Animated bubbles upwards continuously with pure CSS

Here is a pure CSS experimental work to create floating bubbles without using JavaScript. These animated bubbles are also with popping effect. All these animation is created by Pure CSS.

For our little demo, we use a simple image for the conical flask and then create the bubbles entirely with markup and CSS. read more @ http://www.css-jquery-design.com/…

Animated bubbles upwards continuously with pure CSS

The HTML

<div id="beaker">
  <span class="bubble">
    <span class="glow"> </span>
  </span>
</div>

With our bubbles all made, now we need them to act like bubbles. We could use JavaScript but that’s no fun. Just use CSS! read more @ http://www.css-jquery-design.com/…read-more-button

CSS3 Modal Window Popups – sliding forms with fancybox effect

Today, I will describe you how to create cool CSS3 modal popup windows (or boxes). Literally, not so long ago, in order to achieve such effects, we used jQuery. But, as it turned out, CSS3 has all the necessary tools for making modal windows too. In our demonstration I have prepared single page with two popup elements: join form and login form. Welcome to test results (domo) and understand how it was made. read more @ http://www.css-jquery-design.com/…

HTML

First, lets create the main HTML markup. As you can see – the structure is quite easy. Here are one panel with buttons and two popups. Each of them contains own overlay DIV element and popup DIV element with some content inside and ‘close’ button.  read more @ http://www.css-jquery-design.com/…

Animated Color wheel spinning with CSS3 Keyframes animation, Transform and Transition

I have done some experimental work to create CSS3 Animation without using JavaScript. I end up creating some animations using CSS3 Keyframes and Transform and like to share. I have done this animation using border-color tricks and CSS Transform: i.e. CSS scale and CSS3 rotation.

Note: Before going I like to make something clear, Internet Explorer 10, Firefox, and Opera supports the @keyframes rule and animation property. Chrome and Safari requires the prefix -webkit- in css.

Important: Internet Explorer 9, and earlier versions, does not support the @keyframe rule or animation property.

css3-keyframes-color-wheel-animation

The HTML

<div id="colorWheel">
    <span class="color01"></span>
    <span class="color02"></span>
    <span class="color03"></span>
    <span class="color04"></span>
    <span class="color05"></span>
    <span class="color06"></span>
    <span class="color07"></span>
    <span class="color08"></span>
    <span class="color09"></span>
    <span class="color10"></span>
</div>

The CSS

Now, We will use some CSS Technique using border-color tricks and CSS3 rotation. I have created this color cycle without using any image.  I have done a cool rotating wheel animation  using @keyframes animation.

Pure CSS3 Animated Polaroid Gallery

Normally, Polaroid Gallery is a CSS3 & jQuery Image Gallery plugin for Media Library. It is used to overlay images as Polaroid pictures on the current page or post.

It’s a sure thing that CSS3 features like transitions, animations and transforms can add extra spice to your designs. In this article you will see how you can build an awesome CSS3 animated  Polaroid pictures gallery with some of these cool features.  This is something I wished to do for a while and I finally made it.css3-animated-polaroid-gallery

Cool Typography Effects With CSS3 and jQuery

Today we will create a set of nice typography effects for big headlines using CSS3 and jQuery. There are many things we can do with CSS3 animations and transitions and we’ll explore some of the possibilities.

Today we will create a set of nice typography effects for big headlines using CSS3 and jQuery. There are many things we can do with CSS3 animations and transitions and we’ll explore some of the possibilites.

We’ll be using jquery.DG_lettering.js in order to style single letters of the words we’ll be having in our big headlines.

typography-effects-with-css-jquery

THE HTML

The structure will simply be an h2 element with an anchor inside. We’ll wrap the headline in a container:

<div id="letter-container" class="letter-container">
    <h2><a href="#">Sun</a></h2>
</div>

Then we’ll call the jquery.DG_lettering.js plugin, so that every letter gets wrapped in a span.

This example looks crazy: we’ll create a text shadow that “elevates” the letters. We’ll also create a pseudo element which has a superhero as background.

THE CSS

.letter-container h2 a:before{
    content: '';
    position: absolute;
    z-index: 0;
    width: 525px;
    height: 616px;
    background: transparent url(superhero.png) no-repeat center center;
    background-size: 40%;
    top: 0px;
    left: 50%;
    margin-left: -277px;
    transition: all 0.3s ease-in-out;
}

On hover, we will animate the background size to make the superhero larger:

.letter-container h2 a:hover:before{
    background-size: 100%;
}

The span will have the text-shadow that “elevates” the letters and on hover, we will move the letter down by adding a padding and changing the shadow:

.letter-container h2 a span{
    color: #ff3de6;
    float:left;
    position: relative;
    z-index: 100;
    transition: all 0.3s ease-in-out;
    text-shadow:

Animated 3D Bouncing Ball with CSS3, Html5

Hi guys! Today we are going to see another great example of how to use the power of CSS3. We will start by creating a very cool and realistic 3D ball with pure CSS3 properties, and add a little CSS3 animations for giving the ball a “bouncing” effect.

Please note: the result of this tutorial will only work as intended in browsers that support the respective CSS properties (gradient, shadow, border-radius, keyframe animation).css-3d-bouncing-ball

THE HTML

Let’s start with some very basic HTML:

<div id="ballWrapper">
     <div id="ball"></div>
     <div id="ballShadow"></div>
</div>

What we have here are 3 simple DIV elements. “#ballWrapper” is the main DIV which wraps the ball. This DIV will determine the ball’s position and height on the screen. Next, we have the “#ball” element which is the ball markup, and finally there is the “#ballShadow” which holds the ball’s shadow separately from the ball itself.

