Hi,

1.  2. 3. pls. provide the wp-admin access.

Hi,

1. To make this you need to edit template:

/wp-content/themes/thegem/footer.php

before the editing copy this file to the child theme for the safety updates.

Or you can use custom footer, take a look:

3. pls. use following css:

@media (max-width: 500px) {
.vc_sep_holder {
    display: inline-block;
}
}

here is an example of CSS for controlling font size for mobile:

@media (max-width: 1000px) {
h1, .title-h1 {        
    line-height: 30px !important;        
    font-size: 30px !important;
}
h2, .title-h2 {        
    line-height: 30px !important;        
    font-size: 30px !important;
    }
}
@media (max-width: 768px) {
h1, .title-h1 {        
    line-height: 30px !important;        
    font-size: 30px !important;
}
h2, .title-h2 {        
    line-height: 30px !important;        
    font-size: 30px !important;
    }
}
@media (max-width: 500px) {
h1, .title-h1 {        
    line-height: 30px !important;        
    font-size: 30px !important;
}
h2, .title-h2 {        
    line-height: 30px !important;        
    font-size: 30px !important;
    }
}
