Hi Rebecca,
1. For Color size, you can the color code in the following CSS as per your need and in the “Appearance => Customize => Additional CSS” box:
.header-media .section-title,
body:not(.home) .header-media .section-title {
color: #000;
}
For Font Size, you need to adjust it for Mobile and then Desktop, so adjust the following CSS font size as per your need and then add it in the “Appearance => Customize => Additional CSS” box:
/* Header Media Font Size for Mobile *
.header-media .section-title,
body:not(.home) .header-media .section-title {
font-size: 32px;
}
/* Header Media Font Size for Desktop *
@media screen and (min-width: 64em) {
.header-media .section-title,
body:not(.home) .header-media .section-title {
font-size: 60px;
}
}
Regards,
Sakin
