Styling

[00:00] We're going to do some pretty cool fancy multi-cursor magic right here. So I'm going to take all of these, we're going to say class, name, box, and then we'll say our box, dash, dash, these. This one's sizeless, we'll take that out.

[00:16] And then we'll say style, and the attributes are background color, background color, and that should be this. And our font style should be italic. Boom, look at that.

[00:34] And then we'll go update this one, it's not colorless, there's no sizeless class name or anything like that. But with that, holy smokes, it's magic, it works. All right, so this one didn't have a whole lot to it. Each one needs a class name, each one needs a style,

[00:49] and the sizeless colorless box should still have a class name of box, and it should still be italic, but it doesn't need a size or color. And that gets us styling with a class name and style, applying all of these awesome CSS properties

[01:08] or things to these different elements. So if you got that, good job, let's move on.

[00:00] Alright, we've got this index CSS file that has a bunch of cool styles we want to be applied to these elements. And if we take a look at our view source here, we're going to see that is included as a style sheet. Here's our href to the index CSS. So your job is to apply some of these class names.

[00:18] And there's some inline styles that we want you to apply as well. So by the time you're all done, should look something like this. So have a good time with this one. We'll see you when you're done.

Learn everything you need to be effective with the fundamental building blocks of React applications. 

The path of this workshop takes you from the fundamental API of appending DOM nodes, through React's raw APIs, to how JSX compiles into React's methods.

Once you have a firm grasp of what React is doing with creating elements, you'll learn the other tools you need to build webpages like: styling, forms, and inputs. 

But, this isn't just a native web course. 

**You'll be building a strong foundation in React.** 

Learn how to: 

- build reusable components
- leverage TypeScript with React
- catch errors with Error Boundaries
- render arrays properly with the `key` prop. 

When you’re finished, you’ll be prepared to create and use React components to build excellent experiences for your app's users.

## Hello World in JS

You'll start your journey by learning some of the history of how we went from generating HTML on the server and adding JS on top to full-fledged frameworks. 

To learn React you'll be following a similar path and begin by learning how to manually append your own DOM nodes.

I call this "going down to level up." You'll find yourself much more efficient with React if you understand the fundamentals of the DOM and JavaScript!

## Raw React APIs

Before getting into JSX, you'll learn how to work with React and ReactDOM's raw APIs. 

You'll create React elements with `React.createElement` and learn how compose your elements with calls to this function. Then, you'll render the React elements you create using ReactDOM.

## Using JSX

Once you know what React is doing under the hood, you'll be prepared to learn JSX.

This section covers more than just how to write it, you'll also use babel to experiement with how JSX gets compiled to the raw React APIs!

## Custom Components

Just like in regular JavaScript, when you want to reuse code, you write functions. If you want to share JSX, you can do that as well. 

In this section you'll learn about how in React, we call these functions "components", the special properties of these functions, and how to 

## TypeScript

> TypeScript is not making your life terrible. It's just showing you how terrible your life already is. 
 
*- Kent C. Dodds*

Getting a solid hold of TypeScript from the get-go will set you up for success. Since React components are just functions, there aren't any special considerations when applying type annotations. 

So, you'll be working on two things:

1. Improving your TypeScript skills
2. Learning the React-specific types available

## Styling

In this section you'll learn about the two primary ways to style React components:

1. Inline styles with the `style` prop
2. Regular CSS with the `className` prop

You'll also learn why React uses a `className` prop instead of `class`. 👀

## Forms

In React, there actually aren't a ton of things you have to learn to interact with forms beyond what you can do with regular DOM APIs and JavaScript.

Here, you'll learn the form markup, build an onSubmit handler, and then create a form action. 

## Inputs

There's a ton of different input types and you're going to learn a lot about them here!

You'll learn about the different text inputs, check boxes, radios, hidden inputs, how to make sure everything is properly labeled and accessible, and setting default values and default checked boxes. 

## Error Boundaries

This is something you want to learn early on. Sometimes things go wrong and we need to handle errors and display useful information to the user. 

An ErrorBoundary component doesn't ship with React by default. So, you'll be importing one from react-error-boundry and then learning how to compose it, and then give the option to the user to reset. 

## Rendering Arrays

In React you can render arrays of elements. One of the tricky parts about it is the `key` prop. 

In this section, you'll learn in detail why React needs the `key` prop to keep track of elements and the nuances of the value that is used. 

Finally, you'll learn a cool trick where the `key` prop is used as a mechanism for resetting elements in the DOM!


Starting with an HTML file and a script, you'll learn React API to build components and manage forms. Learn the fundamentals of building on the web with React.
