20+ Html Resources for Web Developers in 2021

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

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.


Optimize User Experience for Mobile Devices and Browsers

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.

Create Graphics with HTML Canvas

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 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.

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

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.

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.

HTML5 includes powerful drawing APIs that allow you to use the `canvas` element and JavaScript to draw whatever you want, directly on the page.

The playlist walks through the entire creation and deploy of patio11bot.com!  It starts as a very simple HTML page locally, and we add custom fonts, emojis, animation, a "Tweet" button, and we make it responsive!

Then we deploy it online (for free!) with Netlify.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

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.

Techniques to improve your CSS, Sass, and HTML implementations for everyday scenarios.

Cascading Style Sheets bring order and beauty to our applications.

ASP.NET Core SignalR can push events from the server into your Client Application. In this video we will build a client side Todo app with Angular which consumes events from a ASP.NET Core SignalR backend to see how we can consume and synchronize data between our client side Angular Applications.

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.

Work with DOM Elements in TypeScript using Type Assertions

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.

Efficiently write HTML and JSX using Emmet

In this lesson, we will take a look at the syntax of CSS variables. We’ll explore what the root scope is and how is it used, it's syntax. We’ll also look at the basic syntax required to use css variables.


Root scope and Syntax - CSS variables

What's in a name? In this lesson, I'll explain the concept of naming interactive elements for screen reader users, including forms, buttons, and links. You'll learn how to debug accessible names and descriptions using the Chrome Accessibility Developer Tools (previously a Canary experiment, now in Chrome), using multiple labeling techniques. We'll also listen to the effects of proper accessible names and descriptions in Voiceover and Safari.

For more information and the nitty-gritty browser implementation algorithm, refer to WAI-ARIA 1.1:

"If you can't measure it, you can't improve it." The first step when doing performance work is to measure meaningful metrics to establish a baseline for improvement. In this lesson, we'll measure Time to First Contentful Paint, a user-centric performance metric. We'll first create a PerformanceObserver object and explore the information it captures. Next, we'll send that information to Google Analytics to track FCP over time. Lastly, we'll discover why PerformanceObserver is one of the few bits of Javascript that rightly belong in the head of your document.

Instead of using divs to create a Hamburger Menu, we are going to improve the accessibility using Semantic HTML.

You'll see that a simple adjustment from a `div` to a `button` allows users to navigate our menu with their keyboard.

Use Semantic HTML to Improve Hamburger Menu Accessibility

In less than two minutes, this lesson will teach you how to create a barebones html file, with only a title and a single line of content.

Write Your First HTML Page

While you can write code with a plain text editor, many people opt for something more feature-rich. Visual Studio Code is a free code editing application that works for Mac and Windows. One of the things that makes VSCode so popular is its huge library of extensions that make writing code a breeze. In this lesson, we will install Visual Studio Code along with Live Server and Auto Tag Close extensions.

We'll be building www.patio11bot.com from start to finish as a staic HTML document - so the first step is to setup a mini web server, so that we can view the webpage locally.

There are three easy ways to do that:

`// python 2:`

`> python -m SimpleHTTPServer 8000`


`// python 3:`

`> python -m http.server 8000`


`// node:`

`> npm install -g http-server`

`> http-server`
