Solved My menu does't show in footer on mobile

Hi,
I'm building a shop site for my friend. I used Divi and Woocommerce but there seems to be a problem with the menu in footer on mobile - one can see only titles, no menus are visible. I've used a code I found here in help, which is
"

#main-footer {
position: relative!important;
}
#page-container #main-footer .container #footer-widgets .footer-widget {
display: block!important;
}
"
but it didn't work.
I have no idea what may be a reason.
In advance thanks for your suggestions.

Never mind - I found the reason. I don't know where but somewhere the display option on mobiles was set to "none" so I used CCS to correct this one and it helped.
