Adding pseudo-elements after pseudo-elements
I'd like to apply two css ::after pseudo-elements to a single DOM element, each with a different colour. (Yes, I could wrap the DOM element in another DOM element and give each one and ::after pseudo-element, but my preference is cleaner html.)
I doubt it's possible, but wonder if someone can tell me better.
I especially doubt the possibility of chaining ::after pseudo-elements together so that one ::after pertains to another, which pertains to a DOM element, but if anyone knows how to make that happen, please do tell.
You can use a :before pseudo-element in addition to your :after - http://jsfiddle.net/BePSq/
You can't add two ::after pseudo-elements to one DOM element. You can however add an ::before additionally. Depending on what you are trying to accomplish, this may work.
You can use both the :before and :after pseudo-elements simultaneously on one DOM element. Just make sure you position them correctly. I believe :before places the psudo-element before the parent one, while :after places it after in the html. You can only use these two however and cannot add more pseudo-elements than that.
