HTML5 Browser Support:
HTML5 is supported in all modern browsers.
In all browsers, unrecognized elements are automatically handled as inline elements.
There might be a problem with some old browsers like Internat Explorer 6,7,8 which may not open the web page properly.
You can instruct older browsers to handle “unknown” HTML elements.
Define Semantic Elements as Block Elements:
The semantic elements defined by HTML5 are all block-level elements.
To fix the correct behavior of these elements in older browsers, you can set CSS display property for these elements to block.
Add New Elements to HTML:
New elements can be added to an HTML page using a browser trick.
In this example, a new element is added called <demo> to an HTML page and defines the style for it.
The document.createElement(“demo”) JavaScript statement is needed to create a new element in IE 9, and earlier.
