Learn Axios, Chrome-devtools and Css

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.

Create a Landing Page with CSS Grid and Flexbox

The CSS Grid Layout introduces a two-dimensional grid system allowing both fixed and flexible track sizes to be defined. This allows for easy management of an app's layout.

You'll start with an empty HTML file with minimal global styles applied in your CSS file. You will then iteratively add sections and items to your HTML page to structure through a CSS grid. You'll learn how to control a grid's columns and rows and define the size of each respectively. 

By the end of the course, you'll have a fully responsive landing page that behaves how you expect it to on any device.

Cascading Style Sheets bring order and beauty to our applications.

Build Modern Layouts with CSS Grid

Forms are one of the most common features of a web application. They are also a common cause of headaches. The controls you use, the markup for the structural layout, and the styling all have to be considered.

What you build can look and behave differently depending on the browser being used, and how you build it can impact the accessibility of your application.

Stephanie Eckles has prepared several lessons that work through the creation of a complete form demo featuring the most common controls with a variety of attributes.

You'll create semantic fieldsets, add responsive styles without media queries, and prepare styles for accessible validation.

The demo is built with Sass and Eleventy. Don't worry if you don't have prior experience with these tools— Stephanie's code and explanations make it easy to follow along, and additional resources are available if you need them.

OpenGraph images are the images you see when you paste a link into a social platform and it "unfurls" into an image, title, and description. This happens on Twitter, Discord, Slack, and many other platforms. This collection goes over everything from designing OpenGraph images in Figma, to implementing them in CodeSandbox, to returning headless browser screenshots from Netlify Functions, and finally using Cloudinary as a write-through cache. 

You will come away from this collection with the ability to ship an API that you can use on any of your sites, and also on-demand, that can generate images for not only OpenGraph unfurls, but also for Instagram, GitHub, and more. Using headless browsers with playwright to generate our images means we get full access to all the responsive power of CSS and all the logical power of JS to handle layout, importing assets like pngs, choosing different fonts, and more.

Frontend runtime optimization is heavily impacted by rendering.  Understanding the way the JS engine and the browser work is crucial for optimizing applications and understading how to avoid performance pitfalls.
This collection explains about the Critical Rendering Path, performance bottlenecks and practical solutions.

Critical Rendering Path

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

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

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.

Developers usually have a love-hate relationship with CSS and styling user interfaces. But it is a fundamental part of creating nice-looking, adorable and successful user interfaces. In this course we will take a deep dive into the various possibilities Angular offers for styling components. We learn about the different APIs, how they allow us to conditionally apply one or multiple styles in the form of style attributes and CSS classes. We also explore the concept of style encapsulation and how it helps prevent our styles from leaking into other components.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

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.

In this course, we are going to learn about the CSS Grid Layout. The Grid Layout is a feature in CSS available in modern browsers.

CSS Grid layout is a two-dimensional layout method that gives you control over items in rows as well as columns. In this course we will look at multiple ways to divide the page into major regions with control of the size, position, and layer.

We’ll discuss all the features CSS Grid has to offer us, and how we can apply these features to real world layout-based obstacles. We’ll start with placing items on a grid by using grid-column and grid-row and progress to more complex topics such as nesting grids within grids.

Build Complex Layouts with CSS Grid Layout

Looking at snippets of CSS is a great way to learn how to use it, but some details can fall through the cracks. This course demonstrates the process of styling an application from start to finish.

We will take a basic un-styled todo-list application written in React and use CSS to get the application to look like how we want. The first steps will be to apply static styles to the app based on a mock up, then we will incrementally add user interactivity as well as make the app responsive.

Style an Application from Start to Finish

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.

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.
