How to change footer menu items from vertical to horizontal

you need to create some corresponding CSS;

review the general chapter from the Codex https://codex.www.ads-software.com/Creating_Horizontal_Menus

The thing above is out of my head,please need help

for the four lines of menu within the grey footer:

#menu-footer-menu { margin-top: 10px; }
#menu-footer-menu li { display: inline; margin: 0 10px; }

Thanks a lot for your support ,i added your mentioned code and it got 3 items in line but the fourth item is still below ,i want the fourth item(Terms and Conditions) in the same line ,thanks once again for your precious effort

I get all four in one line, using Firefox and Chrome browsers.

what browser are yo uusing, and how wide is the screen?

can you show a screenshot of the problem?

I have 3 in line ,last one below them ,you can see my screenshots here from chrome

could be a problem with different layout when being logged-in …

I see the content stretched fully over the screen, and a sidebar below it towards the bottom, and at the bottom the menu in one line.
