Animated aquarium with pure CSS

Here is a pure CSS experimental work to create a aquarium. Image / javascript hasn’t been used for aquarium or it’s animation. I have used jQuery only for random air-bubbles. All these animation is created by Pure CSS. Some times ago, I had written a article about “Animated bubbles upwards continuously with pure CSS“. You can also use this trick for air-bubbles.

Animated aquarium with pure CSS

For Creating Aquarium’s water, sand, rocks and plants few lines of HTML required.

The HTML

<div class="bubbles"></div>

<div class="ground"></div>
<div class="rock_1"></div>
<div class="rock_2"></div>
<div class="rock_3"></div>
<div class="rock_4"></div>

</div>
<div class="plant_2_wrap">
    <div class="plant_4"></div>
    <div class="plant_5"></div>
</div>

Now, its CSS turn. I had written about 1040 lines only in CSS for creating these elements.

Animated 3D Background Pattern using HTML5 < canvas >

Hi friends, today we are going to see a cool example of animated 3D Background using HTML5 <canvas> and javascript. The <canvas> element is part of HTML5 and allows for dynamic, script-able rendering of 2D shapes and bitmap images. It is a low level, procedural model that updates a bitmap and does not have a built-in scene graph. The <canvas> element is only a container for graphics… read more @ http://www.css-jquery-design.com/…

3D Parallax effect with CSS, javascript or jQuery

Parallax effect is a long-known and widely used animation effect. Lately, the parallax effect has become a wide-spread and quite a trend element in web design, often referred to as “parallax scrolling”. Internet if full on many great examples of application of this effect in web design. As I planned to create a cool parallax animated background, my first goal was to write the shortest and simplest code to achieve maximum awesomeness! I’ll show you how I did it. In this tutorial, I’ll teach you the simplest parallax scrolling technique. Here, I am going to introduce you, a most flexible/responsive slider i.e. Parallaxfx_DG. It is so easy and useful. I have decided that I will post a page dedicated to this slider with it’s features and API later.

The idea of the parallax effect it in web design is built around giving a page depth by using several layers of images, all moving at different speeds in response to movement of the mouse or mouse scroller, so that a viewer get a full sense of 3D on the page. Parallax scrolling is an interesting technique, where, as you scroll, the background images translate slower than the content in the foreground, creating the illusion of 3D depth. read more @ http://www.css-jquery-design.com/ …

Creating a Puzzle game using jQuery

Today we are making a simple puzzle game called “Doraemon Puzzle”. The purpose of the game is to slide 15 square blocks around to form an image. The goal of this tutorial is to look at this simple browser-based game and explain how it was made line by line. It’s a great way to learn jQuery. For this tutorial, We will use a 2D image of kid’s favorite cartoon “Doraemon” for square-sliding game.  I will go over each line of code to demonstrate the train of thought. I really do believe that breaking this game up into explanations on per-line basis will help you understand how to use jQuery in your own projects.

Concept about creating a Game as a jQuery Plugin

A jQuery plugin is a perfect way to create image slideshows, custom user interface controls and of course browser-based games. We won’t just write JavaScript code here, we will create a jQuery plugin.

A plugin is nothing more than our own custom jQuery method. You know how we have jQuery’s methods .css() and .animate()? Well, jQuery gives us the ability to extend its own functionality with custom methods that we create ourselves. Like the existing jQuery methods, we can apply the method we will create to a jQuery selector.

Well, the game is called “Doraemon Puzzle”, and we want to make our game “embeddable” inside an arbitrary HTML element like <div id=”game_area”>here</div> so we can move it around anywhere on the page.

creating-puzzle-game-with-jquery

The jQuery

We will actually create our own jQuery method and call it .puzzle_dg(). I have already created the plugin “puzzle_dg.min.js“.  Therefore, in order to launch the game inside an HTML element with id “#game_area” we will call this command:

$(window).load(function(){
    $('#game_area').puzzle_dg(140)
});

This will create and attach the game board to the div whose id is “game_area.” Also, each square will become 140 by 140 pixels in width and height based on the only passed parameter. You can re-size the game blocks and area easy by just changing this parameter.

In this tutorial I used the image of a Doraemon cartoon. You can replace it with any image you want.

