CSS Techniques – Absolute Horizontal And Vertical Centering In CSS

We’ve all seen margin: 0 auto; for horizontal centering, but margin: auto;has refused to work for vertical centering… until now! But actually (spoiler alert!)

I’m not the pioneer of this method, and it may even be a common technique, however, most vertical centering articles never mention it and I had never seen it until I dug through the comments section of  read more @ http://www.css-jquery-design.com/…

.Absolute-Center {
  margin: auto;
  position: absolute;

Javascript or jQuery Fullscreen browser window – Html5 technology

The new html5 technology – fullscreen API gives us an easy way to present a web page content in full-screen mode. We are about to give you detailed information about the fullscreen mode. Just try to imagine about all possible advantages which you can get using this technology – full-screen photo albums, videos, and even games. But before we describe this new technology, I have to note that this technology is experimental, and not all the browsers support it.

Starting the full-screen mode

Due to the fact that this mode is supported by different browsers differently, we have to foresee all the cases: 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!

Responsive jQuery Banner Slider with Pagination circles – Responsive_DG_Slider

After working on Responsive_DG_Slider,  which is a most flexible/responsive image slider with different random transition effects. After full-screen example, I am sharing another example with different transition effects. It is very easy to implement.

Configuring Your Slider

As we have done earlier, configuring the slider is very simple, you just need to place your images and call the initializer function and your slider is ready. Here’s how you can do this for liquid/responsive images slider with pagination.

The HTML

<div class="fluid_container">
        <div class="fluid_dg_wrap fluid_dg_charcoal_skin" id="fluid_dg_wrap_1">
            <div data-thumb="slides/thumbs/1.jpg" data-src="slides/1-1280x720.jpg">
                <div class="fluid_dg_caption fadeFromBottom">
                    Responsive_DG_Slider is a responsive/adaptive slideshow. <em>Try to resize the browser window</em>
                </div>
            </div>
            <div data-thumb="slides/thumbs/2.jpg" data-src="slides/2-1280x720.jpg">
                <div class="fluid_dg_caption fadeFromBottom">
                    It uses a light version of jQuery mobile, <em>navigate the slides by swiping with your fingers</em>
                </div>
            </div>
            <div data-thumb="slides/thumbs/3.jpg" data-src="slides/3-1280x720.jpg">
                <div class="fluid_dg_caption fadeFromBottom">
                    <em>It's <strong>completely free</strong>, with tons of effects, Prev / next, pager, Start / Stop / Auto control controls and lot of customizable options.</em>
                </div>
            </div>
            <div data-thumb="slides/thumbs/4.jpg" data-src="slides/4-1280x720.jpg">
                <div class="fluid_dg_caption fadeFromBottom">

                </div>
            </div>
        </div>
    </div>

The CSS

First we have to link it’s default css file.

<link rel='stylesheet' id='fluid_dg-css'  href='css/fluid_dg.css' type='text/css' media='all'>

Now some customization:

.fluid_container {
			margin: 0 auto;
			width: 100%;
		}

The jQuery

First, We have to add some jQuery library.

 <script type='text/javascript' src='http://code.jquery.com/jquery-1.6.2.min.js'></script>
    <script type='text/javascript' src='Scripts/jquery.mobile.customized.min.js'></script>
    <script type='text/javascript' src='Scripts/jquery.easing.1.3.js'></script> 
    <script type='text/javascript' src='Scripts/fluid_dg.min.js'></script>

After adding all these library we have to initiate the Responsive_DG_Slider.

jQuery(document).ready(function(){
		jQuery(function(){			
			jQuery('#fluid_dg_wrap_1').fluid_dg({thumbnails: true,height:"25%"});
		}); })

You have done!!

Now enjoy your liquid slider. Please feel free to comment and share your thoughts/ideas about the result.

Full-Screen Responsive jQuery Banner Slider – Responsive_DG_Slider

After working on responsive or flexy designs, I found some serious issues about fixed width in most of images/banner sliders which I have got online. So, I thought to develop a liquid/responsive images slider with different transition effects. Here, I am going to introduce you, a most flexible/responsive slider i.e. Responsive_DG_Slider. 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.

