HTML - how to make an entire DIV a hyperlink? [duplicate]

You can add the onclick for JavaScript into the div.

<div onclick="location.href='newurl.html';">&nbsp;</div>

EDIT: for new window

<div onclick="window.open('newurl.html','mywindow');" style="cursor: pointer;">&nbsp;</div>

You can put an <a> element inside the <div> and set it to display: block and height: 100%.
