Tagline & Testimonials Slider

Hi, What is the CSS to display the tagline but hide the site title? and to place it underneath the logo? Is it possible to slow down the slider for the testimonials? Can the button in Header Right work as a phone number for click to call? On the home page I have the title for the Testimonial slider to be enabled, but it fails to display. What could be preventing it from showing? Where are the settings for the features on the demo contact section? Thank you
