With the interest in ESP8266s, and the need to shove your data onto the interenet, I couldnt put off learning the basics of HTML any longer.

But at the newbie stage I am at, it became very tedious to modify the code, upload it to the ESP, and then check if the page displayed as intended.

Here's an online tool I found that makes this process a breeze; simply paste your code in the left pane, and see how its going to actually look in the right pane.


Works with graphics as well.

Hope somebody finds this useful.
