Styling SVG with CSS: Capabilities and Limitations


  

SVG is the new standard for vector images in the browser. Vector editors such as Adobe Illustrator allow to directly save to that format and modern browsers have no problems to properly display SVG. As SVG graphics consist of markup, they can be created and maintained using your favorite text editor, just as you do with your HTML. It is even possible to style SVG with CSS, though you’ll need to know about quite a few differences in doing so, compared to styling HTML.

SVG and JavaScript: What Is Possible, What To Consider?


  

SVG has been around for quite some time now, waiting. Waiting for proper browser support. The wait is now over as all modern browsers support the format today. With Flash being on the decline, SVG has grown even more popular. Just like the proprietary Flash format, SVG is vector-based and can even contain animations. You need not even miss out on scripting, as SVG supports JavaScript right inside its own format. Think of an open ActionScript, only more commonly known.

HTML 5 and SVG: Providing a PNG Fallback with PHP and ImageMagick


  

Using SVG in web design has many advantages. Being a vector format is the biggest and has it standing out from the crowd of other image formats. You could have guessed, though, that while modern browsers do already support SVG, the good ole Internet Exploder doesn’t, at least not below version 9. As older versions of Internet Explorer are still out there in the wild, you should always consider implementing a fallback solution. Using PHP and ImageMagick makes it a snap to provide a fallback to PNG..

Surviving the Zombie Apocalypse with HTML5 and SVG #2: Text, Paths and Basic Animation


  
zombie-apocalypse-2

The first article in this series covered the basics of SVG, an overlooked, underappreciated aspect of HTML5. While different browsers implement SVG in different ways, the previous walkthrough described how to create text, incorporate SVG images and build basic shapes such as circles, polygons and paths in a way that all browsers recognize.

Typicons: Free Icon Font with 88 Symbols


  

Stephen Hutchings from Australia undoubtedly brought forward an intelligent new term when he called his icon font Typicons. Nevertheless, Typicons are just that, an icon font, but a good one with 88 pieces. Typicons are especially useful in app-design as most of the symbols relate to user interface aspects typically needed for controlling functionality. I guess, Hutchings had development for mobile clients in mind when he created the symbols.

Typicons: only a few examples

Typicons: a grid of 24 square pixel, but scalable to any size

Even though they have their downsides, web design without icons is unthinkable these days. Several methods of icon usage have been established. At first, icons were implemented via separate files, which led to separate http-requests for every single file. For reasons of performance optimization, modern websites should try to invoke only as many requests as absolutely unavoidable. Separate icon files have proven not to be the right method. Next came and still stay the so-called sprites. Here we have only one file which includes all the icons needed. To display a certain symbol, we use CSS to locate only a part of the whole file and show this sprite to the user. This method is established, but has its downsides too. If you’d want to serve different devices and/or different resolutions, you’d have to provide different sprite-files, which certainly means a higher effort in producing them. These would have to be targeted using media queries, which you’ll not always want to use.

Freely scalable icon fonts are the cure to these pains. You don’t need to worry about their resolution even on the new iPad, the new MacBook Pro or other HiDPI-screens. That’s where Typicons come in.

The download weighs in at 1,6 MB and contains the necessary font files (EOT, SVG, TTF, WOFF) as well as the corresponding CSS for easy implementation into your own website. On top of this, Hutchings provides you with vector files in the formats of Adobe Illustrator and EPS (encapsulated Postscript), thus leaving nothing to be desired. Experienced designers can take and modify the icon set to open up new use cases.

Typicons are shared under a Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) license. That means they can be used free of charge for personal as well as commercial projects. You must attribute the work in the projects you use it, typically by providing a backlink. If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to the one, Hutchings shares it under. Fair enough…

Cool SVG Puzzle Demo Using JQuery SVG

Via HRJ ("Overworked mad genius readying to take on the world. I am his neighbor") comes a cool puzzle piece demo written using SVG and JQuery SVG:

HRJ has some nice code. First he calls the Flickr API using JQuery and JSON and makes a JigSaw puzzle piece for each one; in the code below he is also grabbing a picture name from the #hash value in the URL if it is present:

JAVASCRIPT:
updateStatus('Fetching photo from Flickr');
$.getJSON('http://api.flickr.com/services/rest/?method=flickr.photos.getInfo&api_key=3cac122425cd16eaa1ea4c1b8bb3ff26&photo_id='+specifiedHash[1]+'&format=json&jsoncallback=?', function(response) {
    if (response.stat && response.stat == 'ok') {
      var p = response.photo;
      $.getJSON('http://api.flickr.com/services/rest/?method=flickr.photos.getSizes&api_key=3cac122425cd16eaa1ea4c1b8bb3ff26&photo_id='+specifiedHash[1]+'&format=json&jsoncallback=?', function(response2) {
        if (response2.stat && response2.stat == 'ok') {
          updateStatus('Observe the tiles. Click on them to begin.');
          var medSize = response2.sizes.size[4] ? response2.sizes.size[4] : response2.sizes.size[3];
          currJigsaw = new JigSaw(medSize.source, medSize.width, medSize.height, p.urls.url[0]._content, p.title._content);
          var locationMatch = photoHashIgnorePattern.exec(window.location),
              myLocation = locationMatch ? locationMatch[1] : window.location;

          $('#puzzleLink').html('<a href="'+myLocation+'#photo_'+p.id+'">Puzzle\'s link</a>');
        }
      });
    } else {
      updateStatus('Error! Couldn\'t load image');
    }
});
 

The code that animates all the tiles when you first click on a board is interesting, using a bit of JQuery SVG:

JAVASCRIPT:
function startPlayInit() {
      var imgCenter = {x : width/2, y: height/2};
      for (var i = tiles.length; i--;) {
        $(tiles[i].sN).animate({'svgTransform':'rotate('+[tiles[i].r,imgCenter.x, imgCenter.y].join(',')+') translate('+[imgCenter.x, imgCenter.y].join(',')+')'}, {
          duration:1000,
          complete : startPlay
        });
      }
    }
 

Basically each of the tiles is rotated and translated over 1 second with a nice animation effect.

