Advanced & latest versions of browsers support transparent PNG by default. i.e. Internet Explorer 7, New Firefox, Safari and Opera etc. For IE 6 another version of this script works fine in which I gave you an example how to implement transparency in PNG for web pages. But what about background image and what if you have older browser like IE 5.5 etc.
We will be needing a js file and a page containing form input field to do this task. What we are planning to do is, The input field contains default value. Onclick default value disappears and allows the user to insert text. If the user types anything it remains there but if he does not write anything and clicks at next input field than the default value reappears in previous field.
