Here are the steps on how to show a warning for non-JavaScript browsers:
1. Create a `noscript` element and add it to the HTML document.
2. Inside the `noscript` element, add the text that you want to display to users who are using browsers that do not support JavaScript.
3. To check if JavaScript is enabled, you can use the `if` statement.
Here is an example of how to show a warning for non-JavaScript browsers:
<!DOCTYPE html>
<html>
<head>
<title>Warning for Non-JavaScript Browsers</title>
</head>
<body>
<noscript>
<p>This website requires JavaScript to be enabled.</p>
</noscript>
</body>
</html>
This code will first check if JavaScript is enabled. If JavaScript is not enabled, the `noscript` element will be displayed. The `noscript` element will contain the text "This website requires JavaScript to be enabled."
You can also use the `if` statement to check if JavaScript is enabled and then display a warning message if it is not. For example:
<!DOCTYPE html>
<html>
<head>
<title>Warning for Non-JavaScript Browsers</title>
</head>
<body>
<script>
if (!document.querySelector('script')) {
document.querySelector('body').innerHTML = '<p>This website requires JavaScript to be enabled.</p>';
}
</script>
</body>
</html>
This code will first check if there is a `script` element in the document. If there is no `script` element, the `if` statement will run. The `if` statement will then add a `p` element to the `body` element with the text "This website requires JavaScript to be enabled."
I hope this helps!
