To select the children of an element you can use the children()
method.
<div class="parent">
<h2>A headline</h2>
<p>Lorem ipsum dolor sit amet...</p>
<p>Praesent quis dolor turpis...</p>
</div>
Change the color of all the children of the .parent
element:
$('.parent').children().css("color", "green");
The method accepts an optional selector
argument that can be used to filter the elements that are returned.
// Only get "p" children
$('.parent').children("p").css("color", "green");
