Styling letters of a word within an input differently, possible?

Question

Wondering if this is even possible, but if I have a input containing text, for example lets say the word \'Test\' is in the input. What I would like to be able to do is change

Answer 1

You should take a look at how HTML WYSIWYG editors are build.

Basically, they

• hide the input field and display another html element with the styled content: Highlight text as you type on textarea

or

• use design mode in html: javascript Rich Text Editors

both ways are not trivial...
