Horizontal flags with Virtue theme

Hey!
I have added the qtranslate menu widget to the top bar of my page. The menu itself works fine, however I would like the flags to be aligned horizontal. I have found a few solutions to this problem on google but the entries very several years old and did not work for me.

I’ve tried following the explanation given in the widget CSS code but at no prevail.
The code that I tried to change:

.qtranxs_widget ul li
{
display: inline; /* horizontal list, use "list-item" or other appropriate value for vertical list */
list-style-type: none; /* use "initial" or other to enable bullets */
margin: 0 5px 0 0; /* adjust spacing between items */
opacity: 0.5;
-o-transition: 1s ease opacity;
-moz-transition: 1s ease opacity;
-webkit-transition: 1s ease opacity;
transition: 1s ease opacity;
}

I’m not a website or coding genius so maybe the solution is easy and I’ve just missed it. If that’s the case I do apologise ??
