Origami keep changing html codes

this is my second page’s URL:
http://www.mlstrateji.com/fethullah_gulen_teror_orgutu/

When i copy/paste codes to page text editor, my page look like above. But, when i click “visual”, even i do not change or add anything, all codes turn plain, all colors turn black and white. I loose all highlights, colors, bold fonts etc.
But if i publish it in text mode, without click anywhere… my codes look normal.
How can i edit my texts or pictures without lose my preferences?

Thanks
