Removed margin from body element

[darkeclipz]

I have removed the margin from the body element with an extra style tag.

It might be worth noting that the default width (if the container size is not set to max) is 704 pixels. I also changed the default width to this.

This allows the component to render nicely in the container in which it is created. :)
