As you can see, the left block with the image is quite big and can’t be reduced. Also, I’d like to align next to each other the elements in the right block. I’d like for the footer to be a proper line. What is the solution ?
Because you only mentioned the desktop interface, I only did it for the desktop interface, I think it is better to leave a space on the two sides to make the footer more beautiful.
If you want, I can further edit the header for you. Note: if you want to add more links later, increase the value from 55% to 60%, 65%,.. depending on your wishes.
