adjusting background color gradient of a submit button with css

Question

Hi i want to style an input submit button which has a background as given in the attached image.The back ground image was provided, but im not sure how to implement it in the submit button so instead of using that image i tried using the css 3 color gradient properties to style the button,however, i cant get the desired color output.Any help is welcome.

CSS code so far.

.button {
  -moz-border-radius: 18px;
  -moz-box-shadow: #fffff 0px 0px 11px;
  -webkit-border-radius: 18px;
  -webkit-box-shadow: #6E7849 0 0 10px;
  background-color: #fefefefe;
  background-image: -moz-linear-gradient(24deg, #d8d8d8, #fefefefe);
  background-image: -ms-linear-gradient(24deg, #d8d8d8, #fefefefe);
  background-image: -o-linear-gradient(24deg, #d8d8d8, #fefefefe);
  background-image: -webkit-linear-gradient(24deg, #d8d8d8, #fefefefe);
  background-image: linear-gradient(24deg, #d8d8d8, #fefefefe);
  border-radius: 18px;
  border: 1px solid #888888;
  box-shadow: #fffff 0px 0px 11px;
  color: #000000;
  display: inline-block;
  font-size: 3em;
  margin: auto;
  padding: 4px;
  text-decoration: none;
}

Answer 1

Use the image. Matching the gradient fully to the image is an unnecessary pain:

.button {
   display:block;
   width:50px; //use actual image width
   height:50px; // use actual image height
   background:url(../img/button.png); //image file path
}

.button:hover {
 background:url(../img/button_hover.png); 
 }

要将图像用作输入非常简单：

<input type="image"src="/images/submit.gif" />

Finally i found the way to make this button using sliding door technique.However still in jeopardy to style it in disabled state. This link helped me alot http://www.springload.co.nz/love-the-web/dynamic-submit-buttons

css

div.submit_button { 
   background: transparent url('common/images/bg-submit2.png') no-repeat 0 0; 
   display: block; 
   float: left; 
   height: 27px; /* total height of the button */ 
   padding-left: 15px; /* end width */ 
} 

span.submit_button_end { 
   background: #fff url('common/images/bg-submit2.png') no-repeat 100% 0; /*  used a sprite image */ 
   display: block; 
   float: left; 
   font-weight: normal; 
   height: 27px; /* total height of the button */ 
} 

input.submit_input { 
   font-size: 13px; 
   font-weight:bold;
   background: none; 
   border: none; 
   padding: 0 0 2px 15px; /* end width */ 
   color: #1b1d60; 
   cursor: pointer; 
   position: relative; 
   height: 25px; 
   line-height: 25px; 
   left: -15px;  
   margin-right: -15px; 
   padding-right: 15px; 
} 

input.submit_input:hover {color: #fff;} 

div.submit_button:hover {background-position: 0 100%;} 

div.submit_button:hover span.submit_button_end {background-position: 100% 100%;} 

HTML

 <div class='submit_button'> 
   <span class='submit_button_end'> 
     <input class='submit_input' type='submit'  value='Submit button' tabindex='#' /> 
   </span> 
</div>
