I created a post containing <img class="xyz" src="..." />, but when Discourse renders the post, it puts my image in a lightbox-wrapper and discards my CSS class, so I can’t style it using that class.
Is this a defect in the theme? in Discourse? Is it just something I need to make peace with not being allowed to do? I only want to style certain kinds of images in this particular way and I prefer not to write custom CSS that depends on CSS classes whose names I don’t control.
Thanks.
Hi @jbrains 
Discourse only accepts an array of allowed HTML tags and attributes. Adding an arbitrary class to an element isn’t possible without creating a plugin.
However, if you want to customize an image inside your post, you can put it inside a [wrap] tag or something similar.
Have a look at Customize posts' contents with your own styles
I understand and I did something that I can be satisfied with. Thank you.
