Question

注意页面如何居中。如何使其扩展以适应屏幕，包括列？对不起，我是编码的新手。我包含了大部分代码，因为我不知道在哪里可以找到它。希望你们中的一个可以提供帮助。我假设它必须在正文或主页上？

Answer 1

您必须使用百分比或使用媒体查询等内容来设置内容的特定宽度。百分比的一个例子是：

main, .header-inner, .footer-inner {
  margin: 0 auto;
  width: 90%;
}

Answer 2

更改

.side-column {
  width: 270px;
  margin-left: 45px;
}

.main-column {
  width: 620px;
 }

要

.side-column {
  width: 0px;
  margin-left: 0px;
}

.main-column {
  width: 100%;
 }

Answer 3

您的主要设置为500px宽度。您需要删除该宽度样式。然后main将占据它的父容器的整个宽度。

这背后的原理是块级元素默认占用它的父容器的整个宽度。由于main是块级元素，因此您不必设置100％;它自动默认为100％。

顺便说一下，你的主要填充样式是畸形的。你有填充：20 20px;你需要使用单位，而不仅仅是数字。所以要么写填充：20px 20px;甚至更好的只是填充：20px;

Answer 4

您似乎在CSS中使用固定大小。例如，下面的行：

.main-column {
  width: 620px;
}

.side-column {
  width: 270px;
  margin-left: 45px;
}

正在分配固定的width值。（修正后，我的意思是使用px，mm，in等单位。相反，使用相对大小（即，通常为百分比）是合适的。对于较大的包含元素，我倾向于使用vw（视口宽度）和vh（视口高度）的单位。在适当的情况下在CSS中做同样的事也应该有帮如果您选择稍后使用CSS媒体查询，这也可以更轻松地优化其他设备大小。
