Learn Chrome, Tailwind and Tweenmax

Optional chaining ?. in javascript is a new feature introduced in ES2020. Optional chaining changes the way properties are accessed from deeply nested objects. It fixes the problem of having to do multiple null checks when accessing long chain of object properties in javascript.

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.

Meet Tailwind, a utility-first CSS framework for rapidly building custom user interfaces.

Tailwind provides us with highly compassable utility classes but leaves the design specification completely up to the user to maintain that custom look and feel to your app.

Introduction to Tailwind and the Utility First Workflow

Now that we covered fundamentals, we're going to design and implement common components that you will see in the wild. 

We'll start with a basic Vue.js application and some hard-coded data that will be displayed within the application.


Design and Implement Common Tailwind Components

The Navbar is a common component you will find yourself styling in almost any application. 

In this course, we'll style a Navbar for a mobile view with a logo and toggleable hamburger button that will contain nav links.

After building up the mobile view, we will refactor the navbar to be responsive by removing the hamburger menu from the navbar and replacing that with the links directly inline within the Navbar

Build a Responsive Navbar with Tailwind

A menu dropdown is a common component that you will build and style in any application.

In this course, we'll start from scratch, build and style a static dropdown menu and then add functionality to the component so you can open and close the dropdown. There are some keyboard accessibility topics we'll cover when adding interactivity to the dropdown. We'll use Vue in this example but these concepts will apply to any framework. 

After the drop down is fully functional and styled properly, we'll see how sometimes you need to rethink the design of a component when considering the mobile view. For this case, the dropdown is removed entirely and the links shown inline underneath the navbar content.

In this course, you'll learn how to handle responsive breakpoints, how to trigger specific element states, how to handle specificity, how to keep your bundle file size in check, and how to seamlessly extend Tailwind with your own custom utility classes.

By the end of the course, you should have a firm understanding of how Tailwind works and be able to create your own tailor-made design system and utility class CSS toolkit for your next project!

Build User Interfaces by Composing CSS Utility Classes with Tailwind

Building your web app with a fully customized design is a daunting task. If you aren't a CSS expert, applying a design style to your markup can consume hours and hours as you try to tweak pixels, align elements, and bang your head on the desk in frustration.

There are options. You can turn to a full-blown CSS framework like Bootstrap to help build your app. But, out of the box, you end up building an app that people will look at and say, "Hey there, nice Bootstrap app."

So if you want a fully custom design, you are back at step 1.

There's a middle way. An approach that gives you the freedom to apply your custom design, but in a way that greatly simplifies the CSS, providing you with core functionality without applying heavily opinionated design to your app.

This is Tailwind, a utility-first CSS framework for rapidly building custom user interfaces.

Design with Tailwind CSS is a series that teaches you how to build fully responsive, professionally designed UIs from scratch using Tailwind CSS.

Together we’ll build Workcation, a property rental app loaded with interesting details that will help you master Tailwind in no time.

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.

Debug the DOM in Chrome with the Devtools Elements Panel

This course examines the Sources panel in the Chrome DevTools, which allows you to see what files are responsible for the various things on the screen. Bundled into this panel, though, is the single most useful tool for any JavaScript developer - the JavaScript Debugger. We’ll use the Debugger to inspect JavaScript as it runs, allowing you to watch (and even interact with) the state of your application as it runs in ways that’ll blow your mind if you’ve mostly used console.log to debug your applications to this point. 

Debug JavaScript in Chrome with DevTool Sources

This course will examine the Network panel in Chrome DevTools. We’ll step through the request log, examining the various properties exposed. We’ll talk about timing, filtering, throttling and generally using the network panel to better understand the ways in which our applications exist within a connected context.

In this lesson we'll introduce Tailwind to a basic HTML project and see how it compiles into CSS with PostCSS. Tailwind can be configured in the tailwind.config.js file where you will define plugins for PostCSS to compile.

After that, we'll spin the project up with live-server and introduce styling with Tailwind utility classes. 

Set up Tailwind and PostCSS

Tailwind has variants that you can use when you want to apply styles conditionally to elements. We will start off with the `hover` and `focus` variants.

One thing to note is that not all variants are available to you out of the box (e.g. the `active` variant) to save on file size when you get started with Tailwind. Additional variants can be configured to add functionality.

We'll finish the lesson by combining and adding custom Tailwind Variants.

Conditionally Style Elements with Tailwind Variants on Hover and Focus 

Learn how to style HTML elements with Tailwinds utility classes.

We'll adjust size and positioning with padding, margin, and height as well as style text elements color, weight, and spacing through more utility classes

The Tailwind Utility-First Workflow

The @apply directive lets you compose utility classes so you can re-use common styles and not litter your html with a ton of repetitive styles.

Even when using @apply directives, it's still easy to start repeating yourself in your code. We'll use the multi-class component pattern to extract the common styles into a base class and then styling (e.g. color) can be additionally applied as another class.

Compose Tailwind Utilities with @apply

Tailwind has a set of Responsive breakpoints that you can add to any utility class. We'll see in this lesson how to apply `sm`, `md`, `lg`, and `xl` breakpoints to style according to the screen that you are targetting.