Executing a custom method as shown in the code above will pass the selector string “#game_area” to our plugin function which grabs the DIV. Inside our custom method, we can refer to that selector/element using the this keyword. And we can also enable jQuery methods on it by passing it to the new jQuery object like so: $(this); — inside the extended function I have created.

The HTML

First, let’s prepare HTML markup for our game.  We have only call <div id="game_area"></div> for creating game area.

We have to include the awesome jQuery library. After including the jQuery library we have to include “puzzle_dg.min.js”  file as game plugin.

<!-- This is where the game will be injected -->
<div id="game_object"></div>

<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="js/main.js"></script>
<script type="text/javascript">$(window).load(function(){
    $('#game_area').puzzle_dg(140)
});</script>

CSS

There are a few styles for our game:

#game_area {
	background-color: #ffffff;
	height: 550px;
	margin: 20px auto;
	position: relative;
	width: 550px;
}
#board div {
	background: url("images/doraemon.jpg") no-repeat scroll 0 0 #ffffff;
	cursor: pointer;
	height: 140px;
	line-height: 140px;
	position: absolute;
	text-align: center;
	width: 140px;
	/* css3 shadow */
    -moz-box-shadow: inset 0 0 20px #2caae7;
	-webkit-box-shadow: inset 0 0 20px #2caae7;
	-ms-box-shadow: inset 0 0 20px #2caae7;
	-o-box-shadow: inset 0 0 20px #2caae7;
	box-shadow: inset 0 0 20px #2caae7;
}

Conclusion

I tried to explain the code to the best of my ability here but some details were skipped because there is so much more to JavaScript. I hope you enjoyed this article. Thanks for reading!

Animate Full-Page Multiple Background images with fade-in & fade-out effect – jQuery

“How to change multiple background-image of body with effects?” – I think this is a major problem which all designers face. You can fade background colors but not background images. The way to work around this is to have your images as <img> tags and hide them by default display:none;. Give your images position:absolute and z-index:-1 so they act like backgrounds and are behind everything else.

Here’s a quick example of multiple images fading one after the other.

jquery-full-page-animated-background-images

The HTML

Html is very simple. Just add a div with multiple images which you want to animate / change in background with fade effects.

<div id="wrap">
<img class="bgfade" src="http://farm9.staticflickr.com/8526/8668341950_182b74faf2_z.jpg">
<img class="bgfade" src="http://farm9.staticflickr.com/8532/8667337535_6da0a9a261_z.jpg">
<img class="bgfade" src="http://farm9.staticflickr.com/8540/8667244539_d227f8c435_z.jpg">
</div>

The CSS

Now, We will use some CSS Technique which will create an illusion like background-image animation. The way to work around this is to have your images as <img> tags and hide them by default “display:none;”. Give your images “position:absolute” and “z-index:-1” so they act like backgrounds and are behind everything else. Now, set css property of div#wrap which includes these images to “position:fixed” and “top:0; left:0;” so that it will fix with page background.

#wrap{
	position:fixed;; 
	z-index:-1; 
	top:0; 
	left:0; 
	background-color:black
}
#wrap img.bgfade{
	position:absolute;
	top:0;
	display:none;
	width:100%;
	height:100%;
	z-index:-1
}

jQuery

Now, it is java-script’s turn. We will calculate browser window’s height & width. After that we will set width/height of div#wrap to browser so that background cover entire webpage. Now we have to animate our images. We will simple use function of fadeIn() and fadeOut() in images for this.

$(window).load(function(){
$('img.bgfade').hide();
var dg_H = $(window).height();
var dg_W = $(window).width();
$('#wrap').css({'height':dg_H,'width':dg_W});
function anim() {
    $("#wrap img.bgfade").first().appendTo('#wrap').fadeOut(1500);
    $("#wrap img").first().fadeIn(1500);
    setTimeout(anim, 3000);
}
anim();})
$(window).resize(function(){window.location.href=window.location.href})

Updated

I have updated the script. Actually, after re-sizing the browser we have to update the width/height of div#wrap. So, I am going to reload this window, when ever browser will re-size. It will help to re-calculate all these and refresh the animation. Div#wrap will re-size according to browser window and play animation smoothly.

