How to add a ring around bootstrap glyphicons

Question

How do you add a ring around bootstrap glyphs, without using a solid circle? I have seen an example where you just sit a glyph over the top of the circle glyph, but then you don't get the correct background colour, as shown below.

Answer 1

Here's an example of how to display and position an icon inside another (circle) div with modular background/color/border options.

See working Snippet.

/**CSS FOR THE RING**/

.glyphicon-ring {
  width: 60px;
  height: 60px;
  border-radius: 50%;
  border: 4px solid white;
  color: white;
  display: inline-table;
  text-align: center;
}
/**CSS FOR ICON WITH NO BACKGROUND COLOR**/

.glyphicon-ring .glyphicon-bordered {
  font-size: 20px;
  vertical-align: middle;
  display: table-cell;
}
/**WITH AN ADDED BACKGROUND COLOR**/

.glyphicon-white {
  background: white;
  color: black;
  border: 4px solid black;
}
.glyphicon-teal {
  background: teal;
  color: orange;
}
.glyphicon-red {
  background: red;
}
