Hi Jason,

You have a lot of ways to achieve this! I'll show you what it's like in my own theme.

In my theme editor on the Article page, I have {{article.body}} inside of a div with the classes "article-body" and "markdown":

{{article.body}} renders the entire article, including the images I placed with the article editor. If I go to any of my articles and use my browser's 'inspect' tool (right-click > inspect) I can see that there is indeed an image inside my "article-body markdown" div:

So now I need to go into my css and figure out how to target the image so I can give it a shadow. I believe the original theme I built on top of used "markdown" as the go-to classname for these kinds of edits, so I'll do just that. Here's the css selector:

This is selecting all img tags inside of the "markdown" class. Here's my shadow edit. I went ahead and targeted every single browser I could think of (except older opera versions, woops!), but really all you'll likely need are the ones I underlined:

Now if I preview my changes, I can see all my article images have shadows!

I hope this helps. Let me know if you'd like to know more
