MIME type的縮寫為(Multipurpose Internet Mail Extensions)代表互聯(lián)網(wǎng)媒體類型(Internet media type)，MIME使用一個(gè)簡單的字符串組成，最初是為了標(biāo)識(shí)郵件Email附件的類型，在html文件中可以使用content-type屬性表示，描述了文件類型的互聯(lián)網(wǎng)標(biāo)準(zhǔn)。

MIME類型能包含視頻、圖像、文本、音頻、應(yīng)用程序等數(shù)據(jù)。

MIME_type類型語法

media-type=type "/" subtype *( ";" parameter )

MIME示例

text/css

標(biāo)明此文件的type為text(文本)，且subtype為css(層疊樣式表)

image/gif

標(biāo)明此文件的type為image(圖像)，且subtype為gif(Graphics Interchange Format)
