Hello,
We do not service other people’s custom code and we cannot fix your custom. First, you need:
1. Adjust the header normally for mobile, placing the elements from the left in the left column, the logo in the central column, the elements from the right in the right column.
2. Adjusts the width of the logo so that there is enough space for other elements on mobile devices.
3. Remove the entire custom CSS code for the header.
4. If the width of your custom language switcher bothers you, leave the part of the custom CSS responsible for its width.
Kind Regards
