jquery selector questions

if we can access an crazy nested element of the page with css like

ex: .class anotherClass:nth-child(3n+3) why cant we do that when we select a dom element with $('.class anotherClass:nth-child(3n+3)');

unless im just crazy and this hasnt been working and ive been forced to use the jquery selectors like .children .siblings etc. and also i guess can someone explain to me the official can-do's and cant do's of element selection with jquery?

Hi Ryan,

I think this codepen demo is doing what you think you can't do: http://codepen.io/anon/pen/ajgEF

Do you have a specific example of what's not working for you?

It depends on what you're trying to do but .children() and .siblings() still have their uses.

Some methods only act on the 1st element in a set of matched elements. Is it possible that you used one of those methods and it led you to believe your selector wasn't selecting multiple items?

Also, to answer your final question, I believe any valid css selector can be used to select elements with jQuery.
