Multisite/multilanguage problem

Hi,

I’m using enfold theme with WPML basic version in two languages.
I’ve wanted to resize font in main menu so I pasted this in Quick css box in main language version:

<code<.main_menu ul:first-child > li > a { font-size: 15px; }

Now when I’m log in and I update content in second version, everything seems be correct. But after log out new changes on the second language version are not visible

Can you help me resolve that problem, please.

Artur
