I suspect that the issue is because the calendar is larger than the container it is in. See if I inspect the element and remove the custom width, the calendar gets centered:
Can you please try the following and let me know if it fixes the issue:
Replace the width of the class “Kalender grid” with 100%
Publish the site
Reload the live site
If this fixes the issue and you’re happy with the way it looks, make sure you’ve made the update on the largest breakpoint where you’ve used that custom width.
If this fixes the issue but you need to use a larger width, replace the container with a div block.
Note: use VW (viewport width) for width not VH (viewport height).
If this doesn’t fix the issue, let me know and I’ll troubleshoot further.
I changed the container with a divblock. Afterwards I adjusted the width of the calendar to 100%.
Do I need to adjust the calendar on the different breakpoints? Also I only have this problem with the calendar of the U7. I don’t have problems with the other groups.
