The phrase "line website" is a term used to describe websites that are specifically designed for mobile devices, particularly smartphones. These sites are optimized for smaller screens and have simplified navigation, often using fewer words and larger buttons or icons. They may also use features specific to mobile devices such as touch-to-call or touch-to-map functions. The goal of a line website is to provide an easy-to-use experience for users on the go who are accessing the site through their phone's internet browser, rather than downloading and using a dedicated app.
