animate.css

Dynamically add animations using jQuery with ease:

$('#yourElement').addClass('animated bounceOutLeft');

You can also detect when an animation ends:

$('#yourElement').one('webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend', doSomething);

You can change the duration of your animations, add a delay or change the number of times that it plays:

#yourElement {
  -vendor-animation-duration: 3s;
  -vendor-animation-delay: 2s;
  -vendor-animation-iteration-count: infinite;
}

CSS3 Animations

An animation lets an element gradually change from one style to another.

/* The animation code */
@keyframes example {
    from {background-color: red;}
    to {background-color: yellow;}
}

/* The element to apply the animation to */
div {
    width: 100px;
    height: 100px;
    background-color: red;
    animation-name: example;
    animation-duration: 4s;
}
/* The animation code */
@keyframes example {
    0%   {background-color: red;}
    25%  {background-color: yellow;}
    50%  {background-color: blue;}
    100% {background-color: green;}
}
/* The animation code */
@keyframes example {
    0%   {background-color: red; left:0px; top:0px;}
    25%  {background-color: yellow; left:200px; top:0px;}
    50%  {background-color: blue; left:200px; top:200px;}
    75%  {background-color: green; left:0px; top:200px;}
    100% {background-color: red; left:0px; top:0px;}
}

Delay an Animation

div {
    width: 100px;
    height: 100px;
    position: relative;
    background-color: red;
    animation-name: example;
    animation-duration: 4s;
    animation-delay: 2s;
}

Set How Many Times an Animation Should Run

div {
    width: 100px;
    height: 100px;
    position: relative;
    background-color: red;
    animation-name: example;
    animation-duration: 4s;
    animation-iteration-count: 3;
}

use the value “infinite” to make the animation continue for ever

Run Animation in Reverse Direction or Alternate Cycles

div {
    width: 100px;
    height: 100px;
    position: relative;
    background-color: red;
    animation-name: example;
    animation-duration: 4s;
    animation-iteration-count: 3;
    animation-direction: reverse;
}
div {
    width: 100px;
    height: 100px;
    position: relative;
    background-color: red;
    animation-name: example;
    animation-duration: 4s;
    animation-iteration-count: 3;
    animation-direction: alternate;
}

Specify the Speed Curve of the Animation

#div1 {animation-timing-function: linear;}
#div2 {animation-timing-function: ease;}
#div3 {animation-timing-function: ease-in;}
#div4 {animation-timing-function: ease-out;}
#div5 {animation-timing-function: ease-in-out;}

CSS3 Transitions

CSS3 transitions allows you to change property values smoothly (from one value to another), over a given duration.

div {
    width: 100px;
    height: 100px;
    background: red;
    -webkit-transition: width 2s; /* For Safari 3.1 to 6.0 */
    transition: width 2s;
}
div:hover {
    width: 300px;
}

Change Several Property Values

div {
    -webkit-transition: width 2s, height 4s; /* Safari */
    transition: width 2s, height 4s;
}

Specify the Speed Curve of the Transition

#div1 {transition-timing-function: linear;}
#div2 {transition-timing-function: ease;}
#div3 {transition-timing-function: ease-in;}
#div4 {transition-timing-function: ease-out;}
#div5 {transition-timing-function: ease-in-out;}

Delay the Transition Effect

div {
    -webkit-transition-delay: 1s; /* Safari */
    transition-delay: 1s;
}

Transition + Transformation

div {
    -webkit-transition: width 2s, height 2s, -webkit-transform 2s; /* Safari */
    transition: width 2s, height 2s, transform 2s;
}

CSS3 2D Transforms

translate()
The translate() method moves an element from its current position (according to the parameters given for the X-axis and the Y-axis).

div {
    -ms-transform: translate(50px, 100px); /* IE 9 */
    -webkit-transform: translate(50px, 100px); /* Safari */
    transform: translate(50px, 100px);
}

rotate()
The rotate() method rotates an element clockwise or counter-clockwise according to a given degree.

div {
    -ms-transform: rotate(20deg); /* IE 9 */
    -webkit-transform: rotate(20deg); /* Safari */
    transform: rotate(20deg);
}

scale()
The scale() method increases or decreases the size of an element (according to the parameters given for the width and height).

div {
    -ms-transform: scale(2, 3); /* IE 9 */
    -webkit-transform: scale(2, 3); /* Safari */
    transform: scale(2, 3);
}

skewX()
The skewX() method skews an element along the X-axis by the given angle.

div {
    -ms-transform: skewX(20deg); /* IE 9 */
    -webkit-transform: skewX(20deg); /* Safari */
    transform: skewX(20deg);
}

skewY()
skew()
matrix()
The matrix() method combines all the 2D transform methods into one.

CSS media Query

if screen width is less than 768px use this custom style:

#loginBody {
  width: 600px;
  height: 400px;
  margin-top: 100px;
  border-radius: 25px;
  background: rgb(238, 238, 238);
  background: -moz-linear-gradient(left, rgba(238, 238, 238, 1) 0%, #f8f8f8 100%);
  background: -webkit-linear-gradient(left, rgba(238, 238, 238, 1) 0%, #f8f8f8 100%);
  background: linear-gradient(to right, rgba(238, 238, 238, 1) 0%, #f8f8f8 100%);

  @media screen and (max-width: 768px) {
    width: 300px;
    height: 300px;
  }
}

How to overlay one div over another div in HTML

use position: relative on the parent and child element with position: absolute.

<div id="container">
  <div id="navi">a</div>
  <div id="infoi">
    <img src="https://appharbor.com/assets/images/stackoverflow-logo.png" height="20" width="32" />b
  </div>
</div
#container {
  width: 100px;
  height: 100px;
  position: relative;
}
#navi,
#infoi {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
}
#infoi {
  z-index: 10;
}
