@힙찔이닷컴 You should elaborate a bit more here and provide at least an error message - or better still, a detailed overview of what isn't working, or what results you got instead of what you expected.
It's impossible for us to help you without this.
I believe the loading bar should have a display: none; when finished loading instead of a width of 0%. It still shows after loading of the site is done. I'm not sure if this was intended or not, but in a UX standpoint, it should be hidden. When you think about it, it still looks like its hanging at 100%.
