我想不通..希望其他人可以.

我有一个图像按钮.悬停效果很好.但是，我在按钮图像上显示了 IE 损坏的图像图标.

看这里:时髦图片 Funky Image Hover

如您所见......它们都可以工作，除了那个烦人的破碎图像.

这是我的 CSS:

这仅仅意味着你在 source 属性中引用了一个不存在的图像.您应该考虑改用实际的 <button> 标签.它只需要一些额外的样式属性来移除边框和填充:

.donate-btn{背景:透明 url(/custom/img/donate-btn.png) 0 0 不重复；溢出:隐藏；高度:45px；宽度:210px；边框:无；填充:0；向左飘浮;}.donate-btn:悬停{背景位置:0 -45px；}

我还通过删除悬停状态下的一些不必要的样式来简化您的 CSS.

<button class="donate-btn" type="submit"></button>

I can't figure this out..hopefully someone else can.

I have an image button . The hover effect works fine. However, I have the IE broken image icon over the button image.

Lookie here: Funky Image Funky Image Hover

As you can see...they both work except for that annoying broken image.

Here's my CSS:

.donate-btn{
background: transparent url(/custom/img/donate-btn.png) no-repeat;
overflow:hidden;
height:45px;
width:210px;
float:left;
}
.donate-btn:hover{
background: transparent url(/custom/img/donate-btn.png) no-repeat;
height:45px;
width:210px;
background-position: 0 -45px;
}

This simply means you are referencing a non-existent image in the source attribute. You should consider using the actual <button> tag instead. It just needs a few extra style attributes to remove borders and padding:

.donate-btn{
    background: transparent url(/custom/img/donate-btn.png) 0 0 no-repeat;
    overflow:hidden;
    height:45px;
    width:210px;
    border: none;
    padding: 0;
    float:left;
}

.donate-btn:hover{
    background-position: 0 -45px;
}

I also simplied your CSS by removing some unnecessary styling in the hover state.

<button class="donate-btn" type="submit"></button>
