SVG!

This pen I made

SVG!

• Crisp on any display
• Less HTTP requests to handle
• Easily scalable for responsive
• Small filesize if you design for performance
• Easy to animate
• Easy to make accessible
• Fun!

SVG!

Positioning in CSS got you down?

This pen by Chris Coyier

We can do stuff like this, All fully responsive in every direction

This pen made with Sara Soueidan's circulus.

SVG can mean conserving space in your UI until icons are needed

It doesn't neccessarily have to be fully fluid, either. Let's Implement some Responsive Design.

Like legos.

This pen.

//variable declaration for the global repeated animations
const gear = $("#gear1, #gear2, #gear3");
...

//animation that's repeated for all of the sections
function revolve() {
  let tl = new TimelineMax();

  tl.add("begin");
  tl.to(gear, 4, {
      transformOrigin: "50% 50%",
      rotation: 360,
      ease: Linear.easeNone
    }, "begin");
    ...

  return tl;
}

const repeat = new TimelineMax({repeat:-1});
repeat.add(revolve());

function paintPanda() {
  let tl = new TimelineMax();

  tl.to(lh, 1, {
    scaleY: 1.2,
    rotation: -5,
    transformOrigin: "50% 0",
    ease: Circ.easeOut
  }, "paintIt+=1");
  ...

  return tl;
}

//create a timeline but initially pause it so that we can control it via click
const triggerPaint = new TimelineMax({ paused: true });
triggerPaint.add(paintPanda());

//this button kicks off the panda painting timeline
button.addEventListener("click", function() {
  triggerPaint.restart();
});

...

We can use this stability for Page Transitions

In React

  toggleShape() {
    if (this.state.screen === 0) {
      this.animFire(this.state.splitText)
    } ...
    this.setState({
      screen: (this.state.screen + 1) % 3
    })
  }

  animFire(splitText) {
    const tl = new TimelineMax,
          stA = 'start';
    
    TweenMax.set([this.g1.childNodes, this.g2.childNodes], {
      clearProps:'svgOrigin'
    })

    tl.add('start')
    tl.staggerFromTo(this.g1.childNodes, dur, {
      drawSVG: '68% 100%'
    }, {
      drawSVG: '27.75% 0%',
      ease: Back.easeOut
    }, stD, stA)
    ...
  }

In Vue.js with Nuxt

JS Hooks

export default {
  transition: {
    mode: 'out-in',
    css: false,
    enter (el, done) {

      let tl = new TimelineMax({ onComplete: done }),
          spt = new SplitText('h1', {type: 'chars' }), 
          chars = spt.chars;

      TweenMax.set(chars, {
        transformPerspective: 600,
        perspective: 300,
        transformStyle: 'preserve-3d'
      })

      tl.add('start')
      tl.from(el, 0.8, {
        scale: 0.9,
        transformOrigin: '50% 50%',
        ease: Sine.easeOut
      }, 'start')
      ...
      tl.timeScale(1.5)
    }
  ...

Viewbox Shift with a Sprite

This pen.

ViewBox Shift with JavaScript

var shape = document.getElementById("shape");

// media query event handler
if (matchMedia) {
  var mq = window.matchMedia("(min-width: 500px)");
  mq.addListener(WidthChange);
  WidthChange(mq);
}
// media query change
function WidthChange(mq) {
  if (mq.matches) {
    shape.setAttribute("viewBox", "0 0 490 474");
  } else {
    shape.setAttribute("viewBox", "0 490 500 500");
  }
};

Acts like a window to show and hide the requisite parts of the sprite

SVG can make a GAME

This pen.

How did we use SVG?

• Directly inline in the HTML, for loops
• Background images, for things like taco
• Inline in React

const App = React.createClass({
  getInitialState: function() {
    return {
      score: 500,
      startTime: 0,
      finalScore: 0
    };
  },
  
  _startGame: function(setGameToStart) {
    this.setState({ isPlaying: setGameToStart,
                    score: 500,
                    startTime: Date.now() 
                  });
  },
  
  _updateScore: function(scoreDelta) {    
    let score = Math.min(Math.max(0, this.state.score + scoreDelta), 1270);
    this.setState({ score: score });
    if (score === 0 || score === 1270) {
      this.setState({ isPlaying: false,
                      finalScore: 10000 - Math.round((Date.now() - this.state.startTime) / 30) });
    }
  },
  ...
  
  render() {
    return (
      <div>
