HTML CSS: Use Collapsible Toggle with SVG Icon

Question

I want to replace a FontAwesome Icon with Google Materials SVG Icon, after a collapsible table button toggle is pressed (goes from down arrow to up arrow). Current Code is this. I cannot get Google Material Icons code working. How would i fix this?

Should work like this, except with Google icons:

.card-header .accordion-toggle:after {
    font-family: 'Glyphicons Halflings';
    content: "\e114"; 
    float: right; 
    color: grey; 
}


.card-header .accordion-toggle.collapsed:after {
    content: "\e113";
}

Google Material Icons:

.card-header .accordion-toggle:after .material-icons{
    content: "\e5cf"; 
    float: right; 
    color: grey; 
}


etc

First you need to include the Google web font

<link href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet">

Inside the css definition for the toggle buttons you need to replace

font-family: 'Glyphicons Halflings';

by

font-family: 'Material Icons';

and lastly

content: "\e114";

by either

content: "expand_less";

or

content: "expand_more";

Here's an example based on your code:

.panel-heading .accordion-toggle:after {
  font-family: 'Material Icons';
  content: "expand_less";
  float: right;
  color: grey;
}

.panel-heading .accordion-toggle.collapsed:after {
  font-family: 'Material Icons';
  content: "expand_more";
}
