css - 创建 Bootstrap 响应式布局时如何设置容器 div 的宽度？

Question

我正在尝试制作 Bootstrap 响应式布局。这里我正在尝试的是缩短主容器 div 的宽度。我尝试设置内联宽度，但布局失去了响应性。当我检查 bootstrap.css 时，容器 div 的宽度是自动的。如果有人能揭示这背后的逻辑，我将不胜感激。以下是 bootstrap 的演示代码。

PS - 我不想缩短 navbar-fixed 类的宽度，我只是想缩短容器的宽度而不失去响应能力。

HTML

Answer 1

在 bootstrap-responsive.css 文件中，您会找到代码块，称为媒体查询，例如

@media (max-width: 480px) {
  /* Your CSS here */
}

和

@media (min-width: 768px) and (max-width: 980px) {
  /* Your CSS here */
}

您可以将内容区域的宽度设置为这些 block 内每个屏幕宽度的适当宽度，而不会影响其他 block 。
