O.k. thank you for the update.
So, if you have custom fonts installed then it possibly overwrites the CSS? Thanks for coupling that back, did not know that.
Ah, so you wanted to get rid of the line breaks, I understand now.
This should get it on one line:
<br />
#page .site-title > a {<br />
font-size: 31px;<br />
white-space: nowrap;<br />
}
It works from over here, but let me know if you have a different experience.
Site titles are 'usually' a certain length, yours being quite long accounts for some of the difficulty. Looks nice how you solved it.
Should you still want to change it, the code is up there. If your getting stuck feel free to couple back.
If your fine with the way you solved, don't worry about it, and you don't have to reply.
Take care!
