How to fix bad CSS in Ghost?

Anyone knows if we can fix bad css that shows up in this speedtest? Casper the default theme is really fast. Plus I noticed when I installed Crisp (livechat), it gets really worse so I deactivated it. But a fix would be cool so I can chat with readers.

Looks like it’s coming from a hidden iframe from hotjar. I wouldn’t be too concerned about it, it’ll make minimal impact in this case. It’s the nature of embeds like this, they come with additional JavaScript and CSS that can sometimes affect the overall performance of the page. It’s a tradeoff for convenience :blush:
