How to center and spread the values of form tabs

is there a way to center and spread the vertical form tabs at the top of the form?

You can center the tabs with this code: 

ul#tabs-list {

    margin-left: auto;

    margin-right: auto;

}

You can handle the tabs with this code, note that the current code only changes the tabs height and width, but with the selector you can change the margins or anything else you want: 

li[id*="tab"]{

    width: 100px;

    height: 40px;

}
