How do I animate the steam from a cup of coffee in my SVG icon code?

I am a graphic designer just learning about SVG animated icons and coding. I illustrated a cup of coffee in illustrator and then exported it as an SVG file. I try to revive the steam so that it rises like real steam. The problem is it doesn't animate the steam even though I have .steam1.st1 selected in CSS. I might just be confused by the amount of tutorials I have looked at. Can anyone take a look at my HTML for illustration and help me animate it correctly using CSS based on this code http://codepen.io/anon/pen/DLmCn

Here is my SVG code in HTML http://codepen.io/anon/pen/niHCA

This is where the starting point of your code starts quickly: http://codepen.io/anon/pen/rAdom?editors=101

First, define the keyframes for your animation:

@keyframes steaming {
    0% {
      transform: translateY(0px);
      opacity: 0;
    }

    50% { opacity: 1; }

    100% {
      transform: translateY(-10px);
      opacity: 0;
    }
}

@-webkit-keyframes {
 ...
}

      

The steam will start invisible (opacity: 0), then fade out (opacity: 1) and retreat as it moves up, as defined by translateY (-10px). Note that the pixel values ​​are scaled according to the SVG representation and the height / width values.



Then, apply these keyframes to each of the SVG elements in the pair using the classes you've set:

.steam1{
  -webkit-animation: steaming 7s linear infinite;
  -moz-animation: steaming 7s linear infinite;
  animation: steaming 7s linear infinite;
}

      

You can adjust the speed of the animation to make it look a little better.
