Build a dropdown menu, tooltip, auto-validation form, and an infinitely scrolling list, similar to the Twitter news feed.

Become a Front-end Developer

In this module, we’ll learn to apply our introductory knowledge of HTML, CSS, and JavaScript to build beautiful, real-world components. We'll go through the process of developing several complex components, including eBay's dropdown menu, Gmail's auto-validating form, Google's main autocomplete enabled search, Twitter's infinitely scrolling list, and Medium's tooltips.
We'll also learn how to approach common frontend challenges—what questions to ask, how to design solutions once we've thought of them, how to debug and work with mistakes, and more. By the end of this module, you’ll have acquired sufficient skills to build any website.

Projects

The back end performs a lot of the difficult work of actually computing how to complete what you’ve typed, but we’re building the frontend component, so we’ll build upon a mock server.

We're going to be building a relatively straightforward but widely used version of autocomplete search: Google's main search.

In this lesson, we'll learn what the autocomplete functionality is and give a layout of the rest of the chapter
