I am trying to put a FontAwesome icon by css but whatever I do it keeps showing a blank rectangular thing.
I have checked all.css and the file is well connected. I have no idea what I did wrong. Please give me advice on this.
<head>
<meta charset="utf-8">
<title></title>
<link rel="stylesheet" href="css/all.css"> <!--well connected-->
<style>
h1 {
font-size: 20px;
}
h1::before {
content: "\f053";
font-family: FontAwesome;
font-style: normal;
font-weight: normal;
}
</style>
</head>
<body>
<h1>arrow</h1>
</body>