Snow-Fall Effect with JavaScript – Creating Merry Christmas Greetings

On the occasion of Christmas and winter Holidays, I thought to wish this festival by create a nice webpage greetings. So, today I had created this Christmas greeting card using snow-fall effect with help of CSS3 and JavaScript. I hope you all will enjoy this holiday and my web-card too :).

Today we will create a Christmas greeting card using CSS3 and jQuery. There are many things we can do with CSS3 and javascript. We’ll use snowfall.dg.js for creating these snow.

snowfall-effect-javascript-christmas-greetings

Features and Principle

Note: Snowfall Plugin is Less than 12Kb in size. There are many options for customize and use this plugin as per your requirement. Some features are:

  • No need to add any image for snow.
  • No need to add any JavaScript library.
  • You can use any html element in place of snow.
  • Change the Color of Snow by using hexadecimal value.
  • Also support in iPhone, iPad and Mobile devices.
  • Snow-fall movement with mouse/cursor.
  • Stick on bottom.
  • Snow melt effect.
  • Twinkle effect – you can use this also if you want star-fall 🙂
  • More options..

What this script does is adds snow-fall to the body. You can find more options in snowfall.dg.js.

The CSS

No special css required for snow fall effect. But in this greeting card, I have used css for background and my greeting message.

body{
         font-size:18px; 
         background:#badaf3 url(merry_chirstmas-wide.jpg) 100% 0 no-repeat; 
         background-size:cover; 
         font-family: 'IM Fell Double Pica', georgia, serif;
}
#welcome{
         font-size:2em; 
         width:40%; 
         margin:4%; 
         text-align:center; 
         background-color:#fff; 
         -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)";
         background:rgba(255,255,255,.75); 
         border-radius:10px; 
         box-shadow:4px 4px 10px 0 rgba(20,20,20,.6); 
         text-shadow: 2px 2px 3px #fff; 
         font-style:italic; 
         padding:1em; 
         color:#700; 
         color:rgba(120,0,20,.9)
}

The Html

<div id="welcome">May the miracle of Christmas fill your heart with 
warmth & love. 
Christmas is the time of giving and sharing.
It is the time of loving and forgiving. 
Hope you and your family have
wonderful Holiday... &... Merry Christmas to Everyone! </div>

Snowfall – The javascript

We have to add this snowfall.dg.js in body. I always prefer to use JavaScript files before close of body tag.

<script type="text/javascript" src="snowfall.dg.js"><script>

view demo

Updated!

I have updated this greetings with Jingle bells music and Html5 audio tags. now our Html is

<div id="welcome">May the miracle of Christmas fill your heart with 
warmth & love. 
Christmas is the time of giving and sharing.
It is the time of loving and forgiving. 
Hope you and your family have
wonderful Holiday... &... Merry Christmas to Everyone! </div>
 <audio autoplay="true" loop="true">
   <source src="jingle_bells_merry.ogg" type="audio/ogg">
   <source src="jingle_bells_merry.mp3" type="audio/mpeg">
Your browser does not support the audio element (HTML5). Please update your Browser.
 </audio>

Merry Christmas

I hope you like the result and don’t hesitate to share your thoughts about it. Thanks for reading!

Random 3D Explosions, 3D clouds – Effects with CSS 3D and jQuery

Introduction

This tutorial will try to guide you through the steps to create a 3D-like, explosions in sky or billboard-based clouds. There are a few advanced topics, mainly how 3D transformations via CSS properties work. If you want to find more information, this is a nice place to begin.

If you’re in a hurry, just check the final result.

css-3d-explosive-clouds

The tutorial is divided into sections, each with a different step to understand and follow the process, with HTML, CSS and Javascript blocks. Each step is based on the previous one, and has a link to test the code. The code in the tutorial is a simplified version of the demos, but the main differences are documented on every section.

HTML

First, we need two div elements: viewport and world. All the rest of the elements will be dynamically created.

Viewport covers the whole screen and acts as the camera plane. Since in CSS 3D Transforms there is no camera per se, think of it as a static sheet of glass through which you see a world that changes orientation relative to you. We’ll position all our world objects (or scene) inside it, and that’s what will be transformed around.

World is a div that we are going to use to anchor all our 3D elements. Transforming (rotating, translating or scaling) world will transform all our elements. For brevity and from here on, I’m using non-prefixed CSS properties. Use the vendor prefix (-webkit, -moz, -o, -ms, etc.) where appropriate.

