我有个问题真的搞不懂

当我的屏幕解决方案小于XX时，我的登录div与我的菜单重叠。（当我从21英寸改为15英寸时发现）

我看到一个菜单巫婆似乎停留在它的位置，但下面的登录框是重叠的

我不是CSS方面的天才，所以我很高兴看到人们在这里提供帮助，而且通常都非常快！
谢谢！：-）

由于您将inlogbox定位为绝对，因此它将在某个点与菜单重叠。（当窗口大小小于菜单和inlogbox的高度时）

您唯一能做的就是定位inlogbox静态

因此，改变：

#wrapper1 {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
    font-weight:300;
    text-align: left;
    text-decoration: none;
    /* Center wrapper perfectly */
    width: 300px;
    height: 400px;
    position: absolute;
    left: 50%;
    top: 50%;
    margin-left: -150px;
    margin-top: -200px;
}
致：

inlogbox将显示。如果您想在菜单和inlogbox之间留出更多空间，只需在inlogbox中添加一个
页边空白顶部
。

编辑
#包装1
，如下所示：

#wrapper1 {
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 300;
text-align: left;
text-decoration: none;
width: 300px;
height: 400px;
position: absolute;
left: 50%;
top: 145px;   /* or more  */
margin-left: -150px;
}

.gradient {
width: 600px;
height: 600px;
position: fixed;
left: 50%;
top: 145px;   /* as the top of wrapper */
margin-left: -300px;
margin-top: 0px;
background-image: url(../img/gradient.png);
background-repeat: no-repeat;
background-image: -webkit-gradient(radial, 0% 0%, 0% 100%, from(rgba(213,246,255,1)), to(rgba(213,246,255,0)));
background-image: -webkit-radial-gradient(50% 50%, 40% 40%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -moz-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -ms-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -o-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
}
你的梯度是这样的：

#wrapper1 {
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 300;
text-align: left;
text-decoration: none;
width: 300px;
height: 400px;
position: absolute;
left: 50%;
top: 145px;   /* or more  */
margin-left: -150px;
}

.gradient {
width: 600px;
height: 600px;
position: fixed;
left: 50%;
top: 145px;   /* as the top of wrapper */
margin-left: -300px;
margin-top: 0px;
background-image: url(../img/gradient.png);
background-repeat: no-repeat;
background-image: -webkit-gradient(radial, 0% 0%, 0% 100%, from(rgba(213,246,255,1)), to(rgba(213,246,255,0)));
background-image: -webkit-radial-gradient(50% 50%, 40% 40%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -moz-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -ms-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
background-image: -o-radial-gradient(50% 50%, 50% 50%, rgba(213,246,255,1), rgba(213,246,255,0));
}

更新： 作为@Atul，您也可以对
#wrapper1
使用
position:relative
。请看以下代码：

#wrapper1 {
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 300;
text-align: left;
text-decoration: none;
width: 300px;
height: 400px;
position: relative;
left: 50%;
margin-left: -150px;
}

请分享您的HTML，如果您可以创建一个您想要的登录表单，它将显示在菜单下？是的，它将显示在屏幕上，正如您可能看到的那样。：-）Wrapper1应该是相对的，并添加明确的内容：Wrapper1中的CSN和top的增量值都不好。理想情况下，wrapper1的位置应该相对清晰：两者都应该添加到wrapper1中，这很有帮助，但辉光仍然在重叠处。Statiumi没有发现Fiddle buddy中有任何问题，如果您的问题在您的网站上，只需共享链接。从侧面出来的两张图片在屏幕左侧显示为静态。
