jQuery setTimeOut method / Coffee, coffee more coffee…

The setTimeout() method is JavaScript function however, this function can be also used with a library such as jQuery.

The setTimeout() method calls a function or evaluates an expression after a specified number of milliseconds. The function is only executed once.

Note: 1000 ms = 1 second

Syntax:

setTimeout(function() {
      // Do something after 1 second
      // the function takes time in a millisecond – and hence we have specified ‘1000’ as the timeout value
     }, 1000);

To create the animation below I used setTimeOut method:

What do you need to do?

  1. Add HTML
  2. Add CSS
  3. Add jQuery

Step1.

Add HTML

Create the circle, and add the content (mug, coffee, drip and the fill).

<div id="circle">
   <div id="content">
     <div class="mug">
       <div class="handle"></div>
       <div class="inside">
         <div class="coffee"></div>
       </div>
       <div class="drink"></div>
       <div class="drip"></div>
        <div class="drip1"></div>
        <div class="drip2"></div>
     </div>
     <div class="fill"></div>
  </div>
</div>

Step2.

Add CSS

Set the colour and position of the background, circle and the content:

body{
   background-color: #e26d5c;
   background-size: 100vh;
   display: flex;
   justify-content: center;
   align-items: center;
}
#circle {
   background-color: #A1C181;
   width:450px;
   height:450px;
   top:30px;
   border-radius: 50%;
   position: relative;
   z-index: 1;
   overflow:hidden;
}
#content{
   background-color:transparent;
   width:450px;
   height:450px;
   border-radius:50%;
   position:relative;
   box-shadow:inset 5px -5px 0 rgba(0,0,0,0.07);
}

Style the mug:

.mug {
  position: absolute;
  width: 170px;
  height: 180px;
  background-color: #FCCA46;
  top: 135px;
  left:140px;  
}

.mug:after {
  position: absolute;
  content:"";
  width: 170px;
  height: 40px;
  border-radius:50%;
  background-color: #FCCA46;
  top:-18px;
}

.mug:before {
  position: absolute;
  content:"";
  width: 170px;
  height: 40px;
  border-radius:50%;
  background-color: #FCCA46;
  top:158px;
  box-shadow: 1px 25px 3px rgba(0,0,0,0.09);
}
.handle {
  position: absolute;
  border: 17px solid #FCCA46;
  border-radius:50%;
  width: 100px;
  height: 100px;
  left: 100px;
  top: 25px;  
}

.inside {
  position: absolute;
  content:"";
  width: 155px;
  height: 40px;
  border-radius:50%;
  background-color: #ffe066;
  top:-13px;
  left: 7px;
  z-index:1;
  overflow: hidden; 
}
Coffee jQuery

Add Coffee and drip:

.coffee {
  position: absolute;
  width: 200px;
  left:-20px;
  height: 40px;
  border-radius:50%;
  background-color: #432818;
  top:30px;
  opacity:1;
  
}

.drip {
  position: absolute; 
  width: 5px;
  height: 5px;
  background-color: #432818;
  z-index:2;
  left:60px;
  top:20px;
  opacity:1;
  
}

.drip1 {
  position: absolute; 
  width: 8px;
  height: 2px;
  left:35px;
  top:20px;
  background-color: #432818;
}

.drip2 {
  position: absolute; 
  width: 8px;
  height: 2px;
  left:130px;
  top:20px;
  background-color: #432818;
}

.fill {
  position: absolute;
  width: 500px;
  height: 500px;
  top:450px;
  background-color: #432818;
  z-index:3;
}

.drink {
  position: absolute;
  width: 20px;
  height: 2px;
  background-color: #432818;
  top:-150px;
  left: 75px;
  z-index:2;
}

Step3.

