# HTML Host Pages

Any HTML page containing the proper incantation can include code created with GWT, referred to as a host page. A typical HTML host page looks like this:

     <html>
      <head>

        <!-- Properties can be specified to influence deferred binding -->
        <meta name='gwt:property' content='locale=en_UK'>

        <!-- Stylesheets are optional, but useful -->
        <link rel="stylesheet" href="Calendar.css">

        <!-- Titles are optional, but useful -->
        <title>Calendar App</title>

      </head>
      <body>

        <!-- The fully-qualified module name, followed by 'nocache.js' -->
        <script language="javascript" src="com.example.cal.Calendar.nocache.js"></script>

        <!-- Include a history iframe to enable full GWT history support -->
        <!-- (the id must be exactly as shown)                           -->
        <iframe src="javascript:''" id="__gwt_historyFrame" style="width:0;height:0;border:0"></iframe>

      </body>
     </html>

The structure was designed to make it easy to add GWT functionality to existing web applications with only minor changes.
