Well you can define CSS styles to do that... Also, if you have the CSS inline, then you can use <cms:editable>...</cms:editable> tag to change the message contents too...

Yes this can be achieved using a javascript!!!
The JScript can help you in dynamically displaying the message without reloading the page... For Example: You have a password and a confirm password field, so unless the password and confirm password match, there can be a message displayed "Passwords donot match" the moment the text box comes to focus. And once the passwords match, the message can be changed to passwords match...
