What is viewport used for?

The viewport defines the visible area of a web page within the browser window. It is necessary for:

• Responsive design: Allows creating layouts that adapt to different screen sizes of devices (smartphones, tablets, desktops).
• Content scaling: Controls how content is displayed and scaled depending on the device's size.

<!-- Meta tag for viewport settings -->
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Parameters content:

• width=device-width: The width of the viewport matches the device's width in CSS pixels.
• initial-scale=1.0: Sets the initial zoom level of the page.

Proper viewport configuration ensures the site displays correctly on all devices, improves user experience, and SEO.
