A Collection of Page Transitions A showcase collection of various page transition effects using CSS animations. View demo Download source Today we’d like to share a collection of creative page transitions with you. We’ve put together a couple of animations that could be applied to “pages” for creating interesting navigation effects when revealing a new page. While some effects are very simplistic, i.e. a simple slide movement, others make use of perspective and 3d transforms to create some depth and dynamics. Please note that this is just for showcasing some interesting effects and for inspiration. The CSS animations are divided into different sets, depending on what they do. Please note: this only works as intended in browsers that support the respective CSS properties. For showcasing the page transitions, we’ve used the following structure: The perspective container is relative and we add a perspective of 1200px to it. I hope you enjoy this and get inspired to build some exciting things!
Animatable: One property, two values, endless possiblities box-shadow From: 0 0 black To: 0 150px 10px -50px rgba(0,0,0,.5) Author: @leaverou Keyframe Animation Syntax Basic Declaration & Usage For the sake of brevity the rest of the code on this page will not use any prefixes, but real world usage should use all the vendor prefixes from above Multiple steps If an animation has the same starting and ending properties, one way to do that is to comma-separate the 0% and 100% values: Or, you could always tell the animation to run twice (or any even number of times) and tell the direction to alternate. Calling keyframe animation with separate properties Animation Shorthand Just space-separate all the individual values. animation: test 1s 2s 3 alternate backwards Combine transform and animation Multiple animations You can comma-separate the values to declare multiple animations on a selector. Steps() The steps() function controls exactly how many keyframes will render in the animation timeframe. If you use steps(10) in your animation, it will make sure only 10 keyframes happen in the allotted time. The math works out nicely there. Browser Support More Resources
Sass: Sass Basics Before you can use Sass, you need to set it up on your project. If you want to just browse here, go ahead, but we recommend you go install Sass first. Go here if you want to learn how to get everything set up. PreprocessingPreprocessing permalink CSS on its own can be fun, but stylesheets are getting larger, more complex, and harder to maintain. Once you start tinkering with Sass, it will take your preprocessed Sass file and save it as a normal CSS file that you can use in your website. The most direct way to make this happen is in your terminal. You can also watch individual files or directories with the --watch flag. sass --watch input.scss output.css You can watch and output to directories by using folder paths as your input and output, and separating them with a colon. sass --watch app/sass:public/stylesheets Sass would watch all files in the app/sass folder for changes, and compile CSS to the public/stylesheets folder. 💡 Fun fact: Sass has two syntaxes!

An Introduction To CSS3 Keyframe Animations Advertisement By now you’ve probably heard at least something about animation in CSS3 using keyframe-based syntax. The CSS3 animations module1 in the specification has been around for a couple of years now, and it has the potential to become a big part of Web design. Using CSS3 keyframe animations, developers can create smooth, maintainable animations that perform relatively well and that don’t require reams of scripting. In this article, we’ll cover all the important parts of the syntax, and we’ll fill you in on browser support so that you’ll know when to start using it. A Simple Animated Landscape Scene For the purpose of this article, I’ve created a simple animated landscape scene to introduce the various aspects of the syntax. (NOTE: Versions of Safari prior to 5.1 have a bug that prevents the animation from finishing correctly. I’ll describe the CSS related to only one of the elements: the animated sun. The @keyframes At-Rule Here’s the @ rule we’ll be using: @keyframes sunrise { }
CSS Animations with only one keyframe This is a very quick tip, about a pet peeve of mine in almost every CSS animation I see. As you may know, I’m a sucker for reducing the amount of code (as long as it remains human readable of course). I demonstrated a very similar example in my “CSS in the 4th dimension” talk, but I recently realized I never blogged about it (or seen anyone else do so). Lets assume you have a simple animation of a pounding heart, like so: You can see the problem already: the shrunk heart state is repeated twice in the keyframes (from and to). You probably know you can combine them into one rule, like so: What many don’t know, is that you don’t need these two keyframes at all, since they basically replicate the same state as the one in the .heart rule. If a 0% or “from” keyframe is not specified, then the user agent constructs a 0% keyframe using the computed values of the properties being animated. Therefore, the code could actually be as simple as:
22 Experimental WebGL Demo Examples WebGL is a web standard created to display 3D graphics in any platform that supports OpenGL. It makes use of the HTML5 Canvas element to generate graphics dynamically from script code, so there's no need to install plug-ins in the web browser. It includes some libraries that are currently in development, such as C3DL and WebGLU.