Add jQuery

setTimeout(function(){
    $(".drink").animate({
        "height": "+=275",
        top: "-=100"
    })
}, 2500, "ease")


setTimeout(function(){
    $(".coffee").animate({
        "height": "+=300",
        top: "-=100"
    })
}, 3000, "ease")

setTimeout(function(){
    $(".drip").animate({
        "height": "+=300",
        bottom: "-=100"
    })
}, 4500, "ease")

setTimeout(function(){
    $(".drip1").animate({
        "height": "+=300",
        bottom: "-=100"
    })
}, 5500, "ease")

setTimeout(function(){
    $(".drip2").animate({
        "height": "+=300",
        bottom: "-=100"
    })
}, 6500, "ease")

setTimeout(function(){
    $(".fill").animate({
        "height": "+=500",
        top: "-=500"
    }, 5000)
}, 5500, "ease")

            stroke-dashoffset: 1650;
            }
          75% {
            stroke-dashoffset: 0;
            fill-opacity: 0;
          }
          95% {
            stroke-dashoffset: 0;
          }
          100% {
            fill-opacity: 1;

Sketchborad JavaScript

sketch board javascript

Do you like sketching? Did you know that you can sketch on Java Script canvas too?

*animation opened in the Safari browser.
To see the live output of the animation click here.

What do you need to do?

To create the JavaScript sketch board you need to have the pencil cursor in .png/ SVG format (for practising you can use mine below) and follow the steps below:

  1. Add HTML
  2. Add CSS
  3. Add JavaScript/ jQuery

Step1.

Add HTML

Create the canvas-wrap, add canvas and buttons.

<div id="canvas-wrap">
  <div class="sketch-board">
    <div class="paper"></div>
  </div>
  <div class="paperclip"></div>
<canvas id="canvas"></canvas>
<button class="button" id="clear">Clear</button>
<button class="button" id="undo">Undo</button>
<button class="button" id="brushBlack">Black</button>
<button class="button" id="brushYellow">Yellow</button>
<button class="button" id="brushRed">Red</button>
<button class="button" id="brushBlue">Blue</button>
<button class="button" id="brushGreen">Green</button>

</div>

Step2.

Add CSS

Set the background colour and the size:

body {
  background-color: #EFD5C3;
  height: 100vh;  
}

Add canvas-wrap:

#canvas-wrap {
  position: relative;
  left: 35%;
}

And the canvas with mouse cursor:

canvas {  
  background-color: #fff;
  cursor: url(https://lenadesignorg.files.wordpress.com/2020/06/pencil.png?w=79) 5 80, auto;
  z-index:100;
}

Style the sketchboard:

.sketch-board {
  position: absolute;
  width: 700px;
  height: 500px;
  background-color: #c19875;
  z-index:-5;
  border-radius: 30px;
  left: -80px;
  box-shadow:inset 5px -5px 0 rgba(0,0,0,0.07);
}

.sketch-board:before {
  background-color: #EFD5C3;
  position: absolute;
  width: 50px;
  height: 170px;
  border-radius: 30px;
  content:"";
  left: 30px;
  top: 170px;
  box-shadow:inset 5px -5px 0 rgba(0,0,0,0.07);
}

.paper {
  background-color: #e6e3dc;
  width: 500px;
  height: 350px;
  position: absolute;
  top: 90px;
  left: 120px;
}

.paperclip {
  position: absolute;
  width: 150px;
  height: 40px;
  border: 7px solid #c0c0c0;
  border-radius: 20px;
  left: 200px;
  top: 25px;
  box-shadow: 5px -5px 0 rgba(0,0,0,0.07);
  z-index:1;
}

.paperclip:after {
  position: absolute;
  content:"";
  width: 200px;
  height: 30px;
  top: -20px;
  left:-25px;
  background-color: #8b786d;
  box-shadow:inset 5px -5px 0 rgba(0,0,0,0.07);
  border-radius: 20px;  
}

Style buttons:

.button {
  background-color: #00a6a6;
  border: none;
  border-radius:20px;
  color: #fff;
  padding: 7px 15px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 14px;
  margin: 4px 2px;
  top: 450px;
  left:45px;
  position: relative;
  transition-duration: 0.4s;
}

.button:hover {
  background-color: #73bfb8;
}
JavaScript drawing

Step3.

