How to disable syntax highlighting by default

[AaronNGray]

I am using .md's and markdown-styles to document my own language and am wanting no specified language on the ``` to produce no syntax highlighting what so ever. I am getting what appears to be randomized highlighting on random words. How do I go about disabling highlighting on the case of no specified language on the language blocks. Should this not be the default case anyway ?

For example of random highlighting occuring :-

I would still like to be able to use the ```js for example, but want normal code blocks to be unhighlighted the same as I am getting in GitHub.

Remove all css from the css files of the default style used would do that, like I have these file in assets/css folder, so you may remove all css from there?.
