Question

我在让IE8遵循大小调整时遇到问题。在我的标题中，我将我的徽标设置为max-height：100％带有一些填充。应该发生的是图像的大小最终应该是标题高度的100％，减去填充量。这在现代浏览器中完美运行。但是在IE8中，图像最终是标题高度的100％，然后添加了paddding，使其从标题的边缘移开。知道为什么会这样吗？我知道IE8应该支持盒子大小。

的CSS：

    #logoimg {
  max-height:55px;
  padding:4px 10px 4px 0;
  float:left;
  border-right:1px solid #ad1d00;
  box-sizing:border-box;
}
#navigationcontainer {
  width:100%;
  background:#f1f1f1;
  -moz-box-shadow:0px 1px 3px 3px #dfdfdf;
  -webkit-box-shadow:0px 1px 3px 3px #dfdfdf;
  box-shadow:0px 1px 3px 3px #dfdfdf;
  box-sizing:border-box;
}
#navigationtopbar {
  width:100%;
  background:#ea2700;
  height:55px;
  box-sizing:border-box;
}
#navigationtopbar ul {
  float:left;
  list-style-type:none;
  padding:0;
}
#navigationtopbar ul li { float:left; }
#navigationtopbar ul li a {
  padding:0 10px 0 10px;
  line-height:55px;
  display:block;
  color:#ffffff;
  border-right:1px solid #ad1d00;
  border-left:1px solid #ef5f42;
}
#navigationtopbar ul li a:hover { background-color:#ef5f42; }
.chart {
  width:100%;
  padding:0;
  margin:0;
}

Answer 1

您的#logoimg有max-height:55px。

如果使用min / max-width / height，IE 8将忽略box-sizing: border-box。资料来源：http://caniuse.com/#search=box-sizing＆gt;已知问题＃4