Add JavaScript/ jQuery

Note: Remember to add jQuery (code above) in the <head> section in your code.

var canvas = document.querySelector('canvas');
  canvas.style.position = 'absolute';
  canvas.style.top = "80px";
  canvas.style.left = "50px";

var ctx = canvas.getContext('2d');
canvas.width = 500;
canvas.height = 350;

var lastX;
var lastY;
var mouseX;
var mouseY;
var canvasOffset = $("#canvas").offset();
var offsetX = canvasOffset.left;
var offsetY = canvasOffset.top;
var isMouseDown = false;
var brushSize = 3;
var brushColor = "#000";

ctx.lineJoin = ctx.lineCap = 'round';

var points = [];


function handleMouseDown(e) {
    mouseX = parseInt(e.clientX - offsetX);
    mouseY = parseInt(e.clientY - offsetY);

    ctx.beginPath();
    if (ctx.lineWidth != brushSize) {
        ctx.lineWidth = brushSize;
    }
    if (ctx.strokeStyle != brushColor) {
        ctx.strokeStyle = brushColor;
    }
    ctx.moveTo(mouseX, mouseY);
    points.push({
        x: mouseX,
        y: mouseY,
        size: brushSize,
        color: brushColor,
        mode: "begin"
    });
    lastX = mouseX;
    lastY = mouseY;
    isMouseDown = true;
}

function handleMouseUp(e) {
    mouseX = parseInt(e.clientX - offsetX);
    mouseY = parseInt(e.clientY - offsetY);

    isMouseDown = false;
    points.push({
        x: mouseX,
        y: mouseY,
        size: brushSize,
        color: brushColor,
        mode: "end"
    });
}


function handleMouseMove(e) {
    mouseX = parseInt(e.clientX - offsetX);
    mouseY = parseInt(e.clientY - offsetY);

    if (isMouseDown) {
        ctx.lineTo(mouseX, mouseY);
        ctx.stroke();
        lastX = mouseX;
        lastY = mouseY;
       
        points.push({
            x: mouseX,
            y: mouseY,
            size: brushSize,
            color: brushColor,
            mode: "draw"
        });
    }
}

$("#canvas").mousedown(function (e) {
    handleMouseDown(e);
});
$("#canvas").mousemove(function (e) {
    handleMouseMove(e);
});
$("#canvas").mouseup(function (e) {
    handleMouseUp(e);
});


function redrawAll() {

    if (points.length == 0) {
        return;
    }

    ctx.clearRect(0, 0, canvas.width, canvas.height);

    for (var i = 0; i < points.length; i++) {

        var pt = points[i];

        var begin = false;

        if (ctx.lineWidth != pt.size) {
            ctx.lineWidth = pt.size;
            begin = true;
        }
        if (ctx.strokeStyle != pt.color) {
            ctx.strokeStyle = pt.color;
            begin = true;
        }
        if (pt.mode == "begin" || begin) {
            ctx.beginPath();
            ctx.moveTo(pt.x, pt.y);
        }
        ctx.lineTo(pt.x, pt.y);
        if (pt.mode == "end" || (i == points.length - 1)) {
            ctx.stroke();
        }
    }
    ctx.stroke();
}

function undoLast() {
    points.pop();
    redrawAll();
}

$("#brushGreen").click(function () {
    brushColor = "#89bd9e";
});
$("#brushYellow").click(function () {
    brushColor = "#fde74c";
});
$("#brushRed").click(function () {
    brushColor = "#e55934";
});
$("#brushBlue").click(function () {
    brushColor = "#5bc0eb";
});

$("#brushBlack").click(function () {
    brushColor = "#000";
});

var interval;
$("#undo").mousedown(function () {
    interval = setInterval(undoLast, 20);
}).mouseup(function () {
    clearInterval(interval);
});

var clear = function(){
  ctx.clearRect(0,0,500,350);
};

$('#clear').on("click",clear);

          <div class="dot six-5"></div>
          <div class="dot six-6"></div>
        </div>
      </div> 
   </div>
   <div id='roll' class='roll-button'><button>Roll dice!</button></div>
  </div> 

Step2.

