Styling Form placeholder text when Typing

Hi!

I have been trying to look into how to change the colour of the placeholder text while typing in forms, and I could not find a solution.

Just to clarify, I do not want to recolor the “placeholder text” which can be styled with “placeholder state”. I wish to style the place holder text when typing.

I saw this link: Styling a web form - Web design tutorial - YouTube, which says to type something in preview mode and jump back in to change it, but it does not work for me as when I change preview mode, the text disappears. In the comment section on YouTube I have seen other people having trouble with this.

Could you please help out and point me to the right direction?
