How to detect if JavaScript is disabled in a browser

Today we're going to discuss a very important topic – how to detect if JavaScript is disabled in a browser.

This is an essential skill for web developers, as it allows them to create websites that work even when JavaScript isn't enabled.

The simplest way of detecting whether or not JavaScript is enabled in a browser is by using the <div> tag with the class pagecontainer and adding some CSS code inside of it.

The following example will display something only if JavaSripts are enabled.

<div class="pagecontainer">
    JavaScripts are enable!
</div>  
<noscript>  	
  <style type="text/css">    		
    .pagecontainer {display:none;} 
  </style>     	
  <div class="noscriptmsg">       
     Javascripts are disabled!      
  </div>
</noscript>

In this example, we have used two tags: div and noscript which contain different messages depending on whether JS was detected or not.

If you open your page in a browser where JavaScript has been disabled, then you should see the message Javascripts are disabled. Otherwise, JavaScripts are enable! will be displayed instead - indicating that everything works fine with JS being present on your website's visitor side.

We hope this tutorial gave you some insight into how to detect if Javascript has been turned off in browsers so that your webpages can still function properly even without its presence - providing users with great experiences regardless of their settings choices!
