To start any animation with AnimeJS you will need a constructor like the following. The targets is the selector for the element s that you would like to target.

How SVG Line Animation Works

Adding duration to your animation will set how long the animation will play. The value for the duration is in milliseconds. You can choose the direction of the animation with the below code. The options for directions you can pick from are normalreversealternate. If you choose not to set a value for direction then normal is the default direction. You can also add easing to your animation. There are a bunch of different values to set for easing that can be found at animejs. My favorite value is easeInOutSine because it performs like ease-in-out from CSS animations and works well for me on just about every animation I create.

In my opinion, staggering is the coolest feature because it allows you to set one animation after or during another, meaning you can make nice wave effects with your animations. The documentation for staggering can be found at animejs.

If you have several elements selected for an animation then the code below sets a millisecond delay between each elements' starting animation. To set a normal delay you will set the delay value to your delay in milliseconds like below. Instead of this code setting a delay between each element, this sets the delay for the entire animation. This example, when called, will wait ms then start animating.

To add a transform to your animation it's just like CSS transforms but you can skip the transform and go straight to translate, rotate, or skewing. What I mean by this is that in CSS you would set a translate of -1rem on the x-axis like transform: translateX -1rem ; and with AnimeJS you would do the same like this example. You can add as many values as you would like in the arrays. If you want to make an SVG that draws itself from nothing then you will like this feature. To add line drawing you will need an element like the path in the SVG because it works with stroke-dasharray and stroke-dashoffset.

If you want an SVG to transform into a different shape then this is the feature for you! You can add morphing to any SVG element with a path set like the d attribute in the path element.

In the below example you can change the d for whatever sets the elements path, for example with the polygon element you would change it to points. Below is another Codepen example of both morphing and drawing although a bit of a messy animation it gets the point across.

You can force elements to be paths though. I have a Lodge video on this. You may need to resort to trickery like adding an additional vector point along an already straight edge. The 0. Sarah comprehensively covers the possibilty of animation, the tools, and does it all in a very practical way. The dashed-line stroke technique is very clever, looking forward to playing around with it.

Just tried it in safari 8. Gotta scroll in the window using a mouse wheel or something. This is great. I tried adding it on my website but it seems not to work in IE8 and Safari. Any suggestions?

I would like to animate a dashed line in a SVG-file. All the methods I found are not suitable for me. Of course, this is not working, when I want the line to be dashed. Is there anybody who has an idea how to solve this? PS: I can't use two paths over each other to hide the path underneath because I'm having a coloured background.

One of the ways to do this is with Javascript. It duplicates a path by creating a polyline. Try the example below:. But note I think you should just be able to add stroke-dasharray to your animation and lower the dash array in your css.

But how can I loop through the function to animate all paths myPath1, myPath2, …? Rather than loop, the simplest way for this application would be to merely repeat each function for each path. Worked perfectly!

I like the idea with creating a polyline and checking points by getPointAtLength — really nice. But the OOP is really poor here, why repeating same code for each city and not use one common function for this? You can also do this just using masks as so:.

How well do you know CSS selectors? In the example above your task is to decide whether the selector targets exactly the highlighted element. Hope Armstrong, a product designer at Treehouse, has written an article demonstrating why the simple combination of SVG and CSS is appealing and how to make these lightweight, scalable animations!

There are various CodePens, including the melting popsicle above, which Hope animated by changing the position of the drops using transform: translate. To make them disappear, she animated the opacity. Zach Saucier walks us through creating a neat blob reveal animation with SVG and clip-path. To make the colours change for every new set of words as in the example above, Zach used JavaScript and moved the CSS animation that was hiding the text lines to the JavaScript.

See the Pen Color this sofa! Take the PNG of an object, save it as a specific size, draw an SVG vector around the section you want to colour change, photoshop this section of the PNG white, and keep the blank space.

