http://tylerh.info,我有一个固定的导航栏。但每当我使用属性“position:fixed;”它在它下面留下了一小块空间,导致我的标题不与它接壤。但是,取出该属性不会发生这种情况。
谢谢!

您网站上的css和html存在一些问题。
<h6>
。我没有看到用途
为了这。这也是你的标题被推倒的原因。尝试删除它。那应该可以解决你的问题。无论如何,在Chrome代码检查器中为我工作。
也许您可以尝试在W3C网站上验证您的css和html,因为它可能存在更多问题。

将div#header
条目替换为(已添加padding-top:60px
):
div#header {
width: 100%;
margin-bottom: 20px;
padding-top: 1px;
/*gradients */
background-image: -ms-radial-gradient(center, circle farthest-corner, #006AD4 0%, #2500A1 100%);
background-image: -moz-radial-gradient(center, circle farthest-corner, #006AD4 0%, #2500A1 100%);
background-image: -o-radial-gradient(center, circle farthest-corner, #006AD4 0%, #2500A1 100%);
background-image: -webkit-gradient(radial, center center, 0, center center, 506, color-stop(0, #006AD4), color-stop(1, #2500A1));
background-image: -webkit-radial-gradient(center, circle farthest-corner, #006AD4 0%, #2500A1 100%);
background-image: radial-gradient(circle farthest-corner at center, #006AD4 0%, #2500A1 100%);
/*end gradients*/
border-bottom: solid 2px #808080;
padding-top:60px;
}
和您的#qm0
条目(已删除margin-top:-4.7em
):
#qm0 {
background-image: linear-gradient(bottom, #363636 19%, #1A1A1A 53%, #000000 80%);
background-image: -o-linear-gradient(bottom, #363636 19%, #1A1A1A 53%, #000000 80%);
background-image: -moz-linear-gradient(bottom, #363636 19%, #1A1A1A 53%, #000000 80%);
background-image: -webkit-linear-gradient(bottom, #363636 19%, #1A1A1A 53%, #000000 80%);
background-image: -ms-linear-gradient(bottom, #363636 19%, #1A1A1A 53%, #000000 80%);
padding-bottom: 4.5px;
position:fixed;
border-color:#A2BFE9;
position:fixed;
width: 100%;
height: 50px;
border-bottom: 1px solid #00A3EF;
}
并从<h6></h6>
上方的HTML中删除<ul id="qm0" class="qmmc">
。

我遇到了同样的问题。将position:fixed
应用于元素后,8px
的边距以某种方式应用于父元素,因此我将父元素设置为margin:0
,并将其解析。(Chrome)
这是示例
<body style="margin:0"><!-- the parent element -->
<div style="position:fixed:background-color:grey;width:100%">
Hello World
</div>
</body>
使用margin:8px
position:fixed
