Base64, which can be identified as one of the data URI scheme types.

Data:text/plain, Text data
data:text/html,html Code
DATA:TEXT/HTML;BASE64,BASE64 encoded HTML code
DATA:TEXT/CSS,CSS Code
Data:text/css;base64,base64 coded CSS Code
Data:text/javascript,javascript Code
DATA:TEXT/JAVASCRIPT;BASE64,BASE64 encoded JavaScript code

Picture +base64 is a way to quickly load pictures, and it saves a lot of bytes from the back end.
However, IE6 and IE7 do not support this approach.
The wording is as follows:
XADFASDFASDFASDX let this heap represent a picture of the Base64 encoding.
This thing is actually very old. Today I came up with a compatibility issue and decided to make it clear. But I found several ways, all related to MHTML.
This is a very hack way, do not recommend this, there is the asynchronous request back data, so feel very bad play.
If not compatible, you can only think of other methods.
Because to make the picture is a two-dimensional code, so re-agreed interface, by JS directly generated two-dimensional code. So other problems arise. JS generate two-dimensional code components to one.
And then it's done.
