@zmand13 Hi
1) You can add this in custom.css file and adjust padding 20px value accordingly
.t3-masthead .ja-masthead .ja-masthead-detail{padding: 20px 22px !important;}
2) Try add this again in custom.css file and change color code, font-size accordingly :
.t3-masthead .ja-masthead .ja-masthead-detail .ja-masthead-title{color: #ffffff !Important;font-size: 60px !important;}
.t3-masthead .ja-masthead .ja-masthead-detail .ja-masthead-description{color: #ffffff !Important;font-size: 20px !important;}
You can let me know if these have worked so as to pursue further with third query 🙂
