Div重叠另一个div

标签： css

我有一个我真无法理解的问题。

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“变为15”时发现。）

我恳求一个菜单女巫似乎留在它放置的位置，但下面的登录框重叠。

我在这里得到了我的CSS：

2 个答案:

答案 0 :(得分：0)

由于您将inlogbox置于绝对位置，因此它会在某个时刻与菜单重叠。 （当窗口大小小于菜单和inlogbox的高度时）。

您唯一能做的就是将您的inlogbox静态定位。

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;
}

要：

#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;
    margin: 0 auto;
}

inlogbox将then be under the menu 。如果您想在菜单和inlogbox之间留出额外空间，只需在内容框中添加margin-top即可。

答案 1 :(得分：0)

像这样编辑#wrapper1：

#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;
}

和你的渐变一样：

.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position:relative使用#wrapper1。看看这段代码：

#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;
}
