The viewport meta tag is super important for making websites easier to use on mobile devices. It helps web pages show up correctly on different screen sizes.

When developers use the viewport meta tag, they can set the size of the viewport to fit the device's screen. This means websites that usually work for computers can also look good on phones and tablets. By using content="width=device-width", the browser knows to change the layout to fit the user's device. This makes it easier for people to use the site.

Another key point is the initial scale. By setting it to initial-scale=1.0, the viewport meta tag makes sure that users don’t have to zoom in or out to read the text. This is very helpful for people who have trouble seeing or those who find it hard to use small buttons.

The viewport meta tag also helps with responsive design. This means that the layout can change to fit the screen size, making it easier to tap buttons and links. This way, users have a smooth experience while navigating the site.

In summary, the viewport meta tag isn't just some technical thing. It’s really important for helping everyone use websites on mobile devices easily and comfortably.