Using Custom Data Attributes and Pseudo-Elements A tutorial on how to (ab)use custom data attributes and pseudo-elements for creating image captions. In today’s tutorial I want to show you some simple CSS tricks using data attributes and pseudo-elements. The aim is to create an image caption using only an anchor and an image as markup. We’ll be exploring how to create pseudo-elements from some data attribute values and use them in a hover effect or simply show them next to the image. Using (more) semantic markup is of course what you should be doing, especially for data that is important to be shown. If you’d like to explore some fancy image caption hover effects with “real” markup, check out the Caption Hover Effects. And if you are interested in some really cool animations and transitions with pseudo-elements, then check out this article by Marco Barria: Examples of Pseudo-Elements Animations and Transitions. The demos feature some beautiful artwork by Jaime Martinez. Let’s start with the markup. Example 1: Caption next to image
CSS Overlay Techniques There are several techniques for creating overlays: from using an absolutely positioned element to outlines and pseudo-elements. In this article we are going to explore each technique's styles with their pros and cons. Design patterns, a set of best practices and techniques that aim to solve some of the most common design “problems”, are usually presented in the context of design principles. We can decide intelligently when to keep the user on the page and model his process. Lightweight overlays can be used for asking questions, obtaining input, introducing features, indicating progress, giving instructions, or revealing information. When the user interaction is only accepted in the pop-up modal, a Lightbox effect is usually applied and the rest of the page is dimmed, indicating its inactivity. The aim of this tutorial is to introduce you to several techniques that can be used to create this dimmed overlay with CSS, and determine the pros and cons of each technique as we go over them.
I miss you ♥ | Vertical align anything with just 3 lines of CSS With just 3 lines of CSS (excluding vendor prefixes) we can with the help of transform: translateY vertically center whatever we want, even if we don’t know its height. The CSS property transform is usally used for rotating and scaling elements, but with its translateY function we can now vertically align elements. Usually this must be done with absolute positioning or setting line-heights, but these require you to either know the height of the element or only works on single-line text etc. So, to vertically align anything we write: That’s all you need. It is a similar technique to the absolute-position method, but with the upside that we don’t have to set any height on the element or position-property on the parent. To make it even more simple, we can write it as a mixin: You can find a demo of it here: See the Pen Vertical center with only 3 lines of CSS by sebastianekstrom (@sebastianekstrom) on CodePen.

How To Build A CSS3 Sliding Menu It’s often best to put things away until you need them. Navigation menus are a good example. If I’m reading an article, I don’t want a large proportion of screen real estate taken with links — especially on a mobile device. In this article, we’re going to build a slide-out menu using CSS alone. If you’re using a modern browser, it will also show a lovely 3D page effect. View the CSS3 sliding menu demonstration… There are various solutions throughout the web, but I struggled to find one matching my requirements: It must use clean semantic HTML5 with no superfluous tags.It must not rely on JavaScript.It must not require additional graphics.It must work on mobile and tablet touch devices.It must degrade gracefully in older browsers (IE7+) or when specific CSS3 properties are not supported.It must look great! Open your favorite editor and let’s get coding… The HTML CSS: Article Styles The article is a little unusual because we want to apply a 3D effect when the menu slides into place.
CSS3 Animation Cheat Sheet - Justin Aguilar How it works The CSS3 Animation Cheat Sheet is a set of preset, plug-and-play animations for your web projects. All you need to do is add the stylesheet to your website and apply the premade CSS classes to the elements you want animated. The CSS3 Animation Cheat Sheet uses CSS3 @keyframes and works on all the latest browsers (that's IE 10). Add the animation stylesheet to the <head> element of your webpage: Replace css with the name of the directory where the animation stylesheet is. Add an animation class to the element you want animated: Replace slideUp with the desired animation class. For entrance animations, you need to make them invisible by adding the visibility: hidden property to the animated element: visibility: hidden; is used to hide elements before the animation is activated. The values for these animations are relative to the element's size. Adding effects Add jQuery to the <head> element of your webpage: Replace slideUp with an animation class.
CSS Positioning Review the W3C CSS standard recommendation. To use CSS for layout effectively, it helps to know how it's used to position page content. This article gives an overview of the methods and rules that govern visual rendering in the CSS2 specification. It also points out some things to watch out for. Although the specification applies to any device for displaying web pages, this article focuses on how it works in browsers. Many details are left out for the sake of simplicity. It's important to remember that a given browser may not support a given feature or may even implement it incorrectly. The Box Model To understand positioning in CSS you must first understand the box model. content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content content margin border padding content
