logo标签列表

导航栏位置4

即使我已经指定了navbar-right，Logo和li也更靠近中心。在我的13英寸Mac上看起来不错，但在办公室的PC上却看起来不同。而且图片并非真正响应式，.img-responsive没有任何作用。

.navbar {
   min-height: 80px;
   margin-bottom: 0;
}
#btnnavbar {
   margin-top: 20px;
}

#btnhome {
   margin-top: 16px;
}

#imgbrand {
   margin-top: -70px;
   margin-left: px;
   height: 220px;
   width: 280px;
}

#firstpage {
   margin-top: 90px;
}

.button {
   color: blue;
}

我认为用<div class="container-fluid">替换<div class="container">可以解决这个问题。而你没有指定#imgbrand的margin-left值。 - Banzay
@Banzay 谢谢！问题已修复！ - Edgar Kiljak
我把一个评论放置为答案，请投票支持。 - Banzay
还有，您能告诉我如何更改导航栏中按钮的颜色和悬停背景颜色吗？我已经尝试了所有类和ID选择器，但似乎没有任何作用。 - Edgar Kiljak

将导航栏内的"class container"更改为"container-fluid"，如Banzay所说。 

.navbar {
  min-height: 80px;
  margin-bottom: 0;
}
#btnnavbar {
  margin-top: 20px;
}
#btnhome {
  margin-top: 16px;
}
#imgbrand {
  margin-top: -70px;
  margin-left: px;
  height: 220px;
  width: 280px;
}
#firstpage {
  margin-top: 90px;
}
.button {
  color: blue;
}
