Above the fold is the upper half of the front page of a newspaper where an important news story or photograph is often located. Papers are often displayed to customers folded so that only the top half of the front page is visible. Thus, an item that is "above the fold" may be one that the editors feel will entice people to buy the paper. Alternatively, it reflects a decision, on the part of the editors, that the article is one of the day's most important. By extension, the space above the fold is also preferred by advertisers, since it is the most prominent and visible even when the newspaper is on stands. The term can be used more generally to refer to anything that is prominently displayed or of highest priority. Above the fold is sometimes used in web development to refer the portions of a webpage that are visible without scrolling. == In web design == Above the fold is also used in website design (along with "above the scroll") to refer to the portion of the webpage that is visible without scrolling. As screen sizes vary drastically there is no set definition for the number of pixels that define the fold. This is because different screen resolutions will show different portions of the website without scrolling. Further complicating matters, many websites adjust their layout based on the size of the browser window, such that the fold is not a static feature of the page. A 2006 study by Jakob Nielsen found that 77% of visitors to a website do not scroll, and therefore only see the portion of the website that is above the fold. There has been considerable controversy about this finding with other broad studies finding the 76% of visitors scrolled vertically to some extent and 22% of visitors scroll to the bottom of the webpage. Most web design advice available today encourages designers to place important information at the top of the website, but to prioritize usability and design. Nevertheless, many web advertising companies require ads be placed above the fold. Each company tends to use their own definition of the fold. The BlogHer advertising network, for example, defines the fold as the top 768 pixels of the page. The FoodieBlogRoll advertising network defines the fold as the top 1000 pixels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Above the fold」の詳細全文を読む スポンサード リンク
