Border around input text fields

[Forrest]

Hello

I would like to have a border around the input field.
Around a select field there's a border
But nog around the other text fields

In the CSS is original

.ckCSSinput {
width: 76%;
margin-top: 10px;
background:none;
border: 1px solid #999
}

So I presume it would give a border...

example
http://bax.be/joomla/index.php?option=com_ckforms&view=ckforms&id=1&Itemid=213

Where can I/do I have to chenge the css code?

I added a border around the form itself in the css, no problem
But vcannot find where to add a border around the text fields

Any help would be nice!
