Definition and Usage
The <noscript> tag is used to provide an alternate content for users that have disabled scripts in their browser or have a browser that doesn’t support client-side scripting.
The noscript element can contain all the elements that you can find inside the body element of a normal HTML page.
The content inside the noscript element will only be displayed if scripts are not supported, or are disabled in the user’s browser.
Browser Support
The <noscript> tag is supported in all major browsers.
