You can't apply styles directly to text nodes, and you don't set styles as attributes on elements. They need to go on the
styleobject on the element. – cookie monster Commented Mar 26, 2014 at 20:20

Reset to default 6You would normally have to use CSS properties, however, text nodes cannot have CSS properties applied to them. You therefore need another container element:
You can choose any container element you wish, e.g. div, span, etc. It just needs to be capable of containing a text node. Having an element then allows us to access the styles property and set various styles (the color attribute in your case).
→ jsFiddle
function create_text(){
var mydiv = document.getElementById("mydiv");
var container = document.createElement("span");
var text = document.createTextNode(" New text to add.");
container.appendChild(text);
container.style.color = "red";
mydiv.appendChild(container);
}
Further note:
the order of the color assignments and calls of
appendChildis arbitrary. The following would also be possible:function create_text(){ var mydiv = document.getElementById("mydiv"); var container = document.createElement("span"); var text = document.createTextNode(" New text to add."); container.appendChild(text); mydiv.appendChild(container); container.style.color = "red"; }
mydiv.style.color = 'red';
or just in css
#mydiv { color: red; }
if you have other elements inside the div that you don't want to be red, you'd need to wrap the new text in a span or div or another element before appending.
with jquery this would be super easy:
$('#mydiv').append('<span style="color:red">this is new text</span>');
If that's everything in your div, you could try
document.getElementById("mydiv").style.color="#ff0000";
