Create a Web page that contains a button that when clicked toggles the visibility on and off of a div element with some content.

Do not use jQuery or any other third party library; use only the browser's native Javascript interface.

Javascript objects representing HTML elements have a style attribute that allows you to change the CSS rules applied to the element. With this you can change the visibility of an element as follows.

element.style.visibility = 'visible'; element.style.visibility = 'hidden';
