What does Mobile version mean?

The mobile version is the form of a website or e-shop adapted for use on smartphones and other devices with smaller screens. Content, navigation, buttons, images and forms are adjusted to remain easy to read and easy to control by touch. Today, responsive design is most commonly used, which automatically changes the page layout according to the display size, instead of creating a separate mobile website. A good mobile version should be fast, clear and retain all important features. In e-commerce, it is essential especially for comfortable product browsing, working with the cart and easily completing an order on a phone.
