Widget-Home Page Top Area

Hello,
At the moment, I have 4 big Arcade Icons in the Home Page Top Area.
But I’d like to add a 5th one in the same line.
If I add it at the moment, it creates a second line of Icons but I’d like to have the 5 of them aligned in the same line.
A solution would be to decrease the spaces between icons to fit a fifth one, can it be done?
Please help.
