Small contact form

Hi,

My client wants a small contact form. I found this code on a different thread and added it to custom CSS, but it didn’t make a difference:

.ajax_form, .ajax_form fieldset{
margin-bottom: 0 !important;
}
.ajax_form p{
margin: 5px 0 !important;
}
.ajax_form label{
margin-bottom: 0 !important;
}
.ajax_form input {
padding: 8px !important;
}

Thanks for looking into this for me.
