Change color of specific string

Question

Does anyone know how I could change the color of a specific word if it is typed into a textarea? For instance, if the user types 'hello my friend', it would dynamically change 'hello' to green? Spent a large amount of time on google, and could not find anything very related. Thank you.

Answer 1

textareas aren't designed to be selectively colored.

Answer 2

You can't do it in a textarea field because its only content can be text, not HTML. You'll have to use an editable DIV or something, and then replace the word in string with <span>word</span> and apply a CSS class to the SPAN.