This is all the markup we’ll need:

<div id="viewport">
    <div id="world"></div>
</div>

CSS

These next are our two CSS definitions. It’s very important to center the div that contains our scene (world in our case) in the viewport, or the scene will be rendered with an offset! Remember that you are still rotating an element that is positioned inside the document, exactly like any other 2D element.

#viewport {
	-webkit-perspective: 1000; -moz-perspective: 1000; -o-perspective: 1000; 
	position: absolute; 
	left: 0; 
	top: 0; 
	right: 0; 
	bottom: 0; 
	overflow: hidden;
	background-image: linear-gradient(bottom, rgb(69,132,180) 28%, rgb(31,71,120) 64%);
	background-image: -o-linear-gradient(bottom, rgb(69,132,180) 28%, rgb(31,71,120) 64%);
	background-image: -moz-linear-gradient(bottom, rgb(69,132,180) 28%, rgb(31,71,120) 64%);
	background-image: -webkit-linear-gradient(bottom, rgb(69,132,180) 28%, rgb(31,71,120) 64%);
	background-image: -ms-linear-gradient(bottom, rgb(69,132,180) 28%, rgb(31,71,120) 64%);
	background-image: -webkit-gradient(
			linear,
			left bottom,
			left top,
			color-stop(0.28, rgb(69,132,180)),
			color-stop(0.64, rgb(31,71,120))
	);
}

#world {
	position: absolute; 
	left: 50%; 
	top: 50%; 
	margin-left: -256px; 
	margin-top: -256px; 
	height: 512px; 
	width: 512px; 
	-webkit-transform-style: preserve-3d; 
	-moz-transform-style: preserve-3d; 
	-o-transform-style: preserve-3d; 
	pointer-events: none;
}

CSS For Adding Clouds Base

Now we start adding real 3D content. We add some new div which are positioned in the space, relatively to world. It’s esentially adding several absolute-positioned div as children of world, but using translate in 3 dimensions instead of left and top. They are centered in the middle of world by default. The width and height don’t really matter, since these new elements are containers for the actual cloud layers. For commodity, it’s better to center them (by setting margin-left and margin-top to negative half of width and height).

.cloudBase {
		position: absolute; 
		left: 256px; 
		top: 256px; 
		width: 20px; 
		height: 20px; 
		margin-left: -10px; 
		margin-top: -10px
	}

CSS for Clouds Layer

Now things start getting interesting. We add several absolute-positioned .cloudLayer div elements to each .cloudBase. These will hold our cloud textures.

.cloudLayer {
		position: absolute; 
		left: 50%; 
		top: 50%; 
		width: 256px; 
		height: 256px; 
		margin-left: -128px; 
		margin-top: -128px; 
		-webkit-transition: opacity .5s ease-out; 
		-moz-transition: opacity .5s ease-out; 
		-o-transition: opacity .5s ease-out;
	}

jQuery (JavaScript)

We add generate() and createCloud() functions to populate world. Note that random_{var} are not real variables but placeholder names for the real code, which should return a random number between the specified range.

var layers = [],
	objects = [],
	textures = [],

	world = document.getElementById( 'world' ),
	viewport = document.getElementById( 'viewport' ),

	d = 0,
	p = 400,
	worldXAngle = 0,
	worldYAngle = 0,
	computedWeights = [];

	viewport.style.webkitPerspective = p;
	viewport.style.MozPerspective = p;
	viewport.style.oPerspective = p;
	textures = [
		{ name: 'white cloud', 	file: 'cloud.png'	, opacity: 1, weight: 0 },
		{ name: 'dark cloud', 	file: 'darkCloud.png'	, opacity: 1, weight: 0 },
		{ name: 'smoke cloud', 	file: 'smoke.png'	, opacity: 1, weight: 0 },
		{ name: 'explosion', 	file: 'explosion.png'	, opacity: 1, weight: 0 },
		{ name: 'explosion 2', 	file: 'explosion2.png'	, opacity: 1, weight: 0 },
		{ name: 'box', 		file: 'box.png'		, opacity: 1, weight: 0 }
	];

