HTML Input - already filled in text

The value content attribute gives the default value of the input element.

- http://www.w3.org/TR/html5/forms.html#attr-input-value

To set the default value of an input element, use the value attribute.

<input type="text" value="default value">

All you have to do is use the value attribute of input tags:

<input type="text" value="Your Value" />

Or, in the case of a textarea:

<textarea>Your Value</textarea>
