Question

我被困在第一个个人项目中。我一直在尝试几个小时，以使Bootstrap 4导航栏固定在顶部居中的位置（最大宽度为970px）。直到包括固定顶部在内，一切都运转良好，我提出了所有建议，但没有运气。我尝试将主体填充50px，将导航栏封闭在容器中。这是我的代码

  body {
  background: #eeeeee;
  font-family: 'Varela Round', sans-serif;
  padding-top: 50px;
}

.content {
  background-color: #fff;
  max-width: 970px;
  margin: 0 auto;
}

.form-inline {
  display: inline-block;
}

.navbar-header.col {
  padding: 0 !important;
}

.navbar {
  background: #fff;
  padding-left: 16px;
  padding-right: 16px;
  border-bottom: 1px solid #d6d6d6;
  box-shadow: 0 0 4px rgba(0, 0, 0, .1);
}

.nav-link img {
  border-radius: 50%;
  width: 36px;
  height: 36px;
  margin: -8px 0;
  float: left;
  margin-right: 10px;
}

.navbar .navbar-brand {
  color: #555;
  padding-left: 0;
  font-size: 20px;
  padding-right: 50px;
  font-family: 'Raleway', sans-serif;
}

.navbar .navbar-brand b {
  font-weight: bold;
  color: #eb5844;
}

.navbar ul.nav li a:hover,
.navbar ul.nav li a:focus {
  color: #f08373 !important;
}

.navbar ul.nav li.active a,
.navbar ul.nav li.active a:hover,
.navbar ul.nav li.active a:focus {
  color: #eb5844 !important;
  background: transparent !important;
}

.search-box {
  position: relative;

似乎您要做的就是将导航栏后面的内容包装在.container

中

body {
  background: #eeeeee;
  font-family: 'Varela Round', sans-serif;
  padding-top: 50px;
}

.content {
  background-color: #fff;
  max-width: 970px;
  margin: 0 auto;
}

.form-inline {
  display: inline-block;
}

.navbar-header.col {
  padding: 0 !important;
}

.navbar {
  background: #fff;
  padding-left: 16px;
  padding-right: 16px;
  border-bottom: 1px solid #d6d6d6;
  box-shadow: 0 0 4px rgba(0, 0, 0, .1);
}

.nav-link img {
  border-radius: 50%;
  width: 36px;
  height: 36px;
  margin: -8px 0;
  float: left;
  margin-right: 10px;
}

.navbar .navbar-brand {
  color: #555;
  padding-left: 0;
  font-size: 20px;
  padding-right: 50px;
  font-family: 'Raleway', sans-serif;
}

.navbar .navbar-brand b {
  font-weight: bold;
  color: #eb5844;
}

.navbar ul.nav li a:hover,
.navbar ul.nav li a:focus {
  color: #f08373 !important;
}

.navbar ul.nav li.active a,
.navbar ul.nav li.active a:hover,
.navbar ul.nav li.active a:focus {
  color: #eb5844 !important;
  background: transparent !important;
}

.search-box {
  position: relative;
}
