Font size and space between text in menu

Hi Sakin, I'm trying to put my menu on one line on : http://nova-tek.fr/depannage-informatique/ I would like to know if it's possible to reduce the space between the text in the menu. I already tried to reduce the font size but my menu is always on two lines instead of one. I tried this in custom CSS : #header-menu ul.menu a { color: #ff6600; } #header-menu ul.menu ul a { color: #ff6600; } #branding ul.menu a { color: #ff6600; font-family: Arial, Helvetica, sans-serif; font-size: 10px; } I would also like to know if it is possible to align the menu to the left because at the moment it is centered Thanks for your help
