Question

我尝试从bootstrap3迁移到bootstrap4。这是非常痛苦的，在线转换器根本不起作用。

E.g。我甚至无法将以下bootstrap 3块转换为bootstrap 4

body {
  min-height: 1200px;
  padding-top: 140px;
}

.header {
/*    border-bottom: 1px solid #D8D8D8;*/
    font-family: arial;
    padding-top: 20px;
    padding-bottom: 20px;
    z-index: 100;
    background: white;
    
    position: fixed;
    top: 0;
    right: 0;
    left: 0;
}

.one-edge-shadow {
	-webkit-box-shadow: 0 8px 6px -6px black;
	   -moz-box-shadow: 0 8px 6px -6px black;
	        box-shadow: 0 8px 6px -6px black;
}

.centerText {
    text-align: center;
}

        <div class="col-lg-12 hidden-md hidden-sm hidden-xs" style="position: absolute;">
            <h3 class="centerText">Dashboard</h3>
        </div>

        <!-- Logo -->
        <div class="col-lg-11 col-lg-offset-1 hidden-sm hidden-xs">
            <img src="http://via.placeholder.com/200x100">
        </div>
        <div class="col-xs-12 hidden-lg hidden-md">
            <center><img src="http://via.placeholder.com/150x80"></center>
        </div>
    </div>
</div>

尝试：

body {
  min-height: 1200px;
  padding-top: 140px;
}

.header {
/*    border-bottom: 1px solid #D8D8D8;*/
    font-family: arial;
    padding-top: 20px;
    padding-bottom: 20px;
    z-index: 100;
    background: white;
    
    position: fixed;
    top: 0;
    right: 0;
    left: 0;
}

.one-edge-shadow {
	-webkit-box-shadow: 0 8px 6px -6px black;
	   -moz-box-shadow: 0 8px 6px -6px black;
	        box-shadow: 0 8px 6px -6px black;
}

.centerText {
    text-align: center;
}
