If you want to change the css style for all input in your site or forms you must put it:

1. In your css file:

input {

color:#000;

font-weight: bold;

font-size:14px;

height:20px;

padding: 2px 2px 2px 5px;

font-family:tahoma,verdana,sans-serif;

border: 1px solid #696;

}

input:hover { background: #FFF; }

In input class I have put black color for the font and bold with a border and 20px in height

In input:hover I put blackground in white for resalt the font if you put the mouse over the input text

The code hover put background in buttons too

If you wants put the background only in the input type="text" then:

Replace:

input:hover { background: #FFF; }

by:

input[type=text]:hover{
background: #FFF;
}