Here I am showing It’s full screen responsive image slider functionality powered by the fantastic java-script library jQuery. With a nice and simple design it adjusted automatically to the width of your browser screen. Image sliders add life and interactivity to your web contents. But creating an image slider from scratch is not that easy. You need some good programming skills to create your own slider. If you are not the programmer or you just don’t want to re-invent the wheel, Responsive_DG_Slider is for you. Previously, I have already developed a very simple and useful slider i. e. jQuery – DG_Slider.
jquery-responsive-slider

Configuring Your Slider

Configuring the slider is very simple, you just need to place your images and call the initializer function and your slider is ready. Here’s how you can do this for full-screen.

The HTML

For develping a Full-Screen Background image slider you need to create the necessary HTML markups for your slider and then add references to necessary script files.

<div class="fluid_container">
        <div class="fluid_dg_wrap fluid_dg_emboss pattern_1 fluid_dg_white_skin" id="fluid_dg_wrap_4">
            <div data-thumb="slides/thumbs/1.jpg" data-src="slides/1-1280x720.jpg"></div>
            <div data-thumb="slides/thumbs/2.jpg" data-src="slides/2-1280x720.jpg"></div>
            <div data-thumb="slides/thumbs/3.jpg" data-src="slides/3-1280x720.jpg"></div>
            <div data-thumb="slides/thumbs/4.jpg" data-src="slides/4-1280x720.jpg"></div>
            <div data-thumb="slides/thumbs/5.jpg" data-src="slides/5-1280x720.jpg"></div>
            <div data-thumb="slides/thumbs/6.jpg" data-src="slides/6-1280x720.jpg"></div>
        </div>
</div>

The CSS

We have to link it’s default css file.

<link rel='stylesheet' id='fluid_dg-css'  href='css/fluid_dg.css' type='text/css' media='all'>

After attaching the default CSS, now we will customize it according to our requirement.

.fluid_container {
	bottom: 0; height: 100%; left: 0; position: fixed; right: 0; top: 0; z-index: 0;
}
#fluid_dg_wrap_4 {
	bottom: 0; height: 100%; left: 0;
	margin-bottom: 0 !important;
	position: fixed; right: 0; top: 0;
}
.fluid_dg_bar {
	z-index: 2;
}
.fluid_dg_prevThumbs, 
.fluid_dg_nextThumbs, 
.fluid_dg_prev, 
.fluid_dg_next, 
.fluid_dg_commands, 
.fluid_dg_thumbs_cont {
	background: #222;
	background: rgba(2, 2, 2, .7);
}
.fluid_dg_thumbs {
	margin-top: -100px; position: relative; z-index: 1;
}
.fluid_dg_thumbs_cont {
	border-radius: 0;
	-moz-border-radius: 0;
	-webkit-border-radius: 0;
}
.fluid_dg_overlayer {
	opacity: .1;
}

The jQuery

First, We have to add some jQuery library.

    <script type='text/javascript' src='http://code.jquery.com/jquery-1.6.2.min.js'></script>
    <script type='text/javascript' src='Scripts/jquery.mobile.customized.min.js'></script>
    <script type='text/javascript' src='Scripts/jquery.easing.1.3.js'></script> 
    <script type='text/javascript' src='Scripts/fluid_dg.min.js'></script>

After adding all these library we have to initiate the Responsive_DG_Slider. In this slider’s API we have several customization options. Here we are customizing some options according to this full-screen slider.

jQuery(document).ready(function(){
	jQuery(function(){			
		jQuery('#fluid_dg_wrap_4').fluid_dg({height: 'auto', loader: 'bar', pagination: false, thumbnails: true, hover: false, opacityOnGrid: false, imagePath: ''});
	}); 
})

Done!