THE CSS

First, we’ll want to set a basic width and height to our ‘#ballWrapper’ DIV. It will help us position it to the center of the screen:

#ballWrapper {
    width: 140px;
    height: 300px;
    position: fixed;
    left: 50%;
    top: 50%;
    margin: -150px 0 0 -70px;
}

Note that I gave the DIV both top and left position properties of  ‘50%’, and a negative top and left margin which is calculated to be exactly half of the original height and width of the DIV. That way we can center the ball on the screen.

Next in line, let’s give our ball some styles (grow up, it’s not that funny… :])

#ball {
    width: 140px;
    height: 140px;
    border-radius: 70px;
    background: linear-gradient(top,  rgba(187,187,187,1) 0%,rgba(119,119,119,1) 99%);
    box-shadow: inset 0 -5px 15px rgba(255,255,255,0.4), 
                inset -2px -1px 40px rgba(0,0,0,0.4), 
                0 0 1px #000;   
}

We are giving the ball equal width and height and a ‘border-radius‘ property with a value of  ’70px’ (which is half of the original width and height we’ve set) so it will be a ball and not an oval shape.

Another thing you’ll notice is the background. I gave the ball’s element a linear background and 3 different box shadow levels so it would get the 3D effect. The first box shadow level is for the dark shadowing at the bottom of the ball (see image). Then, we have the second level that is responsible for the blurry glow – again, at the bottom of the ball. Finally the third level is a hardly noticeable blurry shadow behind the contours of the ball.

If you take a look at the ball you’ll notice that there is another small oval shape on top of the ball that gives it a reflection effect. Here is how I created it:

#ball::after {
    content: "";
    width: 80px; 
    height: 40px; 
    position: absolute;
    left: 30px;
    top: 10px;  
    background: linear-gradient(top,  rgba(232,232,232,1) 0%,rgba(232,232,232,1) 1%,rgba(255,255,255,0) 100%);
    border-radius: 40px / 20px; 
}

I used the CSS pseudo element ::after and gave it a linear gradient with an opacity. In addition, I’ve set the border radius to  ’40px / 20px’ so it has an oval shape.
Next, let’s handle the ball’s shadow:

#ballShadow {
    width: 60px;
    height: 75px;
    position: absolute;
    z-index: 0;
    bottom: 0;
    left: 50%;
    margin-left: -30px;
    background: rgba(20, 20, 20, .1);
    box-shadow: 0px 0 20px 35px rgba(20,20,20,.1);
    border-radius: 30px / 40px; 
}

view demo

Again, I used the same properties for centering the shadow, but this time I pinned it to the bottom of ‘#ballWrapper’. I also added a semi-transparent background to it, a fitting box shadow and a border radius.

THE BOUNCING ANIMATION

Now let’s take a look at the fun stuff…

I’ll start by adding the animation property to our ball:

#ball {
    animation: jump 1s infinite;
}

All I did was to define the animation’s name (jump), the animation’s duration (1 second) and how many times the animation will happen – in our case we use ‘infinite’ which means that it will run forever.
The animation itself:

@keyframes jump {
    0% {
        top: 0;
    }
    50% {
        top: 140px;
        height: 140px;
    }
    55% {
        top: 160px; 
        height: 120px; 
        border-radius: 70px / 60px;
    }
    65% {
        top: 120px; 
        height: 140px; 
        border-radius: 70px;
    }
    95% {
        top: 0;
    }
    100% {
        top: 0;
    }
}

So, basically what I’m doing here is to play with the ‘top’ position property of the ball.  Starting from 0, through 160 and back to 0. You’ll notice that in the middle of the animation I’m also playing with the ‘border-radius’ property – that way I handle the “impact” of the ball on the ground.

And now the ball’s shadow; first let’s add the shadow’s relevant animation property:

#ballShadow {
    animation: shrink 1s infinite;
}

I used the same values that I used with the ball, only with a different keyframes animation called shrink which looks as follows:

@-keyframes shrink {
    0% {
        bottom: 0;
        margin-left: -30px;
        width: 60px;
        height: 75px;
        background: rgba(20, 20, 20, .1);
        box-shadow: 0px 0 20px 35px rgba(20,20,20,.1);
        border-radius: 30px / 40px;
    }
    50% {
        bottom: 30px;
        margin-left: -10px;
        width: 20px;
        height: 5px;
        background: rgba(20, 20, 20, .3);
        box-shadow: 0px 0 20px 35px rgba(20,20,20,.3);
        border-radius: 20px / 20px;
    }
    100% {
        bottom: 0;
        margin-left: -30px;
        width: 60px;
        height: 75px;
        background: rgba(20, 20, 20, .1);
        box-shadow: 0px 0 20px 35px rgba(20,20,20,.1);
        border-radius: 30px / 40px;
    }
}

In the shadow’s animation I played with different properties then in the ball’s animation. In order to give it all a realistic effect when it comes to the ball’s distance from the floor, I needed to animate the shadow width, height and opacity. While the ball is close to the floor, the shadow needs to be darker and smaller. When the ball jumps up, the shadow should be lighter and bigger.

Last, but not least, let’s add the “click effect” to the ball which makes it appear as if it moves away from us when we click and hold. To achieve this effect, all we have to use is the ‘:active’ pseudo-class, add a transition and play with the CSS3 transform ‘scale’ property like this:

#ballWrapper {
    transform: scale(1);
    transition: all 5s linear 0s;
}

#ballWrapper:active {
    transform: scale(0);
}

The transition from a transform value of scale(1) to scale(0) will make it look as if the element is moving away from you.

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.

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.
