Transitions

CSS transitions are one of the most exciting and powerful features in CSS3. They allow you to animate elements on your page without any JavaScript, giving a sleek look that is very popular with web designers. In this post we will explore how to create simple animations using only CSS.

The first thing you need to do is set up a basic HTML structure. This includes the HTML element that will be animated and also an element with some text for the animation to take place on top of. For this example we’ll use two paragraphs, one containing our heading “CSS Transitions” as well as another paragraph for content below it:

` ` ————- ————- ————— ““`———–

Let’s look at how to use CSS transitions for brilliant animations. We’ll explore three different types of common animation, and see a demo with each one.

scale up/down

rotate on hover

Steps to create a CSS Transition:

In this section, I will be teaching you how to use css transitions. A transition is the change in values and properties of an element (or its corresponding presentation) over time from one value or style state to another. Transitions are created by using animation timing functions that define when something should happen over a particular period of time, e.g., linear, ease in/ease out etc. You need three things for every transition: the property being transitioned; the starting value for that property at the beginning of the transition; and the ending value for that property at the end of the transition.” What does all this mean? Well

First we need to set the keyframes that will animate our element using transition:set(). This sets two points in time where an element has changed state – it can also be called a “state machine”. In this example I’m going to want my box to change from being hidden by default, then after 300ms have elapsed, the opacity is changed over 500ms until fully visible. After another 400ms I want the content outside of my box (in this case just black text)to fade out.

We’ll then attach the transition to our element using a classname like this: .transitioning { opacity: 0; transform: scale(0); } **If you want it to animate over time, use an animation name from css such as “transform” or “opacity”. By default your transitions will be set at a duration of 300ms for each keyframe (or state) – which is usually just fine! You may also specify different speeds in milliseconds by adding more properties. In this example I’m going to go with 400ms and 500ms respectively. The text outside my box fades out after 800ms so that we’re not distracted while waiting on the animation

Let’s look at how we can use CSS transitions.

They animate changes in style rules over a specified duration, so the browser doesn’t have to repaint each frame of animation separately. Like they say: With great power comes great responsibility but luckily for you, this is one superpower you don’t need any training to possess!

You may not know it yet but there are plenty of incredible things that can be achieved with just a few lines of code and some creativity on your part. Let’s start by taking our little kitten here…let me show what I mean by giving him an instant makeover!

CSS Transitions work like magic because they create animations with no more effort than typing a few lines of code.

I’m going to look at the magic that is CSS transitions. Let’s explore!

First, I’m going to explain what a CSS transition is and how you can use them in HTML pages.

One of the great things about these features is that they are animation specific so this means we have complete control over every aspect of it including speed, delay time, duration etc. These animations happen on hover or when an element appears on screen (elements with `opacity: 0`). A quick example would be fading out text as soon as someone mouses off it – neat right?

Now for some code snippets! Below is some sample code using only two different classes :hover/:active . The first

CSS transitions are a really awesome way to animate elements in your application. They can be best described as the following: an animation that occurs when one webpage element changes state or position relative to another page element, usually by fading from one look into another look over time after some trigger event has occurred. CSS transitions make it possible for web developers to create interactive and smooth cross-browser animations without having to resorting to JavaScript libraries like jQuery that only work on modern browsers anyway. The basic syntax of a transition is listed below:

The browser will automatically set up a number of common property types with their corresponding duration values but you’ll have more control if you specify them yourself (see Supported Properties). For example, let’s say we wanted our text
