The problem with the h1 tag?

Hello, I'm new to html/css and recently started to impose themselves for the layout, so to say it is time and practice to do, and not infocredit.
Ah Yes, the crux of the matter, I don't understand why I have the text in the tag "p" button, input[type="button"] pressed against the left edge, but with h1 some sort of trouble, do not want intends to prescribe margin-right, I think maybe some have a hidden Saint, which according to the standards makes the indentation to the left, but the way margin and padding reset.
When the selection shows the left indent of a couple of pixels.
Here are screenshots and code:
p.s I can criticize for the wrong code, I'd like to listen adequate criticism.

Solution
Compile the answer.

This is the internal size of the letters. Written in the font when creating it, that's fine.

If it is critical, then a negative margin with em you will save:
