Recently I began experience some difficulties to insert "raw" HTML code in blogger-window. The problem was that HTML code did not show up under browser as HTML code because all tags were executed. I still want to show some code in my blog. Therefore I searched Internet for the answer. And I found very easy and appropriate solution: replace all "<"-signs to and all ">"-signs on
I tested and it works. Now I can insert some "raw" code. Thanks Mr.Internet for a good tip.
