HTML元数据视口削减了我的布局。为什么会这样呢？

标签： html css

我正在构建一个响应式网页。现在，我将开始处理媒体查询，但是当我插入<meta name="viewport" content="width=device-width">并使屏幕变小时，我的页眉，第一节和页脚的背景部分被切掉，剩下的仅一部分是白色与他们的文本空间。您可以在摘要中的上看到它。为什么会发生这种情况，我该怎么办？

使用以下方法进行简单的全局重置：

html, 
body,
*,
*::before,
*::after {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

然后将主体设置为：

body {
    width: 100vw;
}

答案 1 :(得分：0)

已对您的代码进行了一些更改。最初的问题是上腹部。当中间部分的宽度大于屏幕宽度时，将出现一个水平滚动条，以允许用户查看其余内容。
要解决此问题，您可以根据屏幕的宽度将对齐方式设置为垂直而不是水平。在下面的解决方案中，我包装了内容。

第二个问题是标题中内容的宽度超过屏幕的宽度时，即容器的宽度尝试与屏幕的宽度相同时（记住meta name="viewport"），但是内容溢出（因为宽度更大）。
要解决此问题，可以在菜单内显示标题项目。在下面的解决方案中，我仅使标头（display: none）中没有空格。例如，解决方案可能类似于this。

注意：下面的解决方案没有优雅的样式，也许您可​​以在此处和此处添加填充以使其看起来优雅
