媒体查询不起作用，而页面无响应

Question

实际上，我是HTML和CSS的新手。对于练习，我使用的是psd＆amp;试图实施，但我的媒体查询不起作用。我已经尝试将所有容器的宽度设置为100％但是当我在浏览器中执行响应模式时，右侧会出现一个空白区域。再次，当我试图减小屏幕尺寸时，它正在破碎。有人请指导我这个。这将是非常有帮助的。

Answer 1

在不同的视图端口上，根据您的要求更改.content div的宽度， 我可以给你一些断点，比如

注意： - 这只是您想法的一个示例。根据您的实际需要和设计使用

@media (max-width: 992px)  {
   .content {width: 960px;}
}
@media (max-width: 768px)  {
   .content {width: 740px;}
}
@media (max-width: 481px)  {
   .content {width: 100%;}
}

Answer 2

我已经查明了问题所在的代码。它是

.content{
    width: 1250px;
    margin: 0px auto;
}

这里指定了容器的固定宽度，因此当您缩小屏幕宽度时，它仍然具有相同的宽度。 您可以使用max-width或对其进行媒体查询。

水平滚动的另一个原因是.menu- *类的margin-left。由于窗口宽度较小，因此将内容推到画布外部，从而导致滚动。

希望这有帮助。
