With the techniques that we covered in this chapter, we should now be able to locate sets of elements on the page in a variety of ways. In particular, we learned how to style top-level and sub-level items in a nested list using basic CSS selectors, how to apply different styles to different types of links using attribute selectors, add rudimentary striping to a table using either the custom jQuery selectors :odd and :even or the advanced CSS selector :nth-child(), and highlight text within certain table cells by chaining jQuery methods.

So far, we have been using the $(() => {}) document ready handler to add a class to a matched set of elements. In the next chapter, we'll explore ways in which to add a class in response to a variety of user-initiated events.
