User Guide has 1000 pixel wide pages, can't reflow text

Many pages in User Guide have very long lines of text (1000 pixels) which do not adjust to the width of the browser window. This forces the reader to open the browser to the full screen width on a common 1366 pixel wide laptop. This is inconvenient for readers that want to view more than one document at the same time and goes against principles of responsive web design.
