居中的模态负载微调器引导程序 4

Question

我想要一个模态负载微调器，并基于 Bootstrap 4 的模态对话框进行了测试。但是，我无法让模式在页面上水平居中。如果可能的话，我还希望模态框没有边框且透明（因此看起来只有微调器悬停在页面上）

  function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }

应用这两个类：

 .bd-example-modal-lg .modal-dialog{
    display: table;
    position: relative;
    margin: 0 auto;
    top: calc(50% - 24px);
  }

  .bd-example-modal-lg .modal-dialog .modal-content{
    background-color: transparent;
    border: none;
  }

 function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }

 .bd-example-modal-lg .modal-dialog{
    display: table;
    position: relative;
    margin: 0 auto;
    top: calc(50% - 24px);
  }

  .bd-example-modal-lg .modal-dialog .modal-content{
    background-color: transparent;
    border: none;
  }

旧帖子，我知道，但这对我来说似乎是一个更干净的选择……

 function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }
