You can apply css to dynamically created textbox like this...

var el = document.createElement('input');
el.className="txtStyle";

then add that css to your page like this..

<style type="text/css">
.txtStyle
{
    color:Red;    
}
</style>

Hi dotsandcoms,

what not work?

put a css style, if not, what style must be applicated?

for example, put the next code

<style>
input {
    background-color: red;
}
</style>
</head>

you can see your inputs with background red.
