background gradients in IE7 with CSS

Question

I am using the following bit of CSS to create a linear background gradient. It seems to work just fine in IE8/9, FF, Safari and chrome but not in IE7. IE7 shows a solid (green) background. Here is my code

.menu_body a {
  display:block;
  color:#006699;
  background: #008800;
  /* Mozilla: */
  background: -moz-linear-gradient(top, #0b71a4, #025f8e);
  /* Chrome, Safari:*/
  background: -webkit-gradient(linear,
            left top, left bottom, from(#0b71a4), to(#025f8e));
  /* MSIE */
  filter: progid:DXImageTransform.Microsoft.Gradient(
            StartColorStr='#0b71a4', EndColorStr='#025f8e', GradientType=0);
  padding: 1px 18px;
}

In IE<=7, filters won't work unless element has layout.

zoom: 1;

Be aware that it can break other things, so old good background-image might be safe and reliable solution.

Also please note that your CSS lacks gradient properties for Opera, IE10 and updated syntax for Webkit.
