How do I stop this border from altering my image position?

I have three square images on the top left of my webpage. When I hover over each one, I get a white border, which is good, but I noticed that the border pushes the image to the right when I hover over it. How do I prevent that?

In the W3C box model http://www.w3.org/TR/CSS2/box.html , borders along with padding and margins are on the outside of the content box.  If you add a border, it increases the size of the element.  If you want your box to not move, make the 'normal' image have a border the same color as the background and change the color when you mouseover it.

Also, your page does not have a proper DOCTYPE which means it will render in 'Quirks' mode and not 'Standards' mode.  In IE this means that a number of things do not work properly.  Also, when you add the DOCTYPE, it must be the very first thing on the page or IE will ignore it.  No comments or anything else are allowed before the DOCTYPE.  http://www.w3.org/QA/2002/04/valid-dtd-list.html

you can put in a div tag and position it using ABSOLUTE attribute

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Since your background color is changeable, giving them a border to match the background may be complicated. You could give them a transparent border the same width as the white border.
border: solid 1px transparent;

Ok I added a transparent 1px border to each and that border now turns white when I hover over it, but is there a way I can keep that border white once it is selected? I tried this and it didn't remain white once selected:

#purpleSquare:hover{border-color: #FFFFFF;}
#purpleSquare:active{border-color: #FFFFFF;}
#blueSquare:hover{border-color: #FFFFFF;}
#blueSquare:active{border-color: #FFFFFF;}
#redSquare:hover{border-color: #FFFFFF;}
#redSquare:active{border-color: #FFFFFF;}

'active' is only good for the time that you have the mouse button down.  Nothing more.  If you want to change the border color on click, you have to use javascript.  Info and examples here: http://www.w3schools.com/jsref/prop_style_bordercolor.asp

And a:active isn't supported by old browsers. I recommend using Javascript or Server-side code (like in a session or website cookie) to make the link active. Because when you refresh the page the link will be normal instead of active state.

Made a basic Javascript example for you, it adds a active class to the clicked link and is also cross-browser compatible:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Active link</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<style type="text/css">
.menu .active {
	color:#ff0000;
}
</style>
</head>

<body>
<ul class="menu">
  <li><a href="#">Link 1</a></li>
  <li><a href="#">Link 2</a></li>
</ul>
<script type="text/javascript">
$('.menu a').click(function(){
  $('.menu a').removeClass('active');
  $(this).toggleClass('active');
});
</script>
</body>
</html>

Ok one more question, I figured out a workaround to get the selected color to have a white border. But once I select a color, the hover feature doesn't seem to work. Try for yourself below. Do you know why?

For some reason, the jQuery is writing the border value a different way that is over-riding the 'hover'.  You can see it in Firebug.  

And <input> and <select> tags do not have 'innerHTML'.  Only elements that have start and end tags like <p> </p> have 'innerHTML'.