Add CSS

Set the colour of the background, and the position of the elements.

body {
  background-color: #6a994e;
  perspective: 900px; 
  height: 100vh;
 }

.game {
  position: relative;
  width: 100%;
  height: 50%; 
}

.container {
  position: relative;
  display: inline-block;
  left:40%;
  top: 200px;

}

Style the button:

.roll-button {
  margin-left: 15px; }

button {
  position: absolute;
  left:55%;
  top:-350px;
  padding: 15px 50px;
  color: #fff;
  background-color: #f4d35e;
  border: none;
  font-size: 20px;
  border-radius: 20px; 
  box-shadow: 1px 3px #50514F;
  outline: none;
  transition: .3s; }

button:hover, button:active {
  outline: none;
  background: #50514F;
  cursor: pointer;
  margin-top: 15px; }

Add dice and dots:

.dice {
  position: relative;
  width: 100px;
  height: 100px;
  transform-style: preserve-3d;
  transition: transform 1s; }

.dot {
  position: absolute;
  width: 20px;
  height: 20px;
  margin: -10px 5px 5px -10px;
  border-radius: 20px;
  background-color: #ef233c;
  box-shadow: inset 2px 2px #d90429;}

.dice-one {
  left: 450px; }

.dice-two {
  left: 300px;
  top:-200px;
}

.side {
  position: absolute;
  background-color: #ffF;
  border-radius:5px;
  width: 100px;
  height: 100px;
  border: 1px solid #e5e5e5;
  text-align: center;
  line-height: 2em;
}

.side:nth-child(1) {
  transform: translateZ(3.1em); }

.side:nth-child(6) {
  transform: rotateY(90deg) translateZ(3.1em); }

.side:nth-child(3) {
  transform: rotateY(-90deg) translateZ(3.1em); }

.side:nth-child(4) {
  transform: rotateX(90deg) translateZ(3.1em); }

.side:nth-child(5) {
  transform: rotateX(-90deg) translateZ(3.1em); }

.side:nth-child(2) {
  transform: rotateY(-180deg) translateZ(3.1em); }

.two-1, .three-1, .four-1, .five-1, .six-1 {
  top: 20%;
  left: 20%; }

.four-3, .five-3, .six-4 {
  top: 20%;
  left: 80%; }

.one-1, .three-2, .five-5 {
  top: 50%;
  left: 50%; }

.four-2, .five-2, .six-3 {
  top: 80%;
  left: 20%; }

.two-2, .three-3, .four-4, .five-4, .six-6 {
  top: 80%;
  left: 80%; }

.six-2 {
  top: 50%;
  left: 20%; }

.six-5 {
  top: 50%;
  left: 80%; 
}
3d roll dice javascript

Add .show elements which will spin the dice:

.show-1 {
  transform: rotateX(720deg) rotateZ(-720deg); }

.show-6 {
  transform: rotateX(-900deg) rotateZ(1080deg); }

.show-3 {
  transform: rotateY(-450deg) rotateZ(-1440deg); }

.show-4 {
  transform: rotateY(810deg) rotateZ(720deg); }

.show-5 {
  transform: rotateX(-810deg) rotateZ(-1080deg); }

.show-2 {
  transform: rotateX(450deg) rotateZ(-720deg); }

Step3.

Add JavaScript

Note: To generate a random number of the dice dots we need to use Math.floor(Math.random() * 6) + 1;
If Math.random() were to roll 0.9, we take that and multiply it by 6 which gives us 5.4. Then we take the floor of that which is 5. Then we add 1 which gives us a final result of 6. So the random numbers will only be between 1 and 6.

var elDiceOne       = document.getElementById('dice1');
var elDiceTwo       = document.getElementById('dice2');
var elComeOut       = document.getElementById('roll');

elComeOut.onclick   = function () {rollDice();};

function rollDice() {

  var diceOne   = Math.floor((Math.random() * 6) + 1);
  var diceTwo   = Math.floor((Math.random() * 6) + 1);
 
  console.log(diceOne + ' ' + diceTwo);

  for (var i = 1; i <= 6; i++) {
    elDiceOne.classList.remove('show-' + i);
    if (diceOne === i) {
      elDiceOne.classList.add('show-' + i);
    }
  }

  for (var k = 1; k <= 6; k++) {
    elDiceTwo.classList.remove('show-' + k);
    if (diceTwo === k) {
      elDiceTwo.classList.add('show-' + k);
    }
  } 
  setTimeout(rollDice(), 1000);
}

SVG Handwriting Animation

Practising SVG Path drawing I created the SVG Handwriting Animation.

SVG Handwriting Animation

I’ve tried several ways to make this animation, and I found (in my opinion) the easiest way is to create the text in Adobe Illustrator (or any different program which creates SVG’s) by using the path tools like the Pen tool, or the Pencil tool.

*animation opened in the Safari browser.
To see the live output of the animation click here.

Step1.

Draw your text

This time I used the Pencil tool, and renamed each path (like on the image below, I drew letter L and I named this path as an L). This will make the animation easier to set up later.

I drew the letters one by one but if you want to draw more letters on the same path that will be okay too.

Draw your text and export it like an SVG.(To see how to create an SVG file click here).

Step2.

Add the HTML and paste your SVG code into it:

<div id="container">

</div>

Step3.

Add CSS

Set up the colour and the position of your background, and the elements:

body {
  background-color: #FFD4CA; 
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  
}

#container {
  position: relative;
  cursor:pointer;
  width: 100%;
  max-width: 400px;
  left:-200px;
}

svg {
  width: 100%;
  max-width: 400px;
  padding: 150px; 
  
}

Add your letters(paths):

#L  {
        stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards;
}

To each letter, I added the animation – duration time and animation-delay to make handwriting smoother.

#E {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards .8s;
}

#N {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 1.1s;
}

#A {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 1.3s;
}

#S {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.4s linear forwards 1.8s;
}

#T {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 2.3s;
}

#T2 {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 2.3s;
}

#A2 {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 2.6s;
}

#N2 {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 2.9s;
}

#L2 {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 3.2s;
}

#E2 {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 3.5s;
}

#Y {
  stroke-dasharray: 600;
	stroke-dashoffset: 600;
	animation: lena 1.5s linear forwards 3.8s;
}

Step4.

Add CSS Animation

Add the @keyframes:

@keyframes lena {
	0% {
        stroke-width: 3;
		stroke-dashoffset: 600;
	}
    
    14% {
        stroke-width: 3;
    }
    
    15% {
        stroke-width: 3;
    }
    
	100% {
		stroke-dashoffset: 0;
	}
}

SVG Path Drawing Animation

Path Drawing Animation

The <path> element is used to define a path. It can draw anything you like!

*animation opened in the Safari browser.
To see the live output of the animation click here.

To create SVG Path Drawing Animation we’ll use the same SVG path from the tutorial – SVG Draw on Scroll (which I created in Adobe Illustrator).

Step1.

Add HTML

Get a SVG path (make sure that your shape has a stroke).

SVG Path drawing
<svg id="heart" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 348.43 311.23"><defs><style>.cls-1{fill:none;stroke:#be1622;stroke-miterlimit:10; }</style></defs><title>heart</title><path class="cls-1" d="M340.67,131.25c18.71-30.63,56.59-48.3,92.07-43s66.5,33.36,75.38,68.13c6.22,24.37,2.19,50.32-5.52,74.26-3.88,12.06-8.72,23.89-15.53,34.57s-15.51,20.05-24.35,29.15a861.3,861.3,0,0,1-120.45,103c-32.42-26.2-66.67-45.07-97.36-71.12-14.78-12.55-27.69-27.18-39.75-42.36-15.45-19.44-29.86-40.37-36.88-64.19-8.22-27.87-5.39-59.21,9.37-84.24C194.56,106.85,227,88,260.28,87.45s63.31,15.29,81.13,43.43Z" transform="translate(-163.24 -86.84)"/></svg>

Step2.

Add CSS

We will use the stroke-dasharray property for creating dashes in the stroke of SVG shapes, and also a stroke-dashoffset property to define the location along an SVG path where the dash of a stroke will begin.

body {
  background-color: #2a9d8f; 
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  
}

svg {
  width: 100%;
  max-width: 400px;
  padding: 150px;
  
}

.cls-1{
       stroke-width: 3px;
       stroke-dasharray: 1200;
       stroke-dashoffset: 1200;
       animation: draw 3s linear forwards infinite;
}

@keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}

SVG Draw on Scroll

SVG Draw on Scroll

Using SVG and JavaScript to draw a heart on scroll. Note that it has to be a <path> element:

*animation opened in the Safari browser.
To see the live output click here.

Step1.

Add HTML

Get a SVG path

To make this animation working it has to be a path (any other of SVG elements won’t work).

To create an animation I drew a path (heart) in Adobe Illustrator. To read more about SVG and learn how to create a SVG file click here and here.

<div class="container">
<div class="text"><h1>Scroll to draw</h1></div>
  
  
<svg id="heart" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 348.43 311.23"><defs><style>.heart{fill:none;stroke:#be1622;stroke-miterlimit:10; }</style></defs><title>heart</title><path id="heart1" class="heart" d="M340.67,131.25c18.71-30.63,56.59-48.3,92.07-43s66.5,33.36,75.38,68.13c6.22,24.37,2.19,50.32-5.52,74.26-3.88,12.06-8.72,23.89-15.53,34.57s-15.51,20.05-24.35,29.15a861.3,861.3,0,0,1-120.45,103c-32.42-26.2-66.67-45.07-97.36-71.12-14.78-12.55-27.69-27.18-39.75-42.36-15.45-19.44-29.86-40.37-36.88-64.19-8.22-27.87-5.39-59.21,9.37-84.24C194.56,106.85,227,88,260.28,87.45s63.31,15.29,81.13,43.43Z" transform="translate(-163.24 -86.84)"/></svg>
  
</div>

Step2.

Add CSS

body {
  background: linear-gradient(141deg, #f0f3bd 0%, #02c39a 51%, #00a896 75%);
  display: flex;
  justify-content: center;
  align-items: center;
  height: 5000px;
  
}

.container {
  position: relative; 
}

svg {
  stroke-width: 2px;
  position: fixed;
  width: 200px;
  height: auto;
  margin:0;
  top: 30%;
  left: 45%;
}

.text {
  position: absolute;
  top:-2500px;
  display: block;
  color: white;
  width:400px;
  left:-100px;
  text-shadow: 1px 1px 1px black;
}

Step3.

Add JavaScript

const svg = document.getElementById("heart1");
const length = svg.getTotalLength();


svg.style.strokeDasharray = length;

svg.style.strokeDashoffset = length;

window.addEventListener("scroll", function () {
  const scrollpercent = (document.body.scrollTop + document.documentElement.scrollTop) / (document.documentElement.scrollHeight - document.documentElement.clientHeight);

  const draw = length * scrollpercent;

  svg.style.strokeDashoffset = length - draw;

});
