Just-add-water CSS animation

Installation

Install with npm:

npm install animate.css --save

Install with yarn:

Getting started

You can find the Animate.css documentation on the website.

Accessibility

Animate.css supports the prefers-reduced-motion media query so that users with motion sensitivity can opt out of animations. On supported platforms (currently all the majors browsers and OS), users can select “reduce motion” on their operating system preferences and it will turn off CSS transitions for them without any further work required.

of font-size for preformatted text. The duplication of monospace is
intentional. Source.

sub, sup

Normally, using sub or sup affects the line-box height of text in all

CSS only

Bulma is a CSS framework. As such, the sole output is a single CSS file: bulma.css

You can either use that file, “out of the box”, or download the Sass source files to customize the variables.

There is no JavaScript included. People generally want to use their own JS implementation (and usually already have one). Bulma can be considered “environment agnostic”: it’s just the style layer on top of the logic.

Browser Support

Bulma uses autoprefixer to make (most) Flexbox…

Simple loading spinners animated with CSS. See demo. SpinKit only uses (transform and opacity) CSS animations to create smooth and easily customizable animations.

Usage

• Add spinkit.css or spinkit.min.css to your project (or copy-paste the CSS that you need for your spinner—there are no dependencies between spinners, no shared classes, and no shared animations, etc, so it should be fairly straight-forward to extract only the code that you need)
• Add a spinner to your project by copy-pasting HTML from spinkit.css or examples.html
• Add the sk-center utility class to the spinner to center it (it sets margin to auto)
• By default, the width and height of all spinners are set to 40px. background-color is set to #333.
• Configure the spinner by overwriting the CSS variables, primarily --sk-size (spinner width & height) and --sk-color (spinner color). If you need broader browser support, remove the CSS variables.

A showcase of problems once hard or impossible to solve with CSS alone, now made trivially easy with Flexbox.

View Site

Viewing the Site Locally

The Solved by Flexbox site can be built with Node.js. If you have Node.js installed on your system, you can run the following commands to build and serve a local copy.

# Clone the git repository and cd into the cloned directory.
git clone https://github.com/philipwalton/solved-by-flexbox.git
cd solved-by-flexbox

# Install the dependencies
npm install

# Build and serve the site at http://localhost:4000
npm start

This starts up a local server on port 4000. To view the site in your browser, navigate to http://localhost:4000. If you want to use a different port, you can pass the port number as an argument to npm start:

npm start -- -p 8080

In addition to building the site and serving it locally, this will…
