I have been playing around with blogger themes and the customizer and noticed that different themes show different customization options. I also see some themes use completely undocumented features.
My question is, where can I find documentation on the blogger template language and ideally how these affect the "customizer"?
As an example of topics that I cannot find documentation for (again, my question is if there is any in-depth documentation about blogger templating language, and not with the questions below specifically):
<macro:include>… cannot find any documentations about it or what it does
- The "Awesome" theme allow me to select the "layout" in the customizer, but no idea how that is described in the template itself. E.g., can choose sidebar location, number of sidebars, or number of columns in the footer
- How to define the theme colors that show in the advanced selection? Some themes have tens show, others a handful.
- Some themes allow to "adjust widths", but others do not.
- Documentation about what the supported page elements like sections or widgets are?
