A couple things:

1. You need to use # for id selectors (the period is for class selectors)
2. To override inline style you'll need to add !important

#form-title-wrap {
    padding: 0px 0px 0px 30px !important;
}

However, it depends what you're trying to do. If you have a logo image, the value of the form wrap padding is generated based on the logo size/margin in which case changing the title wrap padding alone might not actually make any noticeable difference.
