Dynamic color and dynamic font options are crucial. Unless I am missing something about ACF. Flexible content is the most client-friendly way to integrate oxygen. Though at it’s current state it still requires you to create a code block for the flexible content PHP. As well as having to utilize Oxgen template shortcodes for the flexible blocks. The inability to control colors and complete font styles is a hindrance.
It seems at least to me, that Oxygen is designed around the idea of page sections. There is no more client-friendly way of doing it than the use of page-specific flexible content areas.
Has anyone developed a sound way of doing this?
