’t need to wait for the majority of browsers to implement a feature before using it. If a feature couldn’t be supported by a particular browser-usually Netscape 4-a fallback solution prevented the design from breaking completely.
A more enlightened approach known as graceful degradation emerged with the web standards movement in the first decade of the new century. But if you weren’t using IE-and many weren’t-it was still your hard luck. When IE eventually emerged as the victor in the browser wars, many designers breathed a sigh of relief and designed exclusively for IE. If you weren’t using the recommended browser, that was just your hard luck. Designers often gave up trying to reconcile incompatible differences between Internet Explorer (IE) and Netscape. When we treat them as if they were what they should be, we improve them as far as they can be improved.īack in the 1990s, it was common for the front page of a website to inform visitors that it was “best viewed” in a particular browser.
