You cant change color of the words in text area but you can highlight them none the less but a range of words can be highlighted. You can use <p> tags to highlight if you wish

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

See you cant do that into textarea cause it is a textbox and if you will change color(using some CSS) then the whole of the color gets changed
