So I've set my input, textarea and select elemtnts width of 97%. Everything is showing fine, but select element is always a bit shorter then rest. See picture for screenshot.

How to fix this? :)

Okey I fixed it byt adding extra margin to select element, here is css.

#cat_add_form input[type="text"], #edtCatDescr, select, .fileUpload
{
    background-color: #ffffff;
    width: 97%;
    padding: 4px;
    margin-bottom: 6px;
    font-size: 16px;
    border: 1px solid #dfdfdf;
    display: block;


    /* CSS 3 */
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
}

#cat_add_form select
{
    margin-left: 10px;
}
