How to remove elements from HTML/Change the page entirely? : <p>I am using the following tag to load my scripts and start the game I am making, but all the original elements stay from the original webpage.</p>

<pre><code>&lt;input type="image" src="Images/start.jpg" height='200' width='350' alt='Something went wrong loading the images. Update your Internet plugins and try again.' onclick='INIT_THREE(); INIT_CANNON(); UPDATE();'/&gt;
</code></pre>

<p>Is there any way to remove the elements like the background sound and image when I press the button? I tried using href to load another html page, but I don't think that is the best way to do it, plus it didn't work. Any help appreciated, thanks!</p>
