Modifying card to render everything in one page without having to scroll

[vineetparikh]

I created a custom tag for an in-browser terminal-looking chat window which I want to render on a page, but when rendering the window, it looks like the terminal chat window is cut off as opposed to rendering the whole thing, even though I thought I configured it to take up a larger portion of the card. It looks like this is because the "card" doesn't increase in height to fit the size of the content while ensuring the licensing section is near the bottom, even if on other posts it seems to happen. I've attached two images below.

What modifications can I make so the card doesn't require a scroll bar while still looking natural (similar to longer posts in Hexo which don't have a scroll bar)?
