Learn Flexbox, Mac and Tweenlite

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.

Bash makes automation easy. Just a few lines of code can take care of repetitive tasks for you and your teammates. 

In this course, we’ll dive deep into the automation potential of bash. You’ll learn to leverage common hooks that open up interesting automation possibilities, like git hooks, adding functions and aliases in your bash_profile, and running scheduled jobs in launchd.

For example, we’ll write a git hook that checks package.json for changes, and if there are changes, the hook runs npm install for you automatically. 

Along the way, you’ll also learn:

- more advanced bash commands like exec
- syntax such as redirecting stdout and stderr to the same destination
- timesaving tricks like brace expansions

Automation is all about saving you time — and at only 52 minutes, this course is well worth yours. Enjoy!

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script.

Flexbox is a powerful way to layout HTML so that elements can grow to fit the size of their container.  It can also control how the elements are positioned within a flexed container.  

Once you start thinking in `rows` and `columns`, you can control almost any flexed layout with just a few simple flexbox layout primitives.

Get Started with Flexbox CSS Layouts

Flexbox is a wonderful tool built into the CSS specification. Using flexbox doesn't require any special framework or library, just a browser with CSS3 support. It is so awesome, and makes the arranging elements on a page almost fun!

Flexbox Fundamentals

Demystifying alignment in flexbox children

Flexbox makes it easier to create layouts that can adjust depending on the content that is added and the space available. In this lesson we look at a couple real-world applications of Flexbox in an application and website.

Using Flexbox in Websites and Applications

The flex-basis property allows us to define the dimension (along the flex-direction axis) that a flexbox child should ideally have.

safari

Did you know every Mac comes with a fantastic screen reader built-in? Learn the basics for operating Voiceover with Safari, including common key commands, the web rotor, and the help menu. We'll also set up keyboard tabbing in Safari and OSX's System Preferences, two requirements for accessibility testing that occasionally trip up users. In a future lesson, we'll compare Voiceover to Windows screen readers, since they work quite differently.

Flex-basis lets us set the ideal dimensions for a flexbox child, but flex-shrink lets us define what should happen if there isn't enough room, and flex-grow can define what happens when there is too much room.

Using flex-shrink and flex-grow to make flexbox children resize correctly

Using the `order` property we alter the order in which flexbox children appear on the page, without making changes to the dom.

Using order to rearrange flexbox children

The flex shorthand makes it easier to declare flex-shrink, flex-grow, and flex-basis, but it sometimes has unexpected results because the defaults differ.

Combining the flexbox sizing properties using the flex shorthand

The Flexbox css spec allows for more adjustable layouts. The `flex-direction` property allows you to easily change the layout on the children of an element without making any changes to the dom, which is particularly useful when combined with media queries.

Using flex-direction to layout content horizontally and vertically

Adding flex-wrap to a flexbox container allows the items to form a grid. The content can then be aligned and distributed along the grid using justify-content and align-content.

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

AngularJS animations and TweenLite make it really easy to create cool 3d effects in your application.

React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.

react-native

React Native utilizes flexbox for layout, and you can apply styles inline, or via external stylesheets. We will learn about both approaches, and create some basic styles for a native application.

For getting your application setup, you might want to checkout [this lesson](https://egghead.io/lessons/react-react-native-up-and-running?course=react-native-fundamentals&from=react-applying-styles-in-react-native)

Amazon Web Services (AWS) is a powerful expansive cloud infrastructure platform for building modern web applications.

AWS provides services for data, presentation, authentication, security, video encoding, and much more. Offering over 175 fully-featured services from data centers globally, AWS powers a large percentage of the internet.

Installing the AWS CLI on your local workstation may be one of the biggest boosts to productivity you can make if you use AWS often. Almost all AWS features are available via the CLI allowing you to script, schedule and automate many AWS related tasks.
In this lesson, I’ll show you how to setup and verify the AWS CLI.

Installing the AWS CLI on OS X and Linux

In this lesson, we’ll learn how to change the working directory using `cd` and list a directory's contents using `ls`. We'll see how `ls`'s `-l` and `-a` flags work.

Vim is a highly configurable text editor built to make creating and changing any kind of text very efficient. It is included as "vi" with most UNIX systems and with Apple OS X.

Every programmer starting to work in a *nix environment eventually finds themselves in VIM, the default text editor. Often by mistake! Because VIM lacks the typical polished GUI of normal programs, it can be hard to discover the correct sequence of commands to even exit the program. Once you learn how to exit VIM, then the next task is to also learn how to make VIM do what you want -while- exiting!

In this lesson we cover 7 different ways of exiting VIM, whether you are in EX mode or Command (also known as Escape) mode, whether you are editing a single file or several at once.

Exit Vim

`launchd` is a robust scheduled job automation tool on macOS that allows you to schedule a task to be run at recurring times. It's macOS's take on Linux's `cron`. In this lesson, we’ll schedule a simple bash script that empties the Trash to run every Monday morning at 10am. 

First, we’ll create a plist file (a plist file is just XML) with our job configuration. In here, we’ll specify our bash script as the program to run. Then we move plist file to the `~/Library/LaunchAgents` folder. Then we’ll use launchctl to load our configuration file, which will make the job active. We'll manually activate our job to ensure it's working with `launchctl kickstart`. 

Schedule Timed Jobs on macOS with `launchd`

AppleScript is a peculiar language with a COBOL-like desire to read like English, but it's the key to automating UIs on the Mac. We'll use it together with bash to make Terminal open a new window to run any shell command.
