css – 如何在创建引导响应布局时将宽度设置为容器div？

我正在尝试制作一个自举响应式布局.这里我想要的是缩短主容器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的宽度是自动给定的.如果有人能透露这背后的逻辑,我真的很感激.以下是bootstrap的演示代码.

PS – 我不想缩短导航栏固定类的宽度,我只是想缩短容器的宽度而不会失去响应能力.

解决方法

在bootstrap-responsive.css文件中,您将找到代码块,称为媒体查询,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块内每个屏幕宽度的适当宽度,而不会影响其他块.
