HTML5-Modernizr is a lightweight, open-source JavaScript library that detects HTML5 and CSS3 features in various web browsers. It allows developers to create websites with modern features, while still ensuring that the website is compatible with older browsers.
To install HTML5-Modernizr, simply incorporate the following code into the <head> section of your HTML file:
<script src="https://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.3/modernizr.min.js"></script>
HTML5-Modernizr works by adding classes to the <html> element of your web page depending on which features are supported by the browser. Here is an example of how to use it:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>HTML5-Modernizr Example</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.3/modernizr.min.js"></script>
</head>
<body>
<h1>HTML5-Modernizr Example</h1>
<div id="message"></div>
<script>
if (Modernizr.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var message = "Your location is: " + position.coords.latitude + ", " + position.coords.longitude;
document.getElementById("message").innerHTML = message;
});
}
else {
document.getElementById("message").innerHTML = "Geolocation is not supported by your browser. Please upgrade to a modern browser.";
}
</script>
</body>
</html>
In this example, HTML5-Modernizr is used to check whether the browser supports geolocation. If it does, the current position of the user is displayed. Otherwise, a message is displayed asking the user to upgrade to a modern browser.
HTML5-Modernizr is a useful tool for developers who want to create modern websites while still ensuring that their website is compatible with older browsers. It is lightweight, easy to use, and open-source.
