!!!!! Logo Resize Problem~

Hi~
1: I’m trying to resize the logo. I tried the code:

“/*header with social icons: */
.social_header #header_main .container, .social_header .main_menu ul:first-child > li a { height: 116px; line-height: 116px; }”.

After I changed the height to 200px, the Homepage didn’t change anything. Only some of pages were changed. So what happened?? Or is there something else I can do to fix it, maybe some different codes??Here is my website link: http://wholeren.com/
2: I also want to change the shrinking scale of my logo. So I find this code:”if(st < el_height/1.5)
{
newH = el_height – st;
header.removeClass(‘header-scrolled’);
}
else
{
newH = el_height/1.5;
header.addClass(‘header-scrolled’);
}”
But I didn’t find the file:” avia.js” in the Editor. Where could I find it???

Thanks~
