我讨厌发布如此简单的代码,但正如你所看到的,我通过在div之间放置html注释来消除相关元素之间的空白。
我还确保没有任何相关元素的边距,但是,我仍然在IE和Firefox中看到这一点(如果它只是IE,我可以使用条件注释来解决这个问题):
在Chrome中,我看到它,因为我希望所有浏览器都能呈现它(就像往常一样,只有Chrome才能正确使用它):
这个白色空间来自哪里?我可以做些什么来摆脱它,跨浏览器? (如果相关,我还必须遵守IE8。)
答案 0 :(得分:1)
这可能是因为您的图片使用了默认的display: inline
属性,该属性将行高应用于图像,通常会在图像底部产生一些空格。
尝试将display: block
添加到.DDL img
:
.DDL img
{
position: absolute;
top: 0;
width: 100%;
height: 100%;
z-index: 1;
display: block;
}
答案 1 :(得分:0)
出于某种原因,#btnWrapper
div被迫拥有比IE和FF中更高的行高。添加(最多).7em的行高证明了关闭空白区域(有点搞笑,因为实际的按钮本身(包含在#btnWrapper
div中)的行高为1.3em ,所以这对我来说没有任何意义,但......)。
所以简而言之,我只是将所述属性添加到#btnWrapper
规则中,如下所示:
#btnWrapper
{
white-space: nowrap;
overflow: hidden;
margin: 0px;
line-height: .7em;
}
