Post HTML codes in blogs

If you post articles with html tags on blogspot, it will most probably give an error message as:

ERROR
"Your HTML cannot be accepted: Tag is not allowed: "

The way to get around this is to convert all the mark-ups (eg: '<' , '>') into character-entities (eg: '&lt;' for '<' ; '&gt;' for '>')

One can use online applications that perform this conversion stuff:

If formatting has to be retained, then just enclose the code inside '<pre>' and '</pre>' tags.
