All fonts sizes (titles, body news, etc), because when i increase the font one mobile it increase in pc view too. I want it indepenent and i want to know how i do it.
you can set the mobile font size for the body with this CSS:
@media(max-width: 768px) {
body {
font-size: 18px;
}
}
In the Customizer > Typography > Headings settings you have a separate Mobile option for each of the H1-H5 font sizes, simply click the mobile icon beside the field.
