title: Make white background of image transparent in css
body: <p>I have two images, one of which is a small icon that is superimposed over the first image. My icon has a white background, so when the icon is placed over the other image, we get this effect where a white square appears over the image.  Ideally, I do not want to display this white background on top of my other image. Is there is a CSS property I can apply to my icon to make its white background transparent? </p>
