Can somebody help me change the opacity of the Google Dictionary Extension for Chrome?

Question

I've tried going through the CSS, HTML, and Javascript files in the extension but nothing I try seems to work. I have very little experience with CSS, HTML, and Javascript, so I was wondering if anybody would be able to figure out how to change the opacity of the popup that comes up when you double click a word with that extension. Thanks! This is the extension: https://chrome.google.com/webstore/detail/google-dictionary-by-goog/mgijmajocgfcbeboacabfgobmjgjcoja?hl=en

If you change background:#ffc!important; in content_css_main.css to something with opacity like rgba(255, 255, 204, 0.5)!important; that should do the trick. You might have to restart Chrome (at least) or repackage it to get the change to take effect.
