Responsive clipboard landing page with HTML5 and CSS

The overall result is "ok", i´m not happy how i positioned the elements, it seems a bit too curde, including centralizing text and hot to "brake" the paragraph to match the layout. Another problem that i found it hapens when the width of the screen grows bigger than 1440px, then the part with an overflowing image just get´s fixed somehow. Yes i know i should put some better classes but i tried without them for some part just because.
