It's not a frame. It's a normal block element.You can make an element that blocks the entire page with HTML and CSS, but you'll need Javascript to make it appear and disappear.

.block {position: fixed;top: 0;left: 0;width:  100%;height: 100%;background-image: url(transparent.png);z-index}

To make some elements accessible, like a smaller box with a message, put them inside the element with the ".block" class.If you're having trouble understanding the code, or what I'm talking about, please look through the HTML and CSS tutorial.
