The new Relative Locators in Selenium 4 allow developers to locate elements on a web page based on their visual placement relative to other elements. This approach enables more natural language descriptions of elements, making it easier to identify and interact with specific elements on the page. The available locators include `above`, `below`, `toLeftOf`, `toRightOf`, and `near`, which can be used to locate elements based on their position relative to other elements. This feature provides a more intuitive way of interacting with web pages, especially when dealing with complex layouts or dynamic content.
