如何将网站上的所有元素 (div) 从像素更改为百分比

Question

首先，这个网站是朋友交给我帮助建立和开发的。我已经很长时间没有碰过 CSS 了，我遇到了一些问题。我正在努力让这个网站不断适应浏览器。

我理解是因为他一直用像素来衡量类而不是百分比，所以它已经固定了。我如何着手将所有类更改为百分比，以便网页变得流畅并适合浏览器 window 如果变小。我想这将是所有数学？

我知道@media 查询不相关。

Answer 1

您需要编辑 CSS 文件。

从外面的 DIV 开始，然后逐步进入。任何你想要全宽的元素都应该 CSS 像这样：

.elementClassName{
   width: 100%
}

在HTML中，我们在标签中使用id="idnamehere"直接标注，这样我们就可以在CSS中专门针对它。我们可以使用 class="classname" 以获得更通用的 CSS ，它可以应用于许多 div。

因此您可以在 CSS 文件中添加一些 classes:

    .Fullwidth{
  width:100%
}

.halfWidth{
 width: 50%
}

然后将它们添加到外部 DIV 进行实验。

例如，如果您将 class="halfWidth" 添加到外部 DIV 并刷新浏览器，它将使整个页面只填充 window 的一半。请记住，子 div（内部）继承自父 div。
