Simultaneously toggling 2 divs in 1 container + 2 in another container
<p>I'm not sure how to search for this: on a gallery page I want to be able to toggle the image between its original size and 2x by clicking on it <strong>but also</strong> by clicking a zoom button in another container which changes state (indicating you can either zoom in or out in concordance with the image div current state)</p>

<p>I got as far as toggling the image by clicking it or the button but I don't know how to also toggle the button.</p>

<p>Thanks.</p>
