SVG!

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?

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)
    }
  ...

Make a Responsive SVG Animation Sprite

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

Compare to using text with photos to illustrate an article.

SVG can be styled like text

<svg class="icon" width="24" height="14" alt="Menu">
  <use xlink:href="/svg/sprites.svg#icon-hamburger"></use>
</svg>

<!-- the svg -->
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

    <g fill="#FFF" fill-rule="evenodd"> 
     <!-- I guess this is the part I need to style.. 
          But I have tried everything.. 
          literally, I tried styling * {fill: red} -->

SVG can SNAP

ES6 Template Literals

Previously: String Concatenation

var stringie = "Hi, I ordered " + num1 + " " + 
product1 + "s and " + num2 + " " + product2 + "s.";

Hi, I ordered 5 apples and 2 oranges.

const stringie = `Hi, I ordered ${num1} 
${product1}s and ${num2} ${product2}s.`;

M two points x,y

Q two points for the bezier handle x,y,

two points x,y

function plotter(points, startX) {
  var pathArr = [],
      pathpoints = [];
  for (i = 0; i <= inc; i++) {
    pathpoints.push(points + ((i * (points*2)) + points));
    pathArr.push(` ${startX} ${pathpoints[i]}`);
  }
  return pathArr;
}

rope1.setAttribute("d", `M ${plotter(50, start1)}`.join(" L") );

Plot the points

M xcoord ycoord L xcoord ycoord

SVG can Distort

Distortion Filters

<filter id="turb">
  <feTurbulence id="turbwave" type="fractalNoise" baseFrequency="0" 
    numOctaves="2" result="turbulence_3" data-filterId="3" />
  <feDisplacementMap xChannelSelector="R" yChannelSelector="G" 
    in="SourceGraphic" in2="turbulence_3" scale="40" />
</filter>
function addFilter() {
  var all = document.getElementById("all");
  all.setAttribute("filter", "url(#turb)");
};

(function addFilterTimed() {
  window.setTimeout(addFilter, 5000);
}());

Set the filter on a timer

let turb = document.querySelectorAll('#filter-ripple-2 feImage')[0],
    feD = document.querySelectorAll('#filter-ripple-2 feDisplacementMap')[0];

function sceneOne() {
  var tl = new TimelineMax();

  tl.add('begin');
  ...
  tl.fromTo(feD, 8, {
    attr: {
      scale: 30
    }
  }, {
    attr: {
      scale: 0,
      transformOrigin: '50% 50%'
    }
  }, 'begin+=0.4');
}

Animate the filter

SVG can do on-the-fly logo adjustment

Mavo, by Lea Verou (you should go follow her, and the project)

SVG can increase KPIs

Revisiting old approaches

Responsive animated Infographic

Conversion

(one source example, The Whole Brain Group)

  • increased traffic to their website by over 400%
  • lead increase by almost 4500%
  • the number of new visitors to their site to almost 78%

Problems

  • Not responsive- tipping point: Tim Kadlec
  • Not updated to current context
  • ^ Especially design

All posts older than 2 years.

What Happened?

This pen.

Change the viewbox in JavaScript like we did before:

Responsive:

Responsive:

/* media query example element, mobile first */
@media (max-width: 825px) {
  container {
    width: 100%;
  }
}
@media (min-width: 826px) {
  .container {
    width: 825px;
  }
}

You already know this!

SVG can draw itself

Say you have a shape:

The shape has a stroke that is dashed.

But you make the dash REALLY LONG

The dash's offset is an animatable property!

You can interact with an SVG

  var radius = balloon.getAttribute("r");
  var cySet = balloon.getAttribute("cy");
  balloon.setAttribute('r', parseInt(radius) + 10);
  balloon.setAttribute('cy', parseInt(cySet) - 10);
  if (parseInt(radius) > 125) {
    ion.sound.play("balloon-pop3");
    var balloonTl = new TimelineMax();
    balloonTl.add("pop");
    balloonTl.to("#balloon", 0.05, {
      scale: 5,
      opacity: 0,
      transformOrigin: "50% 50%",
      ease: Circ.easeOut
    }, "pop");
    ...

methods: {
    //this formats the hour info without a library
    getCurrentHour(zone) {
      let newhr = new Date().toLocaleTimeString('en', {
        hour: '2-digit', 
        minute: '2-digit',

SVG can make a GAME

This pen.

How did we use SVG?

Three ways:

  • 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>
        ...
        <HeartMeter score={this.state.score}/>
        ...
      </div>
    )
  }
});
const HeartMeter = React.createClass({
  render() {
    return (
      <div>

  function intersectRect(a, b) {
    return Math.max(a.left, b.left + 40) < Math.min(a.right, b.right - 40) &&

  }

  // can't do if/else because sometimes they both come out at once
  // and one of them will be ignored
  if (intersectRect(tCoords, elCoords)) {
    getHitTestIncrease();
  } 
  if (intersectRect(txCoords, elCoords)) {
    getHitTestDecrease();
  } 
  if (intersectRect(mCoords, elCoords)) {
    getHitTestMargarita();
  }

  requestAnimationFrame(getCoords);
}());

All this, and we didn't even get to data vis!
