Changing the background color or image of a Miiduu store can be achieved using the theme settings.

Go to your store administration-> Design-> Theme->Theme Settings-> Global-> Body background color. Click the color and a 
palette will pop up, just select the color you want to use and click 'Done'. Remember to click 'Save' after changing it.


To change the background you can go to Theme Settings->Global->Body background
Click on the image on the right of”Body background”. Then you will see a pop-up for you to upload images. If you want to change the background of other pages, such as Header and Category&Search page, you can follow the steps above.

Please note: To change the background image, it's better to download the original picture and change the color based on it. Remember to keep the size and aspect ratio.
