From another thread, I learned I could add another website variant, so I added the tablet. I can't tell where to adjust the lines to for the new variants, that being the "mobile" and the tablet. The tablet looks like it is small (narrow), like the phone but the variant says between 400 and 720 px when I view the details. I assume I need to change this. And the Phone says up to 400 px but it's as wide now as the main variant, which was fine before I added the tablet.

Can anyone help me to fix this so I can add the tablet variant and make them the correct width? I'm not sure how to do it now that I created it.

Help.....
