Question

我试图仅使用HTML，CSS和Bootstrap创建响应式投资组合。导航条形码，我从w3学校得到了一些变化。导航栏后面的任何内容都没有响应。我尝试使用弹性框和媒体查询，但媒体查询选项似乎不起作用。我该如何做出响应？

.navbar{
  font-size: 1.5em;
  background-color: white;
  
  font-family: lobster;
  color: black;
}

.navbar-brand{
	font-size: 1.5em;
}

.fa{
	color: #337aa9;
}

.page-one{
	background: url("https://s20.postimg.org/otq1xf6h9/Optimized_abcd.jpg");
	font-family: lobster;
	color: #337aa9;
	height:100%;
    width: 100%;
}

.flex-container {
    display: -webkit-flex;
    display: flex;
    width: 400px;
    height: 150px;
    background-color: none;
    opacity: 0.1;
   
    }

 .cont1{
 	 margin-left: auto;
    margin-right: auto;
    padding-top: 3%
    padding-bottom:3%;
    opacity:1;
    
    color:white;
 }

.flex-item {
    background-color:none;   
    width: 100%;
    height: 100%;
    opacity:1;
}

.dp{
	height:240px;
	border-radius:50%;
}

.cont2{
	margin-left:auto;
	margin-right:auto;
}
@media screen and (max-width: 480px){
	.body{
		font-size:3px;
		font-family:arial;
	.dp{
		width:80%;

	}
}

Answer 1

终于明白了。在我将flex-container的宽度更改为100％之后，媒体查询工作。

为什么媒体查询无法正常工作？
