If I take css script from this example W3Schools and I put it into 2 external css file (font.css and menu.css) and then I called them in html, the arrow from Dropdown menu disappear.
The content from https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css is in font.css and the entire content of tag <style> is in menu.css.
I can't include web link because I don't have access to internet where I want to create this.
The code ended like this:
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="font.css" >
<link rel="stylesheet" type="text/css" href="menu.css" >
</head>
<body>
<!–– Rest of the code...-->
</body>
</html>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">I mean this<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">is included in the<head>). Make sure to add it if you want it to work ;)font.csswith the script fromhttps://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.cssI forgot to mention that I don't have access to internet.
