Why does my animation doesn't work on my css?

Issue

I have a little problem and I need a second eye on it, here is it: I created an animation for bar progression but seems it's doesn't work and I can't figure why

.prog {
  height: 25px;
  border-radius: 25px;
}
.loading_container {
  width: 40%;
  margin: auto;
  border: 3px solid #9985FB;
  background-color: grey;
  box-shadow: 0 0 15px #9985FB;
}
.progess_bar {
  width: 0;
  background-color: red;
  animation: progress_bar 10s infinite;
}
@keyframes progress_bar {
  0% {
    width: 0;
  }
  100% {
    width: 100%;
  }
}

<div class="prog loading_container">
  <div class="prog progress_bar">
  </div>
</div>

I can't figure out where is the problem all attributes seems fine and every bracket is open and closed. Thanks for your time in advance.

Solution

In your stylesheet,

• .progess_bar

should be:

• .progress_bar

---

Working Example:

.prog {
  height: 25px;
  border-radius: 25px;
}
.loading_container {
  width: 40%;
  margin: auto;
  border: 3px solid #9985FB;
  background-color: grey;
  box-shadow: 0 0 15px #9985FB;
}
.progress_bar {
  width: 0;
  background-color: red;
  animation: progress_bar 10s infinite;
}
@keyframes progress_bar {
  0% {
    width: 0;
  }
  100% {
    width: 100%;
  }
}

<div class="prog loading_container">
  <div class="prog progress_bar">
  </div>
</div>
