How does e-commerce work on the Jamstack? 

Jason Lengstorf and [Thor 雷神](https://twitter.com/thorwebdev) teamed up on _Learn With Jason_ to [build a serverless Stripe Checkout implementation](https://www.learnwithjason.dev/sell-products-on-the-jamstack). This collection is a cleaned up, egghead-style tutorial for selling products on a Jamstack site using Netlify Functions and Stripe Checkout.

An all-in-one workflow that combines global deployment, continuous integration, and automatic HTTPS.

It's tempting to pick up a framework which has preselected flexbox or grid as the layout tool of choice, but it's important to learn when and why to use each method. This leads to slimmer stylesheets which results in better site performance, and less likelihood for "hacks" to make one method do what the other does inherently better.

Throughout this collection, we will be progressively styling a responsive landing page template while building your knowledge on when to select grid or flexbox for any layout scenario. Spoiler alert: sometimes the best solution is using both!

The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent.

This course will walk you through the entire process for creating and deploying your first Static HTML Site. 

You will learn HTML (HyperText Markup Language), the language common to every website. HTML describes the basic structure and content of a web page. If you want to build a website or web application, you'll need to know HTML.

Additionally, you will learn how to make your website responsive using CSS media queries, add custom emojis, animations, and a "Tweet" button.

To finalize the course, you will learn how to deploy and host your Static HTML Site with Netlify, a powerful service that automates builds, deployments, and manages your websites and web apps.

HTML 5 is the structure of our web pages. It is the markup that represents the DOM (document object model).

CSS uses a global namespace for CSS Selectors that can easily result in style conflicts throughout your application when building an application using modern web components. You can avoid this problem by nesting CSS selectors or use a styling convention like BEM but this becomes complicated quickly and won’t scale.

CSS-in-JS avoids these problems entirely by generating unique class names when styles are converted to CSS. This allows you to think about styles on a component level with out worrying about styles defined elsewhere.

In this course, you will learn how to express popular SCSS (Sass) language features using latest JavaScript features. We will convert simple examples from SCSS to CSS-in-JS. As a designer or (S)CSS developer, you should be able to follow without extensive JavaScript knowledge, understanding SCSS is required though. We will not be using any particular CSSinJS libraries. Instead, we will focus on a base knowledge you need later if you use any CSSinJS library.

Sass is the most mature, stable, and powerful professional grade CSS extension language in the world.

A lot of the time, web apps are built primarily with the desktop layout in consideration, and the mobile layout suffers as a result. In this course we are going to discuss using features of user interface which are optimised for mobile devices.

We are going to discuss CSS features that make a big difference and build entire components that work great on mobile devices and browsers. We are going to take into account browser support to ensure our users are getting the experience we want them to.

More and more of our users depend on their mobile device to use our web apps. With this in mind, we are going to look at how to optimise the components we build for smaller viewports, and how to ensure our customer gets an optimised version of our web app for their device.

We are going to discuss different ways we can view, test, and debug our web app in a mobile setting so that we know what we are seeing is what our user is seeing, because sometimes a desktop browser emulating a mobile device just isn’t enough.

Learn to manage your terminal sessions and work more effectively from the command line using tmux. If you use the command line at all, tmux can make your life easier.

tmux bills itself as a terminal multiplexer. It allows you to wrangle multiple terminal sessions from one window. Instead of keeping track of many terminal windows yourself, you can use tmux to create, organize, and navigate between them. Even more importantly, tmux lets you detach from and re-attach sessions, so that you can leave your terminal sessions running in the background and resume them later. This is especially useful if you're working on a remote server: you can set up a persistent session that will continue running when you close your laptop. You can even share a tmux session to facilitate pair programming.

It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal.

It’s really fun to work with graphics when building apps and websites, but how do you get started? HTML5 has a technology called **Canvas** that lets us draw graphics to our screens. We can do everything from making basic shapes to creating complex interactive games and animations!

 In this course, we will learn the basics of using **Canvas**. We’ll start by learning how to create a canvas on an HTML page. Next we will learn how to draw and style with fills and strokes. Finally, we will add interactivity to canvas elements.

Have you ever wished for access to conditionals or iteration when writing styles? How cool would it be to use functions to write styles? SCSS has that and more! SCSS is a superset of CSS. Any valid CSS is SCSS, they even have the same syntax. SCSS borrows features from other languages to write smarter, reusable and more readable styles. This course will focus on how to use SCSS’s more useful features, compare them against each other and assess when their usage is appropriate.

Learn the Best and Most Useful SCSS

In this course, we will dive into a number of different ways we can create, optimize and integrate an SVG icon set. There are pros and cons to each method, so we’ll dissect each approach so you can make an informed decision for your project. We will learn how to use build tools to automate the process of creating, manipulating and optimizing icons. We’ll take a look at how to use CSS to manipulate styles on an SVG and even how to integrate your SVG icons in a React project.

Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files.

In this course we’ll take a deep look at the Elements panel in the chrome devtools. We’ll step through each button and tab on this panel and discuss how to use them to interact with your web application as it runs.

The Chrome Developer Tools (DevTools for short), are a set of web authoring and debugging tools built into Google Chrome.

Accessibility (or a11y) is an important but often neglected in the world of web development. Many developers find themselves coding user interfaces without any knowledge of keyboard or screen reader requirements. 

The fact is that accessibility doesn't happen by accident. Often it is seen as too hard or time consuming. This doesn't have to be the case. By following a handful of high-value patterns and practices, we can open our web apps to humans that otherwise wouldn't be able to interact with them at all.

This course will introduce you to accessibility through hands-on, technical examples that are way more effective than reading 10-year-old static web content.



WAI-ARIA, the Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies.

Skeleton screens show users that content is loading, offering a vague preview of how content will look once it fully loads.

CSS Animations are crucial for the perceived performance purposes since it shows for the user the content is loading by using animations as feedback for whoever is accessing the page. 

Follow the steps in this course and you will learn how to create a beautiful and pleasant Skeleton Loader for your web app using CSS animations, focusing on Web Accessibility and Web Semantic.

For small viewports, we want to save bandwidth and we may be dealing with slow speeds; so it's very important that images' filesizes are not too big. In this lesson, we are going to cover how to show a different-sized image than the one seen on desktop.

Show Images of Differing Resolutions Depending on the Viewport Width with srcset

For small viewports, we may want to show a variation of the desktop image. A very common use case of this is a cropped, smaller version of the desktop image. In this lesson, we are going to discuss showing a cropped version of the desktop image, but only for smaller viewports.

Show Different Variations of Images Depending on the Viewport Width using Art Direction

The DOM can be a bit tricky when it comes to typing. You never really know exactly what you're going to get, so you have to educate your codebase into what you know you're using. This is done using Type Assertion where TypeScript types know they're a certain type, but you give it additional information so you can access the properties and methods that you know will be available.

Frontend developers tend to write quite a lot of HTML (or JSX). This is why it's important to be able to optimize time spent writing `<div></div>` manually to use the cognitive resources for more challenging tasks. 

Modern editors such as VS Code have **emmet** plugin built in which allows us to write HTML structure much faster due to the fact that it allows us to quickly create nested structures, multiple elements, siblings etc. In this lesson we are going to learn how to use **emmet** to write HTML more efficiently.
