Color change navbar with css transition

Question

Is there a transition that changes the color of the navigation bar every 30 seconds? Here is what I have tried so far:

.navbar {
    background-color: #080;
    -webkit-transition: background 1s;
    -moz-transition: background 1s;
    -o-transition: background 1s;
    transition: background 1s;
}

Answer 1

Using CSS3Animation, you can do this.

The following code example changes color after about 30 seconds and switches between different colors.

#navbar {
   background-color: #080;
   width: 100%;
   height: 100px;
    animation: changeColour 190s linear 2s infinite alternate;
}

@keyframes changeColour {
  0%,
  15% {
background-color: #080;
  }
  16%,
  30% {
background-color: #F98A01;
  }
  31%,
  45% {
background-color: #C61F83;
  }
  46%,
  60% {
background-color: #DE9914;
  }
  61%,
  75% {
background-color: #1EB6DC;
  }
  76%,
  90% {
background-color: #0060A1;
  }
  91%,
  100% {
background-color: #080;
  }
}

<div id="navbar"></div>

Use this timeout:

$(elem).css('z-index','0');
setTimeout(function(){ $(elem).css('z-index','2'); },2000)

. :

.navbar {
    -webkit-animation-name: changeColorAnim;
    animation-name: changeColorAnim;
    -webkit-animation-duration: 90s;
    animation-duration: 90s;
    animation-iteration-count: infinite;
}

@-webkit-keyframes changeColorAnim {
    0% { background-color: black }
    50% { background-color: white }
    100% { background-color: black }
}

@keyframes changeColorAnim {
    0% { background-color: black }
    50% { background-color: white }
