Basic Styling


I used to use Elgg, moved away to try something else, now I'm trying Elgg again. I don't remember how to do something basic: add custom CSS. I see there is a very old plugin. What's the best way to do some basic CSS styling in Elgg 3, such as change some colors?

And, while I'm posting I might as well ask - are there any content card scraping plugins out there? Besides hypeScraper. That one doesn't currently work. In other words, if you post a URL, a content card shows in its place.
