I have this html text on many pages
<head>
<meta charset="utf-8" name="viewport" content="width=device-width, height=device-height minimum-scale=1, maximum-scale=1">
<title>Account</title>
<link href="css/Master.css" rel="stylesheet"/>
<link rel='stylesheet' media='screen and (max-width: 450px)' href='css/narrow.css' />
<link rel='stylesheet' media='screen and (min-width: 451px) and (max-width: 800)' href='css/medium.css' />
<link rel='stylesheet' media='screen and (min-width: 801px)' href='css/wide.css' />
</head>
The problem is that I want to use this same code for many pages without having to copy and paste over let's say 5 pages. Is there a clever way to use an "include" command for this?
