Setting the width of both the textbox (ie. input type=\"text\") and the textarea to 500px doesn\'t work in IE6 and Chrome, only works fine in FF2 (haven\'t tested other browsers
I use CSS3 to make textbox and input work the same. See jsFiddle.
.textarea, .textbox { width: 200px; -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; }
Works in IE8+, see caniuse.
