width=device-width, initial-scale=1

This is a meta tag that is commonly used in HTML to set the width of the viewport to the width of the device that the website is being viewed on. The "initial-scale=1" part of the tag sets the initial zoom level of the page to 100%, meaning that the content will appear at its natural size without any zooming or scaling applied.

This meta tag is important for ensuring that a website is optimized for mobile devices, as it allows the content to be displayed in a way that is easily readable and navigable on smaller screens. Without this tag, a website may appear too small or too large on mobile devices, making it difficult for users to interact with the content.
