Question

我是新来的。因此，请介意我问一些愚蠢的问题，因为我刚刚开始研究HTML，CSS和BootStrap。

我正在使用Bootstrap4。如何在公司的标语行中居中？另外，如何将底部导航栏选项居中？

我已经添加了我在Bootstrap CSS文件中所做的修改，其余都是原始的。

 @import url('https://fonts.googleapis.com/css?family=Monoton');
 @import url('https://fonts.googleapis.com/css?family=Cookie');

.tag-line{
  font-family: 'Cookie', cursive;
  font-size: 1.85rem;
  color: white;
  margin-left: 10rem;
  /*float: right;*/
  /*display: inline-block;*/
  /*width: 100%;*/
}

.bg-primary {
  /*background-color: #007bff !important;*/
  background: linear-gradient(to right,#00c6ff,#0072ff);
}

.navbar-menu-config {
  text-align: center;
  font-weight: bolder;
  font-size: 1.3rem;
  float: right;
  /*text-align: center;*/
}
.navbar-brand {
  /*display: inline-block;*/
  /*padding-top: 0.3125rem;*/
  /*padding-bottom: 0.3125rem;*/
  /*margin-right: 1rem;*/
  font-size: 1.85rem;
  line-height: inherit;
  white-space: nowrap;
  font-family: 'Monoton', cursive;
  letter-spacing: 0.1rem;
  word-spacing: 0.2rem;
}
