Cody –
Made some changes in custom CSS – pls check the contents. If you need, pls make the change to the logo image sizes. I haven’t checked the same in IE – hope it works.
I made some changes to sticky menu as well to make the transition look more natural. Hope you find that good enough for now.
The page section are not supposed to be exposed to public and is to be used only as part of single page site template. If you have a need for the same, pls create a page instead of a page section and you will have the option to display the login widget there.
I could not reproduce the spinning wheel on my machine here. All pages seems to be load almost immediately.
