Well, ehm… Thank you for the feedback I guess?

I appreciate your clarification: you mean that the logic part of conditional appearance should be handled by, for example, changing a property on an HTML node, and styling that property in CSS, did I get that right?

If I may offer some feedback in return, I would recommend you work on your phrasing. Insulting people can easily lead to being ignored or having low-value interactions. Asshole. 😉
