Trying to have 2 buttons, one to add a border, one to remove the border when they're clicked. This is what I have so far, not sure where to go from here, would appreciate help.
<!doctype html>
<!-- mystery3.html -->
<!-- This page changes an image source on button clicks. -->

border-width: 4px;
}
</style>

<img id="mysteryImg" src="http://upload.wikimedia.org/wikipedia/commons/f/f9/Giraffe_Portrait,_Woburn_Safari_Park.jpg" width="20%" height="20%"class="border-style1">

<input type="button" value="Show Border"
