I would suggest this for matching Chrome's style, extended from Jarish's example. Notice the cursor property which previous answers have omitted.
cursor: text;
border: 1px solid #ccc;
font: medium -moz-fixed;
font: -webkit-small-control;
height: 200px;
overflow: auto;
padding: 2px;
resize: both;
-moz-box-shadow: inset 0px 1px 2px #ccc;
-webkit-box-shadow: inset 0px 1px 2px #ccc;
box-shadow: inset 0px 1px 2px #ccc;