	function setTextureUsage( id, mode ) {
		var modes = [ 'None', 'Few', 'Normal', 'Lot' ];
		var weights = { 'None': 0, 'Few': .3, 'Normal': .7, 'Lot': 1 };
		for( var j = 0; j < modes.length; j++ ) {
			var el = document.getElementById( 'btn' + modes[ j ] + id );
			el.className = el.className.replace( ' active', '' );
			if( modes[ j ] == mode ) {
				el.className += ' active';
				textures[ id ].weight = weights[ mode ];
			}
		}
	}
	setTextureUsage( 0, 'Few' );
	setTextureUsage( 1, 'Few' );
	setTextureUsage( 2, 'Normal' );
	setTextureUsage( 3, 'Lot' );
	setTextureUsage( 4, 'Lot' );

	generate();

	function createCloud() {

		var div = document.createElement( 'div'  );
		div.className = 'cloudBase';
		var x = 256 - ( Math.random() * 512 );
		var y = 256 - ( Math.random() * 512 );
		var z = 256 - ( Math.random() * 512 );
		var t = 'translateX( ' + x + 'px ) translateY( ' + y + 'px ) translateZ( ' + z + 'px )';
		div.style.webkitTransform = t;
		div.style.MozTransform = t;
		div.style.oTransform = t;
		world.appendChild( div );

		for( var j = 0; j < 5 + Math.round( Math.random() * 10 ); j++ ) {
			var cloud = document.createElement( 'img' );
			cloud.style.opacity = 0;
			var r = Math.random();
			var src = 'troll.png';
			for( var k = 0; k < computedWeights.length; k++ ) { 
				if( r >= computedWeights[ k ].min && r <= computedWeights[ k ].max ) { 					
( function( img ) { img.addEventListener( 'load', function() {
 						img.style.opacity = .8;
					} ) } )( cloud );
 					src = computedWeights[ k ].src; 
}} 
cloud.setAttribute( 'src', src ); 
cloud.className = 'cloudLayer'; 		 			
var x = 256 - ( Math.random() * 512 ); 
var y = 256 - ( Math.random() * 512 ); 
var z = 100 - ( Math.random() * 200 ); 
var a = Math.random() * 360; 
var s = .25 + Math.random(); 
x *= .2; y *= .2; 
cloud.data = {x: x, y: y, z: z, a: a, s: s, speed: .1 * Math.random()}; 
var t = 'translateX( ' + x + 'px ) translateY( ' + y + 'px ) translateZ( ' + z + 'px ) rotateZ( ' + a + 'deg ) scale( ' + s + ' )'; 
cloud.style.webkitTransform = t; 
cloud.style.MozTransform = t; 			
cloud.style.oTransform = t; 			
div.appendChild( cloud ); 			
layers.push( cloud ); 		} 		 		
return div; 	 	
function generate() { 		
objects = []; 		
if ( world.hasChildNodes() ) { 			
while ( world.childNodes.length >= 1 ) {
				world.removeChild( world.firstChild );       
			} 
		}
		computedWeights = [];
		var total = 0;
		for( var j = 0; j < textures.length; j++ ) { 			
if( textures[ j ].weight > 0 ) {
				total += textures[ j ].weight;
			}
		}
		var accum = 0;
		for( var j = 0; j < textures.length; j++ ) { 			
if( textures[ j ].weight > 0 ) {
				var w = textures[ j ].weight / total;
				computedWeights.push( {
					src: textures[ j ].file,
					min: accum,
					max: accum + w
				} );
				accum += w;
			}
		}
		for( var j = 0; j < 5; j++ ) {
			objects.push( createCloud() );
		}
	}

Result

For the final effect, we fill cloudLayer div for an img with a cloud texture. The textures should be PNG with alpha channel to get the effect right.

css-3d-explosive-clouds

Conclusion

Of course, you can use any texture or set of textures you want: smoke puffs, plasma clouds, green leaves, flying toasters… Just change the background-image that a specific kind of cloud layer uses. Mixing different textures in different proportions gives interesting results.

Adding elements in random order is fine, but you can also create ordered structures, like trees, duck-shaped clouds or complex explosions. Try following a 3D curve and create solid trails of clouds. Create a multiplayer game to guess the shape of a 3D cloud. The possibilities are endless!

I hope it’s been an interesting tutorial and not too hard to follow.
