I would like to customise the theme by adding background images. The 'styleable_elements' image on the Moodle Mobile Themes says you can change three background images. But I don't know how to format the images for mobile apps.
What dimension, format, size, quality should I use (for each background image)?
Also the 'styleable_elements' image says what can be modified but not the css selectors to change that specific element. I'm sure it's simple but can someone tell me the structure of the app and what each section is called, or point me to a doc specifying the sections and their selectors.
