Hello Art,

1. to modify the font attributes on mobile for the fullscreen slider:

@media only screen and (max-width: 767px){
    .title, #showcase-carousel-slider .outer .title {
         font-size: 50px;
         line-height: 80px;
         height: 80px;
    }

}

in customizer -> additional CSS

2. look in /js/scripts.js for the following lines

time = ((EstimatedTime/1000)%50) * 50

line 44

and

durataion = time + 400;

line 56

lower the values for these assignments

hard refresh the page (Ctrl+F5) to see the changes

Hi Art for project pages you have

@media only screen and (max-width: 767px){

    .hero-title, .page-title {
        font-size: 50px;
        line-height: 80px;
    }

}

and change the font attributes as you wish
