Data URI scheme allows us to include data in a webpage using inline-code, which can be used in Html, CSS, and Javascript.
Data URI scheme is often used to embed images into webpages. It is used as follows:
The data URI
First, prefaceIn Friday, the company's internal any Topic Conf. I shared this topic with my colleagues, some colleagues said this useful, some colleagues said this is useless, and later extended to the topic of website performance, we discuss the intensity of this topic is also good. In this article, regardless of whether it is useful or not, just record theoretical knowledge. Also hope that everyone together to share the actual combat experience Ah!Second, start with the HTTP URI schemeFor "htt

spacing: In a set of coding systems, any valid encoding becomes the minimum number of bits that must be changed by another valid encoding.
If the minimum code distance of parity is 2, this is because the minimum need to change two bits can not change the original number of the parity of 1, thereby passing the parity.

probability of the next character based on the previous character exists in the mind of the audience, which is more suitable than the adaptive model used in computers.In addition to the number of occurrences of characters, the audience can also guess their language experience.
Encoding
Through the model, we have determined the number of bits to be encoded for a symbol. The problem now is how to design an encoding
, the 100,000th character of Unicode has been adopted and recognized as one of the criteria), a set of code diagrams that can be used as a visual reference, a set of encoding methods and a set of standard character encodings, a set containing superscript words, Enumeration of character attributes such as subscript characters. The Unicode organization (the Unicode Consortium) is operated by a non-profit organization and dominates the subsequent develop

The previous study summed up the usual development of the various data encryption methods, the final will be encrypted binary data for BASE64 encoding, played a two times encryption effect, in fact, Base64 from the strict sense is not a cryptographic algorithm, but a coding algorithm, Why use BASE64 encoding?
