Question

好的，所以此刻我正在忙着学习响应式CSS。这对你来说可能很简单，但我不明白如何实现这个目标：

我正在玩'网格'。我已将所有类设置为宽度和高度的百分比，因此这不应该是问题。但是，当我调整视口（窗口）的大小时，它不会动态增长或缩小。

请参阅：here

目前使用以下html：

<meta name="viewport" content="width=device-width" /> 

<div id="wrapper">
<div id="header">
<a href="" title="FavoriteFM" class="top-logo-container"></a>
</div>
<div id="presenter">
<a href="" title="FavoriteFM" class="presenter-one"></a>
<a href="" title="FavoriteFM" class="presenter-two"></a>
<a href="" title="FavoriteFM" class="presenter-three"></a>
<a href="" title="FavoriteFM" class="presenter-four"></a>
<a href="" title="FavoriteFM" class="presenter-five"></a>

</div>

<div id="main">


</div>

使用以下CSS：

<style>

/* Theme  */
html {
margin-top: 0px !important;
}

/* DO NOT EDIT OR MONKEYS WILL BITE YOU */
.frame_holder {
position: absolute;
top: 8px;
bottom: 50px;
/* left: 50px; */
right: 150px;
background: #ffffff;
}

.my_frame {
width: 149%;
height: 108%;
/* border: 1px solid #e0e0e0; */
}

body {
    background-color: #f0ede9;
    margin-top: 0px;
    position: relative;
    background-repeat: no-repeat;
    -webkit-background-size: cover;

Answer 1

您错过了关闭@media screen and (max-width: 965px)并在此断点中将#wrapper设置为width: 100%;。然后它会响应。

@media screen and (max-width: 965px) {
    body {
        width: 50%;
    }

    #wrapper {
        width: 100%;
    }

    #main {
        width: 50%
    }
}

此外：我觉得将body和#main的宽度设置为50％是不合理的。
