i guess there are some issues with the x-corporate theme and the firefox browser. who else has some disyplayproblems with browsers?
It would be very helpful if you could explain your displayproblems in detail.
in chromium it looks like in the demo, but only in cromium. vivaldi has the same issues like firefox
looks like the surrounding list element is not clearing the previous one. Either each element should be
display: block; or if each item is floated, then they need to be ‘cleared’ https://www.w3schools.com/css/css_float.asp
You should report this on the theme repo issues: https://github.com/tranduyhung/grav-theme-x-corporation/issues
