Gain insights into building real-world components using JavaScript. Delve into dropdown menus, auto-validating forms, autocomplete search, infinite scroll, and tooltips to tackle common frontend challenges seamlessly.

Learn to apply your introductory knowledge of HTML, CSS, and JavaScript to build beautiful, real-world components. In this course, you'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
- Medium's tooltips

You'll learn how to approach common frontend challenges, what questions to ask yourself, how to design solutions once you've thought of them, how to debug and work with mistakes, and more.

The end-goal is to empower you to look at anything you see on a website and be able to say, "I can build that!"

Intermediate JavaScript: Building Frontend Components

## Targetting the elements
We have some divs for grouping; now, let's make them targetable so we can actually do things with them. There are [a variety of ​conventions](https://codepen.io/hidanielle/post/css-methodologies-naming-conventions-and-file-structures) to follow for naming our div classes, and in the end, it doesn't matter which of them you pick -- as long as you're consistent with one.

We'll use a convention called [BEM](http://getbem.com/introduction/) for our projects since I think it's easy to understand.
