I would like to apply an effect when scrolling the text of a div, similar to the effect below (which I stole from a website):

PS: Run as fullscreen;

body {
  background: #f8fafc;
  font-size: 20px;
  font-family: "Crimson Text", serif;
  color: 444;
}

h1 {
  padding-top: 100px;
  font-weight: 600;
}

h1, h3, h4, p {
  width: 600px;
  margin: 20px auto;
  display: block;
}

h4 {
  color: #666;
}

div.blur {
  position: fixed;
  width: 100%;
  height: auto;
  left: 0;

How could I create this effect without creating all this gambit in a way that works on all current browsers?

html5 css3

  • Utilize background gradient or an image png (for older browsers) with the effect.

  • how would I do that?

Dude I got a similar result, see if it’s something like this!

body {
  background: #f8fafc;
  font-size: 20px;
  font-family: "Crimson Text", serif;
  color: 444;
}

h1 {
  padding-top: 100px;
  font-weight: 600;
}

h1, h3, h4, p {
  width: 600px;
  margin: 20px auto;
  display: block;
}

h4 {
  color: #666;
}

#fade {
  background: linear-gradient(rgba(255,255,255, 0.9), rgba(255,255,255, 0), rgba(255,255,255, 0.9));
  position: fixed;
  height: 100vh;
  width: 100vw;
  left: 0;
  top: 0;
}

    As I commented in @hugocsl’s reply this effect will not work if the background has a background image.

  • Where would you add this background image ?

  • at the bottom of the page

  • I’m sorry but I didn’t understand what your intention, it would be that the background of the page did not fade ?

  • Change the second line of your CSS background: #f8fafc; for background: blue; and see the result
