title: CSS or image for background and menu arrows?
body: <p>Is is better to use CSS or image for these two cases:<br>
  1) Need a gradient like shading of purple on my homepage (color fades from dark purple to light purple)<br>
  2) All the menus on my site have an arrow "More " and when opened it changes to "Less "   </p>
  
  <p>Currently my design team has made the homepage as CSS and the arrows as images. But I cant see any advantage or disadvantage of one over the other or what is best practice to use?</p>
