A way to do this would be to set the color of the element to black  and then fade to the color of the background like this    lt style gt   p   animation-name  example  animation-duration  2s      keyframes example   from  color black   to  color white      lt  style gt   lt p gt I am FADING  lt  p gt    I hope this is what you needed

If you need a single fadeIn Out without an explicit user action  like a mouseover mouseout  you may use a CSS3 animation  http   codepen io anon pen bdEpwW   elementToFadeInAndOut        animation  fadeinout 4s linear 1 forwards        keyframes fadeinout     0    opacity  0      50    opacity  1      100    opacity  0        By setting animation-fill-mode  forwards the animation will retain its last keyframe  By setting animation-iteration-count  1 the animation will run just once  change this value if you need to repeat the effect more than once
