Hi syedrazi,

 

By default editor will remove the <style> target. Please set  EnableStripStyleTagsCodeInjection="false", it should fix the problem of the html content above.

 

 <CE:Editor ID="editor1" runat="server" EnableStripStyleTagsCodeInjection="false"
            EditCompleteDocument="true">
        </CE:Editor> 

 

Regards,

 

Ken
