title: Using Flexbox, how do I programmatically move a div?
body: <p>I have a <code>div</code> within a flex container. I need to programmatically position - change <code>top</code> and <code>left</code> - and size - change <code>width</code> and <code>height</code> this <code>div</code>. How do I do this. Flex ignores changes to <code>top</code> and <code>left</code> but does seem to accept changes to <code>width</code> and <code>height</code>.</p>
