Feature requests, code highlighting

[y377]

As the current use of iframe, it seems to be loaded asynchronously, so the disadvantage is that my site has integrated code highlight, no matter how debugging, the code in the comments section is still no highlight, so the request to add a light highlight, do not need to be too complicated, if I compromise to the comments, that is, wait until it is loaded, and then perform My site comes with highlight, so the bad thing is that the body of the content contains a block of code that can not be displayed, because we have to wait until the comments are all loaded to display, will affect the reader to read the body.