It looks to me as though its a 1px div with a white background that has its position and height adjusted dynamically via js to match the scroll position while inside a 50vh parent container. If we colour the outer container red you can see how the white line is animated from outside the red box overflow:hidden hides the white line until it meets the bottom of the red box and then continues until it disappears through the bottom of the red box.

The basics of what you need are a container that is 50 vh tall with overflow:hidden. You start with the white line transformed out the top of the container so it is invisible. Obviously vice versa when you scroll up. If I get a chance later I will set up the css for the boxes and then you can investigate adding js on scroll etc. I have a question, though. This may be dumb but when the white line is out of the container and the user keeps on scrolling, where does the white line go?

Does it keep on moving down as the user scrolls down? Thank you so much, PaulOB. If you look in dev tools it seems that the line just keeps getting animated with the scroll position.

As the red container comes back into the viewport then so will the white line as it is constantly animated in line with the scroll position. I suppose the line could have been stopped animating once it was outside the red box but then I guess you have to re-check when it has re-entered that area.

Have to rush out soon but hopefully you can make a start. Thank you so much for this. Take care! The code is all in the page so just view source. I;m sure it could be tidied up a bit to look better. I am definitely out the door now. This is great! Thank you so much. You are so cool. I added a small fade in effect for the blocks using in-view. Hi, PaulOB! You are helping me a lot.

Not really sure why. The white line behaves the same changes length and moves in both.Learn more and introduce yourself. Article Categories: CodeFront-end Engineering. As we saw in Part 1CSS is the way to go for simple animations that can be defined ahead of time. Typically, the first reason will involve some CSS animations and the second will involve third-party Javascript libraries like jQuery. From a frontend perspective, Javascript is most useful for listening to user interaction — things like clicks, scrolls, and keypresses.

Often times, we want an element to animate in response to one of these events.

Beginner’s Guide to Web Animation: Part 2, Javascript & SVG

There are many different types of UI animation, but in general, you can think of them as falling into two categories:. Why does a defined end state sound familiar? This is the part where CSS and Javascript collide. On click of the hamburger button, we want the menu to slide in from the right. First, we need to define the starting state and end state in CSS:. You can see the end state is defined by the class.

There are many benefits to this approach. First, your code is cleanly separated by allowing Javascript to handle state and CSS to handle animation. Another classic example of this technique is the sticky navigation bar.

I recently implemented this on pogo. Again, I use Javascript to monitor user scrolls and change classes based on their direction. Take the example of a page read indicator — a progress bar that shows how far along you are on a page.

There is no way to know ahead of time what the width of. Thus, there is no fixed value that we can define as an end state in CSS. Instead, we need to use Javascript to directly change the width as needed. Each time a user scrolls, Javascript grabs the new scroll position and calculates progress made against the full height of the article. In Javascript, there are two ways to directly set a style:. This technique can make really engaging effects like pages animating on scroll or realistic motion hovers.

It can lead to stuttering and stilted animation. These animations require you to chain multiple sequences in a row e. At best, libraries allow you to create complicated animations and get consistent, cross-browser results without much fuss or hassle. At worst, they add unnecessary bloat and slow down your site — jQuery alone will add 87kb of extra code!

Again, try to get as far as you can with CSS and vanilla Javascript before turning to a hefty library. One such technique is called SVG line animationwhich gives the neat effect of an image drawing itself. In the CSS, you can see that we set up the starting and end states on hover of path.

We then add a CSS transition to achieve the final effect, drawing the line using stroke-dashoffset and fill ing in the heart with a slight delay of 0. This technique can be put to all sorts of uses like button hoversanimating logosand even text outlines. Furthermore, browser support is still spotty, especially for Internet Explorer.

They also help smooth out browser inconsistencies and optimize for good performance, making it well worth the overhead. Nobody likes popups, so we waited until now to recommend our newsletter, a curated periodical featuring thoughts, opinions, and tools for building a better digital world.
