Correct, `` tags also have very specific properties that are whitelisted. Those can be found here:
[https://github.com/discourse/discourse/blob/master/app/assets/javascripts/pretty-text/white-lister.js.es6#L141-L152](https://github.com/discourse/discourse/blob/master/app/assets/javascripts/pretty-text/white-lister.js.es6#L141-L152)
That file - it is the same one from my earlier post - contains all the whitelisted markup allowed in the composer so have a look around to see what is allowed. Anything not on that list will be stripped out to prevent abuse.

The `` tag has a CSS class added to it to when the user is not logged in. That class is `anon`. You can use that class to selectively show the banners. So something like this in your post:
```plaintext
```
and this in your theme
```plaintext
html:not(.anon) .cooked [data-theme-banners] {
display: none;
}
```
and that would ensure that the element is only visible to users who are not logged in.
