Customizing contact form borders and fields

Site URL: http://www.sauseofsound.com/contact

I am having an issue in 7.1 where I am trying to achieve a simple underlined contact form, except when you click on each field to type, there is a bounding box that appears (see picture). I can't figure out how to get rid of this. Anyone else run into this or have solutions?

in case anyone else runs into this, this is how i solved it–

*:focus {
	outline: none !important;
}

Add this code to Design > Custom CSS

/* form block outline */
.form-block *:focus {
    outline-color: transparent !important;
}
