Menu Icon Animated

This is another example taken from the W3C Schools website on what can be done with CSS,

Click on the Menu Icon to transform it to "X":

Example Explained

HTML & CSS: We use the same styles as before, only this time, we wrap a container element around each <div> element and we specify a class name for each.

The container element is used to show a pointer symbol when the user moves the mouse over the divs (bars). When it is clicked on, it will execute a JavaScript function that adds a new class name to it, which will change the styles of each horizontal bar: the first and the last bar is transformed and rotated to the letter "x". The bar in the middle fades out and becomes invisible.

I had to rename the function as it interfered with the function in the FBM

The code for an animated hamburger

the css:

<style>
.container {
  display: inline-block;
  cursor: pointer;
}

.bar1, .bar2, .bar3 {
  width: 35px;
  height: 5px;
  background-color: #333;
  margin: 6px 0;
  transition: 0.4s;
}

.change .bar1 {
  -webkit-transform: rotate(-45deg) translate(-9px, 6px);
  transform: rotate(-45deg) translate(-9px, 6px);
}

.change .bar2 {opacity: 0;}

.change .bar3 {
  -webkit-transform: rotate(45deg) translate(-8px, -8px);
  transform: rotate(45deg) translate(-8px, -8px);
}
</style>

and the html:

<div class="container" onclick="myFunction1(this)">
  <div class="bar1"></div>
  <div class="bar2"></div>
  <div class="bar3"></div>
</div>

To get an animated icon on the page that discusses the Fixed Bottom Menu I added a new function that combined the two functions that both expanded the bottom menu and change the icon.
