pre-loader

As my lecturer gives me link about creating pre-loader with some codes in it. I tried it out. However, my page turned to be white and can not see my parallax scrolling visual.

Then, i found more simple tutorial about pre-loader without any codes. And my parallax still working well. But, i do not see any "loading" page before going to my parallax scrolling page. I assumed that my file size is not too big to use pre-loader page. I will try to see it in online ASAP.

Below is the tutorial of creating pre-loader.

And this is how my "loading" page is supposed to be looked like.