Adobe Announces HTML5/CSS3/SVG Pack for Illustrator

Exciting news from Adobe; they’ve announced a new HTML5 Pack on Adobe Labs with support for HTML5, CSS3, and SVG:

Adobe is pleased to announce the availability of the Adobe® Illustrator® CS5 HTML5 Pack. This add-on for Illustrator CS5 15.0.1 provides initial support for HTML5 and CSS3, extends SVG capability in Illustrator CS5, and helps you easily design web and device content. In combination with the HTML5 features available in the Adobe Dreamweaver CS5 11.0.3 updater, these new tools allow web designers to take advantage of the latest advancements in HTML5.

While HTML5 and CSS3 will not be finalized for some time, and SVG support in browsers will continue to evolve, the extension provides support for a set of currently implemented features.

Some of the benefits of the HTML5 Pack:

  • Efficiently design for web and devices by exporting Illustrator Artboards for unique screen sizes using SVG and CSS3 media queries.
  • Create web widgets with Illustrator by generating dynamic vector art for data driven web work-flows.
  • Take advantage of the latest enhancements to SVG and Canvas to generate interactive web content.
  • Map artwork appearance attributes from designer to developer tools—export from the Illustrator Appearance Panel to CSS3 for streamlined styling of web pages.

Greg Rewis discusses it more in the video below:

Mordy Golding has a good description of some of the new features in this lab pack:

Parameterized SVG

You can designate certain attributes (i.e., fill, stroke, opacity) as variables right from the Appearance panel in Illustrator. When saved as SVG, developers can easily change the variable definition to “reskin” or modify the art. You can even create global variables.

Multi-screen SVG

You can create multiple artboards in Illustrator at various sizes, for example to design art for different screen sizes. You might do this to create different designs for mobile, tablet, and desktop versions of a design for example. You can then save your file as SVG and include all the different artboards. Illustrator creates an HTML file and a CSS file, along with separate SVG files for each artboard. The CSS uses media queries to detect the screen size and automatically serves up the correct SVG image.

Mark objects as canvas in SVG

You can select an object on the Illustrator artboard and then choose Object > HTML5 Canvas > Make. These elements are rasterized and included as canvas elements when saved as SVG, giving developers the ability to control the elements via JavaScript.

Export named character styles as CSS

You can define character styles in your Illustrator document, and then export those character styles as a valid CSS file. You can do this directly from the Character Styles panel.

Export artwork appearances as CSS

You can select an object in Illustrator and export valid CSS directly from the Appearance panel. Of course, if you mockup an entire page in Illustrator, you can simply select all of it and export it to a single CSS file. IDs are picked up from the Layers panel (so you want to name artwork carefully), and Illustrator can export Fill, Stroke, Opacity, and Absolute Position and Dimensions.

Include selected Graphic Styles as CSS in SVG

You can select styles from the Graphic Styles panel and choose to have them exported when you save your file as SVG. What’s really cool is that you can include styles even if they aren’t applied to your artwork. This would allow you to deliver multiple styles to a developer within a single SVG, and even programmatically swap styles.

Great work Adobe!

Raphaël 1.5 Released


Dmitry Baranovskiy and team have released another version of Raphaël, an excellent drawing and animation library backed by SVG (VML on Internet Explorer). New features in Raphaël 1.5 include custom attributes and keyframes. Keyframes can be defined similar to CSS3 Animations:

JAVASCRIPT:
el.animate({
    "20%": {cy: 200, easing: ">"},
    "40%": {cy: 100},
    "60%": {cy: 200},
    "80%": {cy: 300, callback: function () {}},
    "100%": {cy: 200}
}, 5000);
 

Check out a demo of the new keyframe animation.

Custom attributes is also a new feature that makes it easier to do things like animating a portion of an attribute segment (demo).

Full release notes:

  • fixed IE8 issue with the HTML element named Raphael
  • fixed precision for arcs in IE
  • added caching to getPointAtSegmentLength function
  • added ability to do more than one animation of an element at the same time
  • added "cubic-bezier()" as an easing method
  • added new syntax for animation (keyframes)
  • hsl2rgb now accept h as degree (0..360), s and b as % (0..100)
  • show="new" instead of target="blank" for SVG
  • added angle method
  • added snapTo method
  • cached popup || activeX for IE
  • fixed insertAfter
  • fixed timeouts for animation
  • added customAttributes

BTW I just noticed that Dmitry is now at Sencha; they're assembling quite the team! Congrats Dmitry!

CanVG: Using Canvas to render SVG files

We love to recursively implement one technology on top of another. We have had Canvas support added to IE via VML, Flash, and Silverlight. We have had SVG implemented in Flash. Flash implemented in SVG.

The latest experiment is from Gabe Lerner and is CanVG. As you can guess, it renders SVG files via the <canvas> element. All in a few hundred lines of code!.

Check out the test playground to see it in action.

Microsoft joins SVG Working Group

My gut feeling whenever I hear a “we are joining a group” type post from anyone is “thanks for telling us, ping me when you have an implementation”.

However, when someone as big as Microsoft blogs about joining the W3C SVG Working Group they are trying to send a signal. Hopefully they will help the process and SVG will proceed nicely and we will see it on more user agents.

But, as a friend just said, I will hold my breath to celebrate until I see it and Canvas in a browser :)

In fact, the lack of talk about Canvas from Microsoft has me worried.
