27 What is HTML5? HTML5 will be the new standard for HTML, XHTML, and the HTML DOM. HTML5 is still a work in progress. However, most modern browsers have much HTML5 support. HTML5 is a cooperation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG). WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML. 27

28 HTML5 Development Rules The following rules for HTML5 were established: New features should be based on HTML, CSS, DOM, and JavaScript Reduce the need for external plugins (like Flash) More markup to replace scripting HTML5 should be device independent Browser Support HTML5 is not yet an official standard, and no browsers have full HTML5 support. But all major browsers (Safari, Chrome, Firefox, Opera, Internet Explorer) continue to add new HTML5 features to their latest versions. 28

34 Block element vs. Inline element All HTML elements are naturally displayed in one of the following ways: Block takes up the full width available, with a new line before and after (display:block;) Inline takes up only as much width as it needs, and does not force new lines (display:inline;) Not displayed Some tags, like <meta /> and <style> are not visible (display:none;) 34

35 Block Element vs. Inline Element Block Elements <div> Your general-purpose box <h1>... <h6> All headings <p> Paragraph <ul>, <ol>, <dl> Lists (unordered, ordered and definition) <li>, <dt>, <dd> List items, definition list terms, and definition list definitions <table> Tables <pre> Indicates a block of preformatted code <form> An input form <blockquote> Like an indented paragraph, meant for quoting passages of text 35

36 Block Element vs. Inline Element Inline Elements <span> Your all-purpose inline element <a> Anchor, used for links (and also to mark specific targets on a page for direct linking) HTML5 부터다른블록요소를감쌀수있게되었음. <strong> Used to make your content strong, displayed as bold in most browsers, replaces the narrower 시각적으로두꺼운글씨 + 의미적으로도강조 <bold> or <b> bold tag 시각적으로두꺼운글씨 <em> Adds emphasis, but less strong than <strong>. Usually displayed as italic text, and replaces the old <i> (italic) tag 36

37 Block Element vs. Inline Element Inline Elements <img /> Image alt attribute should be specified. <img src="p.gif" /> <img src="p.gif" alt="p" /> <br> The line-break is an odd case, as it's an inline element that forces a new line. However, as the text carries on the next line, it's not a block-level element. <input> Form input fields like and <abbr> Indicates an abbr. <acronym> Working much like the abbreviation 37
