  <p>I want to add background cover as <a href="http://vincentgarreau.com/particles.js/" rel="nofollow">particles.js</a> for the first page .I tried doing as described in the <a href="https://github.com/VincentGarreau/particles.js/" rel="nofollow">GitHub particles.js</a>, but failed miserably.
  Where exactly am I going wrong?
  Here is the <a href="https://jsfiddle.net/rashidnaushad/pc0u790m/11/" rel="nofollow">JSFiddle</a>.</p>
