Change form line font

I'd like to change the font style of the line fields of my form.

i've been able to bold the first line 'title' (with the below code) but would like to change the other 4 lines below it.

 .form-wrapper .field-list .section:first-child .title {
    font-size: 1.2em;
    text-transform: none;
    padding-top: 0px;
    font-weight: bold;
}
