How do I make a textbox that has a grayed out content, and when I click on it to enter text, the grayed out portion, it disappears and allows me to enter the desired text?
Example:
A "First Name" text box. The words "First Name" are inside the text box grayed out, when I click, those words disappear and I write my name in it.

The disabled="disabled" parameter is the standard way to do this, and you could use something like jQuery to dynamically disable all of the form elements contained in a fieldset (Which is the standard way of grouping related form elements) on the fly.
If you want to set a hint for text area or input field, then use the HTML placeholder attribute. The hint is the expected value, which gets displayed before the user enters a value, for example, name, details, etc.
document. getElementById("color"). disabled = true; edit — oh also, as pointed out by others, it's just "text", not "TextBox", for the "type" attribute.
Chrome, Firefox, IE10 and Safari support the html5 placeholder attribute
<input type="text" placeholder="First Name:" />
In order to get a more cross browser solution you'll need to use some javascript, there are plenty of pre-made solutions out there, though I don't know any off the top of my head.
