Highlighting required attributes when not selected.

Hello, could someone let me know if what I’m looking to do (below) is as easy as a selection in the admin area or do I have to do some hacking of the theme or something else? I’ve searched for this and it seams like something that would have been discussed already but I couldn’t find it anywhere. Sorry, I’m a knob.

I’m currently evaluating 1.3.7 with Red Passion theme. The link to where the cart is here http://180out.com/yen/ .

1. I have some required item attributes set up for the jacket and other items and they work pretty well. When a required attribute is not selected you get the warning near the top of the page. My client would also like the missed items highlighted some how in red. Can this be done?
2. If you view the ‘Skull Cap” product you will notice that I have the different color hats set up as attributes. Is there a way to get these hat attributes to enlarge when they are clicked on. I see how to add a second and third image to the product description which enlarge when they are clicked on but can’t figure out how to enlarge an attribute.

   In the attribute controller you can set one to a default (selected) and avoid the customer not selecting any/or one.

Don't know if this might help

I appreciate your reply Kobra, thank you.

What I'm looking for is in addition to the warnings at the top of the page is to have the required items that were missed to be highlighted in red.

If you set one to be the default - there will not be any missed ones and no "warnings" about missed ones

But you can control the look in the stylesheet with- and adjust to suit

.messageStackCaution {
	background-color: #FFFF66;
	color: #000000;
