If you set up block paddings, font sizes, or shape dividers separately for the mobile site version, you can now restore these settings according to the desktop version of the website. When you change one of these settings individually for display on smartphones, this setting will have to be edited manually for mobile and desktop versions of the website separately. However, with the help of the “Auto adjust” button, you can restore the automatic adaptation of these settings for smartphones, which will be based on the desktop site version.
It may be needed when you manually configure some settings for smartphones and decide that it would be more convenient for you to edit these settings only for the desktop site version and automatically apply them to the mobile site version.
