$("html tags"):generate code with the jQuery wrapper function.

Pass in a string to the jQuery function like so:

$("<p>My paragraph</p>");

You need an additional jQuery method like .appendTo() in order to insert the new markup into the DOM.

The following code sample shows HTML generation, coupled with .appendTo() and .attr() used to insert a new H1 into the page.

 
<!DOCTYPE html>
<html>
    <head>
        <style type="text/css">
        .titleText {
            color: green;
            font-family:arial;
        }
        </style>
        <script src="http://java2s.com/Book/JavaScriptDemo/jQuery/jquery-1.8.0.min.js"></script>
        <script>
            $(function(){
                $("<h1>This is a header</h1>")
                .appendTo("body")
                .attr("class", "titleText");
            });

        </script>
    </head>
    <body>
    </body>
</html>
