HTML:
<a href="" class="buttons_position"><img src="images/order.png" height="49" width="214"></a>
CSS:
.buttons_position {
padding: 0 0 0 10px;
border: 0px;
margin: 0px;
}
.buttons_position a:hover {
background-image: url(images/ask_us_hover.png);
background-repeat: no-repeat;
width: 2149px;
height: 49px;
padding: 0 0 0 10px;
border: 0px;
margin: 0px;
}
但悬停图像不会改变。如何用 CSS 做到这一点?
