I\'ve been handing a design for a webpage which I\'m trying to implement correctly. This design contains navigation elements which are partially or entirely duplicated all
It's possible using ::before and ::after.
However, it can only display text (not HTML elements). If it could display HTML elements, then there would be a major security risk...
I could possibly inject a element inside the page, with malicious JavaScript for example.
If CSS was capable of this, then CSS Userscript extensions such as Stylish could be dangerous.
