Question

我在twitter Bootstrap中使用绝对定位的导航栏，但是当我使用导航栏项目在我的标签内部使用.pull-right类时，导航栏项目保持在左侧。我也尝试过使用float：right;和text-align：对;那些没用。导航栏的绝对定位是否会影响此行为？如何让导航栏项目转到横幅的右侧？

.wrapper {
  position: relative;
}

#banner {
  height: 50vh;
  width: 100vw;
  position: relative;
}

#responsive-nav {
  background-color: transparent;
  position: absolute;
  z-index: 2;
}

#logo {
  position: absolute;
  top: 15px;
  left: 60px;
  z-index: 1;
}

id =“responsive-nav”的父div必须是宽度100％

Answer 3

将width: 100%添加到#responive-nav。

  #responsive-nav {
  background-color: transparent;
  position: absolute;
  z-index: 2;
  width: 100%;}
