![]() As our animation description is algorithmic as well, the loading animation can be easily reproduced when the details of the logo are changed. ![]() In order to achieve our goal of animating the logo directly, we need a way to animate the SVG vector art. In former times, people would not have used SVG for that purpose, but rather some plugin-based technology like the proprietary Adobe Flash.Īs of 2020, it is possible to create vector animations for the web using web native technology. Unfortunately, there is more than one canonical way to do it. SMIL was originally intended by W3C to become the main animation method for SVG, but according to SVG working group’s github issues this is a point of debate. With the last changes in CSS Specifications, CSS got more powerful in terms of animating elements on a web page. CSS Animations Level 1 gives the CSS author more control over the animation details than CSS Transitions.CSS Transitions is used for animating between CSS property changes.Since the CSS standard was modularized, the available bits and pieces live in different specification modules. Web Animations focuses more on the timing and interaction between a web page and an animation.It provides a language to describe complete animations of CSS properties. It is more general and agnostic of the concrete SVG animation technology used.Īll CSS Animation standards focus on animation of CSS properties only. This is logical, as the whole idea behind CSS is the separation of concerns between content and presentation. In practise, this limits CSS animations to SVG presentation attributes. This is the subset of SVG element attributes, that are exposed as CSS properties. JavascriptĪnother approach for animating SVG vector graphics is using the browser’s JavaScript Engine to manipulate the SVG DOM. In particular this becomes simpler when using a reactive JavaScript framework and modeling time as events. ![]() If you do not want to use vanilla JavaScript a.k.a. modern days assembly language, you can resort to more convenient transpiled languages like Elm or ClojureScript + re-frame. Maybe you can achieve the same using the WebAssembly compilation features of other languages. For example Go supports WebAssembly as compilation target. However, I am not sure how far you get when it comes to SVG DOM manipulation. There, animation will not be limited to time as event source, but will have to react to other events like button presses, mouse movement or even network interaction with other players. In this case using a full-fledged language is really natural. When it comes to simple time-based animations, it feels like overkill and less declarative than e.g. The SVG 1.1 Standard includes some animation properties itself, hinting to SMIL and SMIL Animation as the standard way of describing SVG animations. ![]() SVG serves as a host language for SMIL in that case. This is the approach I will take in this article. I will first explore all bits and pieces you need to create our animation. In the end you will put them together to a complete and working animation. So for example if you want a circle to move from the left to the right, you can write SVG animations work by describing the temporal behaviour of our elements’ attributes. Neat! You see how the attribute cx changes over the duration of 3 seconds from cx="50" to cx="350". The end="click" helps you stop the animation while reading this article.
