In the elegant code devised by esdd found here, how do you go about removing the headers and footers in the "blank" pages between chapters?
Here is his code:
\documentclass{book}

\newlength\outermarginwidth
\setlength\outermarginwidth{2cm}

\setlength\chapternumbersize{60pt}
\colorlet{outermarginbgcolor}{lightgray}
