Django: overriding admin css in django

Method 1: Override admin template

In django admin templates, there’s

{% block extrastyle %}{% endblock %}

and can add some styles to there.

Method 2: Add Media class to ModelAdmin

If you want to add css or js for only one ModelAdmin, you can add Media class to ModelAdmin

class CustomModelAdmin(admin.ModelAdmin):
    class Media:
        js = ('js/admin/my_own_admin.js',)    
        css = {
             'all': ('css/admin/my_own_admin.css',)
        }
