  • An article with a title and metadata
  • An article with a title and subtitle
  • An article with a title, subtitle and metadata
  • ...4 more annotations...
  • If you have a title with subtitle(s) and other metadata associated with the section or article, place both the <hgroup> and the metadata within a single <header> element.
  • If you have a title with subtitle(s) or tag lines (i.e., more than one consecutive <h1>–<h6>), group them in an <hgroup>.
  • When grouping headings in an <hgroup> element, the outline algorithm will mask the lowest level all but the highest level heading in the group from the resulting document outline.
  • It can only contain a group of <h1>–<h6> element(s), and it should be used for subtitles, alternative titles, and tag lines.

    In the previous article in this series, you learned about the canvas element, and the basics for drawing on it. In this article, I'm going to demonstrate some of the more advanced drawing functionality.

html5 css3 javascript video formats browser support

shared by Vernon Fowler on 05 Feb 13 - No Cached
  • The solution for now is to produce your videos in multiple formats. Table 1. Browser support by video format Browser MP4 WebM Ogg Internet Explorer 9 Yes No No Firefox 4.0 No Yes Yes Google Chrome 6 Yes Yes Yes Apple Safari 5 Yes No No Opera 10.6 No Yes Yes Note: For the latest compatibility information, always check the CanIUse website.
  • A more robust way to create the fallback is to use a JavaScript utility like Modernizr to evaluate the browser's capabilities and then dynamically write the video and source tags or embed the Flash video player using SWFObject.
  • Tip 3: The source tag should always include the "type" attribute with the correct MIME type value. You may need to add an .htaccess file to your server to define the MIME types as well. Check out the Video for everybody article for more tips on MIME types.
  • ...2 more annotations...
  • Tip 2: The video tag includes a range of parameters that you can use to configure the video. See the Mozilla article Using HTML5 audio and video for more information.
  • Tip 1: The Adobe Media Encoder does not currently export video to Ogg or WebM format. You can use the Firefogg add-on for Firefox to encode video to Ogg Theora format, or you can use Miro Video Converter to encode video to WebM or Ogg Theora format.

section html5 html element markup outline document structure

shared by Vernon Fowler on 23 Jan 14 - No Cached
  • A general rule is that the section element is appropriate only if the element’s contents would be listed explicitly in the document’s outline.
  • The theme of each section should be identified, typically by including a heading (h1-h6 element) as a child of the section element.
  • Don’t use it just as hook for styling or scripting; that’s a div
  • ...2 more annotations...
  • Don’t use it unless there is naturally a heading at the start of the section
  • As blogposts and comments are often syndicated (by being pulled into other blogs or being linked via twitter, reddit etc) they should be articles.

semantic structure headings html5

shared by Vernon Fowler on 10 Dec 12 - No Cached
  • The sectioning elements act quite literally as their name suggests: they define sections of the parent element. These sections can be thought of as child nodes whose headings fall under their parent heading, regardless of their rank.
  • Sections may contain headings of any rank, but authors are strongly encouraged to either use only h1 elements, or to use elements of the appropriate rank for the section’s nesting level.
  • For accessibility reasons, we recommend each sectioning element have a heading, even <aside> and <nav>, as shown below. If you don’t want these headings to be visible, you can always hide them with CSS.
  • ...2 more annotations...
  • It’s best if you use logical heading levels — <h1>–<h6> — at least until the new outlines are more widely supported.
  • Unfortunately, there is little support for the new outlining algorithms right now. Search engines may be experimenting with it in their crawling algorithms as you read this, but as far as we know, headings are treated just as they were before. You won’t be penalised for using them, even if you use multiple <h1>s (which have always been okay as far as the spec is concerned). Check out our HTML5 and Search Engine Optimisation article for more on search engines and HTML5.

html html5 main

shared by Vernon Fowler on 19 Jan 14 - No Cached
  • One important facet of <main> is that it can only be used once per page.
  • Another stipulation of <main> is that it can’t be used as a descendant of an <article>, <aside>, <footer>, <header>, or <nav> element.
  • Of course, if you use the html5shiv, <main> is now baked in directly.
