The blink element is a non-standard presentational HTML element that indicates to a user agent (generally a web browser) that the page author intends the content of the element to blink (that is, alternate between being visible and invisible). The element was introduced in Netscape Navigator but is no longer supported by any modern Web browser; some, such as Internet Explorer, never supported the element at all. Despite its initial popularity among home users in the 1990s, it has since fallen out of favor due to its overuse and the difficulty it presents in reading. The tag achieved notoriety for being user-unfriendly in the opinion of many designers. Lou Montulli, often credited as the inventor of the blink element, has said that he considers "the blink tag to be the worst thing I've ever done for the Internet", although he claims he only suggested the idea, without writing any actual code. == Usage == The blink element is non-standard, and as such there is no authoritative specification of its syntax or semantics. While Bert Bos of the World Wide Web Consortium has produced a Document Type Definition that includes syntax for the blink element (defining it as a ''phrase element'' on a par with elements for emphasis and citations), the comments in the DTD explain that it is intended as a joke. Syntax of the blink element type is identical to such standard HTML inline elements as span. For example: The blink element type was first invented for Netscape Navigator and was supported in its descendants, such as Mozilla Firefox (except for the ''Netscape 6'' and early Mozilla suite browsers); it was removed in version 23.〔(【引用サイトリンク】title=Firefox 23 Release Notes )〕〔()〕 Microsoft's Internet Explorer and WebKit (the browser engine behind Apple's Safari and Google Chrome) never supported it, even in its CSS incarnation. It was also supported by the Opera Internet Browser, but support ended in version 15 when that browser switched to a WebKit-based engine. 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「Blink element」の詳細全文を読む スポンサード リンク
