I have lots of text in a small box which you can resize thanks to the CSS3 resize property.

Code used in this page

.resize {
	width: 100px;
	height: 50px;
	border: 1px solid #000;
	overflow: auto;
	
	/* Firefox */
	-moz-resize: both;
	/* WebKit */
	-webkit-resize: both;
	/* Google Chrome */
	resize: both;
}
