Top Menu buttons don't fit on 1 line

See miralomasf.com

The last top menu button "Tours" does not always appear in the right spot (on the top line).

On some laptops, it appears below "Home", overlapping with the "Newsletter" mondule.

There seems to be enough space on the right to "Auction", so I don't understand why that happens.

How can I fix this?

There's not enough space, as module with social networks buttons occupies a part of that space. You can decrease font size of top menu by editing template_css.css file, under #nav a (around line 260). It's currently set to 16px.

I'd rather leave it to 16px, but use the space that is now occupied by the social network module. Would that be possible?

I hope it's not too late to answer.

Edit layout.css There you can experiment with width parameter.
Maybe you should also change the float property from 'left' to 'right'.

Thanks Pirossi. Very helpful and not too late!
