Sizing Google Recaptchas

I was struggling today trying to get a Google Recaptcha integrated into a site. The space was smaller than the recaptcha size, and I couldn't figure out how to size it down. I found this article that explains very easily how to do it.

<div class="g-recaptcha" data-theme="light" data-sitekey="XXXXXXXXXXXXX" style="transform:scale(0.77);-webkit-transform:scale(0.77);transform-origin:0 0;-webkit-transform-origin:0 0;"></div>
