Is it possible to add or remove class="rounded" from the image of a particular article?

I'd like to add class="rounded" to the image in the article introducing the product, while in the column, I'd like to focus on the text of the article without making the image stand out

I can't get your problem properly. By the way, if you want to remove this class from a particular post, then you need to do some tweaks with Hugo. You can set if condition on the class, so when you enable it on the post frontmatter only then it will add to your post.

Sorry, I misspoke float-left as rounded.
But I can now only apply the float-left to images in arbitrary articles using the if statement!.
Thank you so much!
