Question

The django documentation indicates that custom css can be added to an Admin page as follows:

class ArticleAdmin(admin.ModelAdmin):
    class Media:
        css = {
            "all": ("my_styles.css",)
        }
        js = ("my_code.js",)

It doesn’t, however, explain what the “all” means in the css declaration. What does it mean, and are there other values or configurations one could potentially use instead of “all”?

Answer 1

all is for all types of media declarations which are:

‘aural’, ‘braille’, ’embossed’, ‘handheld’, ‘print’, ‘projection’,
‘screen’, ‘tty’ and ‘tv’

.

so, if you want a specific style for handheld:

class ArticleAdmin(admin.ModelAdmin):
    class Media:
        css = {
            "handheld": ("my_handheld_styles.css",)
            "all": ("my_styles.css",)
        }
        js = ("my_code.js",)
