如何在模态中居中行？

Question

我正在使用bootstrap 3，我无法将项目放在里面，我在这里插入了我的代码，但它看起来不像网站。

$('#modall').modal('show');

  .fr-popup-btn-margin-left{
  margin-left:1.7vw !important;
}
.fr-title-popup-margin{
  margin-top:20px;
}
.fr-popup-btns{
  text-align:center;
}
.fr-popup-title{
  font-size:24px;
  font-family: 'Montserrat', sans-serif;
  color: #008cc0;
  font-weight: 800;
  text-align: center;
}
.modal-fr-btn{
    border-radius: 40px;
    height: 25px;
    width: 80px;
    font-size: 14px;
    font-family: 'Montserrat', sans-serif;
    color: white;
    font-weight: 800;
    padding: 0;
}
.dont{
    font-family: 'Montserrat', sans-serif;
    font-weight: 400;
    font-size:10px;
}

.first-row-popup {
  padding: 0 !important;
  margin-top:0px;
  margin-right:0px;
  margin-left:0px;
  margin-bottom:10px;

}
@media (min-width: 992px){
    .pop2{
        width:25vw;
    }
        .pop1{
          width:30%;
    }
}

                                    width="54">
                            </a>
                        </div>
                        <div class="row nopadding">
                            <a class="dont close-fr-popup col-xs-6" href="">English</a>
                        </div>
                    </div>
                </div>

            </div>
        </div>
    </div>

请注意，在网站上，标志不在模态的中间，它们稍微向左。我不想添加填充或边距。

除了我上面尝试的，我还尝试了text-center行和text-align: center和margin: 0 auto。什么都行不通，似乎有些事情是在左边添加填充比右边更多。
