Answer 1

Use ::selection CSS selector that select part of text is seleced. You can add your CSS property to selected text of elements.

var textarea = document.querySelector("textarea");
textarea.selectionStart = 12;
textarea.selectionEnd = 23;

::-moz-selection { 
    color: red;
}
::selection {
    color: red;  
}

<textarea>My textarea highlighted text</textarea>

Answer 2

You can't change the selection color for a textarea, you can only change it for non-input objects.

Maybe you should try contenteditable instead of textarea
