3 To be backward compatible with existing web features build on existing features and allow you to provide fallback content for is suggested to detect support for individual HTML5 features using a few lines of you are not familiar with any previous version of html , I would recommend to go through ourHTML Tutorial before you explore further concepts of - SYNTAXHTML5 - SYNTAXThe html 5 language has a "custom" html syntax that is compatible with html 4 and XHTML1documents published on the Web, but is not compatible with the more esoteric SGML features ofHTML 5 does not have the same syntax rules as XHTML where we needed lower case tag names,quoting our attributes,an attribute had to have a value and to close all empty HTML5 is coming with lots of flexibility and would support the followings Uppercase tag are optional for values are empty elements are DOCTYPEDOCTYPEs in older versions of html were longer because the html language was SGML basedand therefore required a reference to a 5 authors would use simple syntax to specify DOCTYPE as follows <!

4 DOCTYPE html >All the above syntax is EncodingHTML 5 authors can use simple syntax to specify Character Encoding as follows <meta charset="UTF-8">All the above syntax is <script> tagIt's common practice to add a type attribute with a value of "text/javascript" to script elements asfollows <script type="text/javascript" src=" "> </script> html 5 removes extra information required and you can use simply following syntax <script src=" "> </script>The <link> tagSo far you were writing <link> as follows <link rel="stylesheet" type="text/css" href=" "> html 5 removes extra information required and you can use simply following syntax <link rel="stylesheet" href=" "> HTML5 ElementsHTML5 elements are marked up using start tags and end tags. Tags are delimited using anglebrackets with the tag name in difference between start tags and end tags is that the latter includes a slash before the is the example of an HTML5 element <p>.

5 </p> HTML5 tag names are case insensitive and may be written in all uppercase or mixed case,although the most common convention is to stick with lower of the elements contain some content like <p>..</p> contains a paragraph. Some elements,however, are forbidden from containing any content at all and these are known as void example, br, hr, link and meta is a complete list of HTML5 AttributesElements may contain attributes that are used to set various properties of an attributes are defined globally and can be used on any element, while others are defined forspecific elements only. All attributes have a name and a value and look like as shown below in is the example of an HTML5 attributes which illustrates how to mark up a div elementwith an attribute named class using a value of "example" <div >..</div>Attributes may only be specified within start tags and must never be used in end attributes are case insensitive and may be written in all upper case or mixed case,although the most common convention is to stick with lower is a complete list of HTML5 DocumentThe following tags have been introduced for better structure section This tag represents a generic document or application section.

You would be able to get the values of these attributes using JavaScript APIs or CSS in similarway as you get for standard - EVENTSHTML5 - EVENTSWhen a user visit your website, they do things like click on text and images and given links, hoverover things etc. These are examples of what JavaScript calls can write our event handlers in Javascript or vbscript and you can specify these event handlersas a value of event tag attribute.
