Catogories on mobile disapear and mobile display wrong

[Beyond2000]

Hi
On the mobile device the catogories banner disapear. The items is also showing everything underneath each other and not 4 in a row like on the desktop.
And please do not tel me to use the menu button on the mobile. Clients won't know that that is why it is supposed to be like on your adverts on the Abantecart. the display is supposed to look exactely the same on ALL the devices.

Please help me fix this

You need to modify your template or install some another categories menu block "without menu button"
