title: Using Flex/CSS with wkhtmltopdf
body: <p>I've successfully created a list using the following answer with flexbox on my HTML page <a href="https://stackoverflow.com/questions/48464444/how-to-display-3-items-per-row-in-flexbox">How to display 3 items per row in flexbox?</a></p>
  
  <p>I have a need to create a PDF with this data and I'm using wkhtmltopdf (<a href="https://wkhtmltopdf.org/" rel="noreferrer">https://wkhtmltopdf.org/</a>) which also works fine however the PDF generated has all my List Items in 1 long column instead of 3 per row.</p>
  
  <p>Looks like the CSS is not being processed when the PDF generation is happening any insight is appreciated.</p>
