Page loading effect using jQuery and CSS3

In this tutorial we will learn how to load your contents in your website with some user experience to make it feel lively. In this we will load the contents as they scroll down. The contents will come out with a fadeIn effect and then it will move up slightly.

Step 1 : Include the Js files
You need to include the latest Jquery Library file.Here I used is
Then you need to include the wayfinder.js file to calculate the scroll amount.
<script src="js/wayfinder.js" ></script>
Step 2: Add the following CSS
.load-animate {opacity: 0;}
 
.fadeInUp {-webkit-animation-name: fadeInUp;-moz-animation-name: fadeInUp;-o-animation-name: fadeInUp;animation-name: fadeInUp;}
 
.animated {-webkit-animation-duration: 1s;-moz-animation-duration: 1s;-o-animation-duration: 1s;animation-duration: 1s;
 
-webkit-animation-fill-mode: both;-moz-animation-fill-mode: both;-o-animation-fill-mode: both;animation-fill-mode: both;
 
}
 
@-webkit-keyframes fadeInUp{0%{opacity:0;-webkit-transform:translateY(20px)}100%{opacity:1;-webkit-transform:translateY(0)}}@-moz-keyframes fadeInUp{0%{opacity:0;-moz-transform:translateY(20px)}100%{opacity:1;-moz-transform:translateY(0)}}@-o-keyframes fadeInUp{0%{opacity:0;-o-transform:translateY(20px)}100%{opacity:1;-o-transform:translateY(0)}}@keyframes fadeInUp{0%{opacity:0;transform:translateY(20px)}100%{opacity:1;transform:translateY(0)}}.fadeInUp{-webkit-animation-name:fadeInUp;-moz-animation-name:fadeInUp;-o-animation-name:fadeInUp;animation-name:fadeInUp}
Step 3 : Add class load-animate
Now you need to add a class name load-animate where you want the animation to happen.
Example Html :
<div class="load-animate" id="inner1">
 
</div>
Step 4: Initialize the script
$(document).ready(function() {
 
&nbsp;
 
&nbsp;
 
jQuery('.load-animate').waypoint({
 
triggerOnce: true,
 
offset: '70%',
 
handler: function() {
 
jQuery(this).addClass('animated fadeInUp');
 
}
 
});
 
&nbsp;
 
});
 
JS

Glowing Circle effect CSS3 animation by keyframing

This is a simple tutorial on css3 animation.In this tutorial we are going to make a circular glow effect using css3.
HTML
<div class="ringbox">
 <div class="green gr1"></div>
<img src="images/background.png">
 </div>
CSS
.ringbox {
width: 637px;
margin: auto;
position: relative;
}
 
.green {
height: 20px;
width: 20px;
border-radius: 50%;
position: absolute;
-webkit-animation: ring 1.1s ease-out infinite;
-moz-animation: ring 1.1s ease-out infinite;
opacity: 0;
box-shadow: 0 0 1px 2px #009d7b;
}
 
.gr1 {
top: 48px;
left: 208px;
}
Ainimation CSS
@-webkit-keyframes ring{
 
0%{-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
 
50%{opacity: 1.0;}
 
100%{-webkit-transform: scale(1.2, 1.2);opacity: 0.0;}
 
}
 
@-moz-keyframes ring{
 
0%{-moz-transform: scale(0.1, 0.1);opacity: 0.0;}
 
50%{opacity: 1.0;}
 
100%{-moz-transform: scale(1.2, 1.2);opacity: 0.0;}
 
}
 
@-o-keyframes ring{
 
0%{-o-transform: scale(0.1, 0.1);opacity: 0.0;}
 
50%{opacity: 1.0;}
 
100%{-o-transform: scale(1.2, 1.2);opacity: 0.0;}

How to change the color of a placeholder of input box

Add this to your CSS to change the color of place holder.
::-webkit-input-placeholder {
   color: red;
}
 
:-moz-placeholder {
   color: red;
}
That would be nice, but the problem is that when a browser doesn’t understand a selector, it invalidates the entire line of selectors (except IE 7)
For old browsers You can use Javascript as below :
<input name="location" type="text" value="Location"
onblur="this.value=!this.value?'Location':this.value;" onclick="this.value='';" />

50 years of IBM Mainframe

Half a century since the first IBM System 360 mainframe computers were first implemented within commercial and scientific industries, we look back at the origins of the pioneering technology that defined the 20th century, and how these machines are still used today.

Founded in 1911, IBM’s most significant product came over 50 years later with the advent of the System 360 Mainframe. Built in various sizes, and designed for different purposes, these systems revolutionised sectors across the commercial and scientific markets - becoming particularly prominent in the automobile industry.

Computers were being sold prior to the invention of the System 360, however the pioneering system changed the thought process of computer manufacturing and the roles of computers in modern society.

Traces of the original 360 mainframe can be seen in legacy systems across the worldwide banking and financial sectors – which still utilise elements of the ground breaking technology today.

Whilst a number of original System 360 Mainframes still exist, they have long since ceased to function – a number are kept as visual mementos of a time that changed our world, which can be found exclusively in the US.
