The missing option to outline layered icons when using Font Awesome SVG+JS.
This small CSS file works with the SVG+JS version of Font Awesome, and was tested with version 5. It may work with version 6, though has not been tested.
<head>
<link rel="stylesheet" href="path/to/fa-glow/fa-glow.min.css" />
</head>
<body>
<span class="fa-layers fa-fw fa-3x" aria-hidden="true">
<i class="fas fa-database" style="color:grey"></i>
<i class="fas fa-plus" data-fa-glow="9" data-fa-transform="shrink-8 down-5 right-4" style="color:green"></i>
</span>
<script src="path/to/font-awesome/js/all.min.js"></script>
</body>Attributes are added to the icon elements.
data-fa-glow
- Adds an outline to the icon using the default width (8).
data-fa-glow="5"
- Adds an outline to the icon with 10 times the width set.
- Whole numbers between 1 and 10 are accepted.
style="--fa-glow-color:red"
- Sets the color of the outline.
- When unset, the default color (white) will be used.
fa5-power-transforms-css
offers a lot of Font Awesome's Power Transform functionality,
including limited support for the data-fa-glow attribute.
