[Orgmode] How to remove the automatically generated css codes from exported HTML file?

[Larry . Liu]

 Hi, 

I want to remove the css style codes generated automatically by Org-mode in the exported html file, I have set the variable style for html export and itself works fine, but the css definition generated by Org-mode automatically doesn't get removed, and it affects the display of exported file, how can I remove it? 

Thanks :)
