Upload How Do I Upload A Css Layout To A Free Website Account?

How do I upload a css layout to a free website account? - upload

Throughout the morning, I understand, I tried to load such as a drawing. Someone has done for me, I believe, correctly used winrar to unpack, but I can not understand how to go online. I tried to upload using the ratio of the story, but ends with the original draft it.
If I am anything but blank pages?
A detailed help is certainly welcome!
Thank you.
