Base64是一种编码类型，允许您放置任何类型的可能包含特殊字符的数据导致解析错误）到代码中，只是数字和字母。
http://en.wikipedia.org/wiki/Base64
Base64 is a type of encoding that allows you to place any type of data that might have special characters in it (which would cause errors in parsing) into the code as just numbers and letters. http://en.wikipedia.org/wiki/Base64
数据：image / png; base64，是一个键，告诉浏览器以下字符串包含一个编码版本一个图像。不是从远程URL加载图像，而是直接包含在CSS页面中。浏览器将该字符串解码为图像文件。 http://zh.wikipedia.org/wiki/Data_URI_scheme
The sequence, data:image/png;base64, is a key that tells the browser the following string contains an encoded version of an image. Instead of loading the image from a remote URL, it is included right into the CSS page. The browser will decode that string into the image file. http://en.wikipedia.org/wiki/Data_URI_scheme
