I found this cool online html editor . If you code html with Wordpad , you'll like this . You just paste your code in the top and it shows up just like IE in the bottom . You see all changes immediately . Then just paste it back into your document when finished .
Here is a screenshot

When you first go to the site , notice there is a typo . No space between "textarea" . Put your cursor there and add a space , you will see it move on the bottom . The center bar is movable too .