CSS3 3D effect, Shine text with css3 keyframe animation, Scrolling Page Background with jQuery – Happy New Year

On the occasion of New Year 2013, I thought to wish this festival by creating a nice webpage greeting. So, today I created this greeting card using 3D  and shining text effect with the help of CSS3, and scrolling background with JavaScript. I hope you all will enjoy this holiday as well as my web-card too :) .

Introduction

Greeting, today we are going to make a scrolling background effect. This script will move the background of any html tag, either vertically or horizontally. I used this script in one of my greeting card too which has a blue sky with clouds and it makes the whole website came alive. I think that’s pretty impressive. In this card you will find texts with different CSS effects like: 3D emboss, continuous spotlight shine effect, text shadow etc.

3d-shine-text-css3-scrolling-background-happy-new-year

The CSS

I have Used multiple text-shadows to create 3D text on any HTML element. No extra HTML, no extra headaches, just awesomesauce.
Works in the latest builds of Safari, Chrome, Firefox, and Opera.

h1 {
  margin:1.2em auto;
  font: bold 100px/1 "Helvetica Neue", Helvetica, Arial, sans-serif;
  color: #fff;
  text-shadow: 0 1px 0 #cccccc, 0 2px 0 #c9c9c9, 0 3px 0 #bbbbbb, 0 4px 0 #b9b9b9, 0 5px 0 #aaaaaa, 0 6px 1px rgba(0, 0, 0, 0.1), 0 0 5px rgba(0, 0, 0, 0.1), 0 1px 3px rgba(0, 0, 0, 0.3), 0 3px 5px rgba(0, 0, 0, 0.2), 0 5px 10px rgba(0, 0, 0, 0.25), 0 10px 10px rgba(0, 0, 0, 0.2), 0 20px 20px rgba(0, 0, 0, 0.15);
  -webkit-transition: .2s all linear;
}

Text shine Effect created with WebKit-specific CSS3 properties. You’ll need Safari or Chrome to enjoy key-frame animation.

p.shine{
    font-size: 3em;
    margin: 0 auto; padding:0;
    width: 95%;
}
.shine{
    background: #222 -webkit-gradient(linear, left top, right top, from(#ccc), to(#fff), color-stop(1, #f0f)) 0 0 no-repeat;
    background-size: 400px; -webkit-background-size: 400px; 
    -moz-background-size: 400px; -o-background-size: 400px;    
    color: rgba(255, 255, 255, 0.7);	
    background-clip: text; -webkit-background-clip: text; 
        -moz-background-clip: text; -o-background-clip: text;	
	-webkit-animation: shine 2s infinite;
	-moz-animation: shine 2s infinite;
	-o-animation: shine 2s infinite;
	-ms-animation: shine 2s infinite;
	animation: shine 2s infinite; 
}

@-webkit-keyframes shine{
    0%{background-position: top left;}
    100%{background-position: top right;}
}
@-moz-keyframes shine{
    0%{background-position: top left;}
    100%{background-position: top right;}
}
@-o-keyframes shine{
    0%{background-position: top left;}
    100%{background-position: top right;}
}
@keyframes shine{
    0%{background-position: top left;}
    100%{background-position: top right;}
}

For page background I used cloud in png format.

body{background:url(bg_clouds.png) 0 0}

The HTML

<h1>Happy New Year 2013</h1>
<p class="shine">The New Year is the time of unfolding horizons and the realization of dreams, may you rediscover new strength and garner faith with you, and be able to rejoice in the simple pleasures that life has to offer and put a brave front for all the challenges that may come your way.<br>
Wishing you a lovely New Year..</p>

The JavaScript – jQuery

We have to add jquery library in body first, after that we animate our page background with css background-position properties. I always prefer to use JavaScript files before close of body tag.

<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
<script type="text/javascript">var scrollSpeed = 70; 
    var current = 0;
    function bgscroll(){
        current -= 1;   
        // move the background with backgrond-position css properties
        $('body').css("backgroundPosition", 1 ? current+"px 0" : "0 " + current+"px");   
    }
     setInterval(bgscroll, scrollSpeed);   </script>

Happy New Year!
