June 13, 6 min read If not used correctly, scroll-linked animations suffer from lower frame rates and apparent jitter due to inefficiencies in implementation. Even the hot topicthe parallax scrolling effect, met its fair share of inefficiencies.
Animations are not always to blame, because even sans effects or improper scroll event listeners still create headaches. Twitter responded to a rash of issues with laggy scrolling inleading the creator of jQuery John Resig to conclude expensive scroll event handlers are a bad idea.
Scroll-linked animations are often based on scroll position. For such applications, scroll event listeners are polling for scroll position — if scroll position is within range of a target, perform a scroll-linked animation. Analogously, scroll-linked animations would listen for scroll position rather than check scroll position. The observer pattern, specifically IntersectionObserver is a durable technique that accomplishes just this.
Roughly speaking, once a certain scroll position has been reached, the IntersectionObserver event handler is executed. We describe in more detail and more precisely what it accomplishes below. Whenever that element, known as the targetappears on the screen, the Intersection Observer callback is invoked.

There are three configuration options to note:. The following is a sample intersection observer configuration. Anytime the sample box is fully visible in the user viewport, the handler is triggered:.
View the codepen hereand try scrolling the black box fully into view and then partially or completely out of view.
Whenever the box is fully scrolled into view, the console reads Fully visible! However, this does not encompass scroll-linked animations that occur continuously, as the user scrolls. One example is a parallax effect. Several workarounds exist if a scroll event handler is necessitated, in these scenarios.
Using CSS animations
These methods generalize to all high-frequency event handlers and focus on reducing the number of times a handler is invoked.
The former is called trailing mode.When you specify CSS styles inside the keyframes rule, the animation will gradually change from the current style to the new style at certain times. Note: The animation-duration property defines how long time an animation should take to complete. If the animation-duration property is not specified, no animation will occur, because the default value is 0s 0 seconds.
It is also possible to use percent. By using percent, you can add as many style changes as you like. The animation-delay property specifies a delay for the start of an animation. Negative values are also allowed. If using negative values, the animation will start as if it had already been playing for N seconds.
In the following example, the animation will start as if it had already been playing for 2 seconds:. The animation-iteration-count property specifies the number of times an animation should run. The following example uses the value "infinite" to make the animation continue for ever:.
The animation-direction property specifies whether an animation should be played forwards, backwards or in alternate cycles. The following example uses the value "alternate" to make the animation run forwards first, then backwards:. The following example uses the value "alternate-reverse" to make the animation run backwards first, then forwards:. The animation-timing-function property specifies the speed curve of the animation.
CSS animations do not affect an element before the first keyframe is played or after the last keyframe is played. The animation-fill-mode property can override this behavior. The animation-fill-mode property specifies a style for the target element when the animation is not playing before it starts, after it ends, or both. The same animation effect as above can be achieved by using the shorthand animation property:.

What is Failure Art? The LOGO of the jitter we are familiar with is just one form of failure art. It has a magical feeling, looks like it flickers, vibrates and is eye-catching. Fault Art It simulates the sensation that a faulty picture signal causes an imaging error. This failure is due to the inability of the cyan and red color blocks to coincide.
From the era of film to today's digital age, this failure has been a familiar phenomenon to the audience. I saw it last month CSS Failure Art This article, recently trying to change your mood, began copying its animation by the way, hanging the UWP section of the blog park.
Under the Microsoft. Effects namespace BlendEffect Used to combine two pictures Background and Foreground as input sourceswhich contain multiple modes, as shown in the following image:. I am Using Win2D to Realize Pierced Text There are instructions on how to use Win2D to create a CompositionSurfaceBrush that contains text, this time re-encapsulating it, and then using the code below to show the mixing effect in various modes.
Now that you understand the use and function of BlendEffect, you can try some fault art. Take this picture to try:. Use the code above to mix this picture with CompositionColorBrush created from Colors. Red0, 0 and Colors. Cyan 0,using BlendEffectMode. Lighten to get the following results:.
Darken mixes two pictures and offsets one of them by 10 pixels to achieve the following effect, so that the breakdown art of the picture is completed:.
Continue copying the animation, even with the title. Lighten and animate their Offset:. Put another black line moving up and down in the middle, and the effect of the failure comes out:. Multiply mixes several pixels apart to create a more complex fault art animation:.
Then put a white text after it, adjust the height of the first two words respectively, as follows:. I specially created a new one to copy animations from the big guys project.
There are still a lot of animations to refer to in the original text, but I gave up halfway and got to know the general principle and the freshness went away. My blog has also written, my pictures have been truncated, and I will throw them away if I get bored. Programmer Group A programming skills sharing group.

You can prevent the children from being stretched and skewed during the animation by counter-scaling them. The immediate problem with this approach is that it requires animating width and height. These properties require calculating layout, and paint the results on every frame of the animation, which can be very expensive, and will typically cause you to miss out on 60fps.
An alternative to animating width and height might be to use the now-deprecated clip property to animate the expand and collapse effect. Or, if you prefer, you could use clip-path instead. Using clip-pathhowever, is less well supported than clip. But clip is deprecated. While better than animating the width and height of the menu element, the downside of this approach is that it still triggers paint.
Since this effect involves something getting bigger and smaller, you can use a scale transform. The downside to this approach, like most things in rendering performance, is that it requires a bit of setting up. If you need to do that, however, be cautious: getBoundingClientRect or offsetWidth and offsetHeight forces the browser to run styles and layout passes if styles have changed since they were last run. In the case of something like a menu, we can make the reasonable assumption that it will start out being in its natural scale 1, 1.
This natural scale represents its expanded state, meaning you will need to animate from a scaled down version which was calculated above back up to that natural scale. But wait! Well, as you can see below, yes. So what can you do about this? There are two things to notice about that:. The counter-transform is also a scale operation. This is good because it can also be accelerated, just like the animation on the container.
You may need to ensure that the elements being animated get their own compositor layer enabling the GPU to help outand for that you can add will-change: transform to the element or, if you need to support older browsers, backface-visiblity: hidden.
After all, you could then use an easing equation to calculate the scale and counter-scale values per frame.Learn Development at Frontend Masters. The animation property in CSS can be used to animate many other CSS properties such as colorbackground-colorheightor width. Each animation needs to be defined with the keyframes at-rule which is then called with the animation property, like so:.
Each keyframes at-rule defines what should happen at specific moments during the animation. These keyframes can then be controlled either by the shorthand animation property, or its eight sub-properties, to give more control over how those keyframes should be manipulated.
You can comma-separate the values to declare multiple animations on a selector as well. In the example below, we want to change the color of the circle in a keyframe whilst also nudging it from side to side with another. Animating most properties is a performance concernso we should proceed with caution before animating any property. However, there are certain combinations that can be animated safely:.
Animatable properties tend to colors and numbers. An example a non-animatable property is background-image. This browser support data is from Caniusewhich has more detail. A number indicates that browser supports the feature at that version and up. Although browser support is quite good for this property in modern browsers, we might want to support as many older browsers as we can.
Frontend Masters is the best place to get it. Maybe this calls for an update? Also, using the -webkit- prefix in your examples could possibly promote the bad practice of using -webkit- only. Maybe such examples need to be changed to the prefix-free version instead?
I did know that, this was way out of date that way pre me knowing that I guess. Got it fixed up. Is this possible??? Please help.
