You need to add a line like this to define the background color of the whole page
A$ = A$ + |<style> body { background-color: yellow; }</style>| ' this defines the back color of the page (body)
Then you need to add a line like this to center and define the back color of the content
A$ = A$ + |<div align="center" style="background-color:brown;">| ' this permit to define the back color and the alignment (<div>)
