Overview of SVG Animation in Web Design
Many designers have knowledge with CSS3 animation, but the topic of SVG animation is slightly unclear. This article gives some tips and resources for designers in creating SVG animations. There are many open source code to help designers in building unique SVG animations. There are many SVG images created for good websites build from scratch.
SVG stands for Scalable Vector Graphics which is a vector file formats have recently came into mainstream web design. SVGs can be scaled to any size and still look crisp because of this feature they are really popular. Retina laptops, Smartphones and desktops all use a wide variety of screen resolutions – but an SVG fit into the screen on all of them.
SVG files can be exported from almost any vector editing program. Adobe Illustrator is the popular at the same time Sketch and Inkscape are two other fantastic tools.
All SVG files are written using XML. This means SVGs can be embedded into a webpage as an SVG file or as raw XML code. The syntax can be a little confusing but the more you play with it the more familiar it’ll become. Take a peek at this introductory post from Tuts+ if you want to learn more about SVGs in web design.
Some of you may be questioning why SVG hasn’t been used up until recently. Web browsers have only just adopted this standard as a serious image format on the web. The compatibility chart from Can I Use SVG clearly demonstrates modern browser support for this image format.
Most of the browser support SVG images and worth in ading to your project work. But Internet Explorer 8 and below are trouble makers in supporting the SVG images. Beyond this they are vector scalability, smaller in filesize and can be created using XML code.
SVG Animation in Websites
If we simplify the idea of an SVG it’s basically just some XML code rendered onto the page as an HTML element. These graphics can be seen as lines, shapes, fills, and other properties of traditional vectors.
The best examples can be found on the Bjango homepage. All the navigation links and the logo are created using SVG images. When you hover any of the links you’ll notice a small elastic bounce effect. The SVG graphics display a hover state on mouseover, and CSS is used to create the bouncing effect.
Most website animation is used for aesthetic purposes. Of course a user experience can be improved through animation but the style should match the website and look ravishing.
The other area where SVG animation can be more effective is with responsive design. Mobile responsive websites stretch to fit any monitor regardless of resolution or screen size. SVG images fit to the resolution with exact same
You should still use pixel-based image formats(JPEG, PNG) when appropriate for photographs, screenshots, or anything which can’t be vectorized. SVGs are best used for dynamic logos/text, icons, or background content.
Two articles worth reading are SVG resolution independence and rethinking responsive SVG both from Smashing Magazine. Not only can SVG images be scaled naturally, but they can also be swapped out with more-detailed or less-detailed versions based on screen resolution.
When it comes to responsive web design & animation there’s no better companion than SVG images.
SVG Animation Tutorials
If you’re eager to learn more about pragmatic SVG animation then take a peek at the following articles. Each one covers a different style of animation which is perfect for those just delving into the subject. Once you get started using vector graphics on the web you’ll be amazed at how much is possible with just a few lines of code.
CSS Tricks may honestly be the best free website for learning modern CSS techniques – and this article is no different. Chris Coyier explains the basics of SVG graphics, how they work on the web, and how to animate them with CSS.
Learn how to export vector graphics from Adobe Illustrator into SVG files for the web. The process might seem complicated but this guide clears up everything from start to finish.
Here’s another tutorial from Tuts+ which explains how you can animate SVG icons using CSS. This tutorial uses christmas light bulbs which light up via CSS3 animation.
If you’re curious about SVG icon animation look no further than MediaLoot’s fantastic guide. It teaches how to export customized SVG icons from Illustrator and then animate them using the CSS3 transform property.
Myself along with many other designers simply adore the content on Codrops. This particular tutorials explains how to customize radio buttons and checkboxes with SVG animation. It’s a powerful technique that pushes the boundaries of modern web development – just what you’d expect from a Codrops article.
Hover animation can rely solely on CSS3 using the :hover pseudo-class. This post explains the process of adding SVG hover animations via CSS to create unique shapes in div elements.
Vector icons can be animated manually or with pre-built code libraries. Snap.svg is a free JS library popular with frontend developers. This tutorial explains how you can incorporate Snap into your website for animating SVG icons from scratch.
Although this post is more of a “beginner” tutorial it does cover a lot of fundamental SVG knowledge. The author Jon McPartland explains how to edit SVG XML code and customize the file for animated effects.
Libraries & Code Snippets
Along with free tutorials I’ve also cataloged a handful of open source code libraries & snippets for SVG animation. Libraries will save time during the development process by reducing the amount of code you need to write. Snippets can be just as helpful offering live examples that you can study from and even duplicate into a project.
The D3 library was mentioned briefly in our JS charting library collection. D3 stands for data-driven documents which can be any type of data display(charts, graphs, tables, etc). The whole library runs on HTML/CSS/SVG for rendering compatible and scalable data in all modern web browsers.
These two arrow icons have been created using pure SVG code as buttons on a webpage. Each arrow lights up on hover and works just like any typical HTML button.
Hover animation is a popular choice with SVG image types. This border effect is attached onto a block of page text which animates a box border on hover.
