Above the fold refers to the content that is immediately visible to a user on a webpage before scrolling. It originates from newspaper terminology (the top half of the front page) and in web design it means the important content or interface elements that users see first. Below the fold is the content that lies further down the page and requires scrolling to view. In UX design, it’s often recommended to place critical or highly engaging information above the fold (for example, a main headline or navigation menu), while supporting or detailed content can be below the fold. This ensures key messages or actions catch the user’s attention without extra effort.
