Button animate on hover to change colors from top to bottom

Issue

What I want is the background color of a button to change from top to bottom on hover. There is a good example on this page http://tympanus.net/Development/CreativeButtons/ This is the code I have now. Thanks

CSS

#button {

    outline: 0;
    margin: 20px  10px 10px 6px;
    border-width:2.7px;
    font-size: 25px;
    border-style: solid;
    font-family: 'PT Sans Narrow', sans-serif;
    padding: 4px 40px;
    background-color: white;
    border-color: #0e83cd;
    color: #0e83cd;
    transition: all .3s ease-in;


    }

 #button:hover {
    color: white;
    background-color: #0e83cd;
    transition: all .3s ease-in;
    }

HTML

  <button id="button" />Ask</button>

Solution

there are lots of ways to do that. this css could help you.

#button {

  /*Reset*/
  display: inline-block;
  outline: none;
  background-color: transparent;

  /*Some fancy stuff*/
  padding: 0 20px;
  line-height: 200%;
  border: 1px solid silver;

  /*Magic*/
  background-image: linear-gradient(PaleVioletRed, PaleVioletRed 50%, Sienna 50%, Sienna);
  background-size: 100% 200%;
  -webkit-transition: background-position .3s;
  transition: background-position .3s;
}
#button:hover {
  background-position: 0 -100%;
}
