title: Scale HTML proportionally to fit exactly to PDF A4 size
body: <p>I am using PHP, Mysql, jQuery. I have a webpage that is to be converted into high-res A4 size PDF: <a href="http://optisolbusiness.com/funeral_site/sample/index/id/255" rel="noreferrer">http://optisolbusiness.com/funeral_site/sample/index/id/255</a>.</p>
  
  <p>I have converted the HTML to PDF using <code>wkhtmltopdf</code>, which works great.</p>
  
  <p>Here is the generated PDF <a href="http://optisolbusiness.com/Guru/Gurupdf/optisol.pdf" rel="noreferrer">http://optisolbusiness.com/Guru/Gurupdf/optisol.pdf</a>. But the HTML is not fitting exactly to PDF size; There are spaces around the HTML in PDF. How to scale HTML to fit A4 PDF size 100%? Importantly the content inside the html (ie) text size, images width and height, background images also to be scaled proportionally.</p>
