What do the terms 'above the fold' and 'below the fold' refer to in web design?

The terms 'above the fold' and 'below the fold' are used in web design to describe the placement of content on a webpage in relation to the user's initial view. 'Above the fold' refers to the content that is visible to users without any need for scrolling, which typically includes the most important information, headlines, or calls to action. This is crucial for capturing user attention quickly, as many visitors may not scroll down the page.

Conversely, 'below the fold' signifies the content that is located further down the page, requiring users to scroll in order to view it. This content is still important but may not receive as much attention as what is placed above the fold. By understanding this distinction, web designers can strategically place key information in the 'above the fold' area to enhance user engagement and improve the effectiveness of the website.
