Images not aligning & moving content to the right

My background image doesn’t line up with my top graphic and I want my top graphic aligned all the way to the top left but I can’t get it. I changed all the margins & paddings to 0 but it still has some space between it. How do I fix this?

Been changing my header and my stylesheet. I am using the default theme.

Also my content is to the left (I moved it there but I forgot how I did that) now I would like to move it back. How do I do this?
