Question

I see this selector

       $( 'a + .firstSection a' ).live( 'click', function(){

in my js file. What is the purpose of the + sign here?

Answer 1

From jquery doc:

Selects all next elements matching "next" that are immediately preceded by a sibling "prev". A selector to match the element that is next to the first selector.
