Document.getElementById() ??

[CodeDeveloperOM]

HTML5 canvas

I have a movie clip

var img = container.document.getElementById("img").getElementsByClassName("text_input_css");
container.style.width = newWidth;
container.style.height = newHeight;

use

document.getElementById("img");

if you have an element with id = img

the css is irrelevant.

and use

document.getElementsByClassName("text_input_css);

if you have elements from that class in your html
