Fading multiple elements simultaneously - jquery

You can use the add method to get the elements in the same jQuery object:

newPanel.add(prevBtn).add(nextBtn).add(infoPanel).fadeIn(200);

Assuming that newPanel and so on are variables created like that:

newPanel = $("#newPanel");

just write:

newPanel.fadeIn(200);
prevBtn.fadeIn(200);
nextBtn.fadeIn(200);
infoPanel.fadeIn(200);
