Global HTML code
This is where you can add HTML code to be displayed on every page on your website.
Writing and using HTML code requires special skills and can lead to unpredictable results and website rendering problems. If this happens, you can temporarily disable this code while you make the necessary adjustments. To do so add ?disable-global-html to the address of the current page.
Example
You can also add code in the <head> tag or the <body> tag. This is what it should look like:
<!DOCTYPE html>
<html>
<html>
<head>
<meta name="country" content="USA" />
</head>
<meta name="country" content="USA" />
</head>
<body>
<div>Welcome to my website</div>
<script>
var year = 2020;
</script>
</body>
<div>Welcome to my website</div>
<script>
var year = 2020;
</script>
</body>
</html>
