I have been trying to figure it out by inspecting with Chrome but I don't see what is causing this.

1) what is it?
2) how can I figure it out, with Chrome inspect?

Thanks so much guys!!

 

That's easy... thru Firefox
Turn on Inspector and while your mouse is still within hovering range, right-click and press Q. I thought Chrome has same steps too, no?

.newsblog_menuitem:hover {
    letter-spacing: 12px;
}

Code (CSS):

 

I don't see it I don't see the "hover" at all.


I do see both the same things in FF and Chrome so that's good.

 

Here,
I hope this helps.

 

I found out the problem, by accident! I had to right click the mouse in the inspect window and select "hover" because it wasn't showing it by default! omg what a pain! thanks for the help much appreciated!
