在列中打破UL（为清晰起见编辑）

Question

我的第一堂课在我的页面上有以下代码。

<div class="home-tab-title">
<img class="home-duck" src="https://accenturelife-
prod.mindtouch.us/@api/deki/files/2426/AlipSuite.png?origin=mt-web" />
<div class="home-heading">'Training Documentation'</div>
</div>

<div class="tab-content1">

</ul>
</div>

为此课程提供以下css：

.home-tab-title {
 width: 100%;
 height: 65px;
 padding: 10px 0 10px 0;
 }

 img.home-duck{
 width: 35px;
 float: left;
 padding: 12px 10px 0 0;
 }

 .home-heading {
 display:block;
 float: left;
font-size: 22px;
margin-top: 20px;
margin-bottom: 20px;
clear: right;
font-family: "Segoe UI", arial, sans-serif;
}

.home-subheading {
 margin-top:10px;
 margin-bottom:10px;
 }

.home-subheading{
font-size:15px;
color: #000;
font-weight: 500;
font-family: "Segoe UI", arial, sans-serif;;
display: inline-flex;
}

.tab-content1 {
margin-left: 2.2em;
display: inline-flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: left;
min-width: 40px;
}

.tab-content1-block {padding: 0 5em 1em .5em;}
.tab-content1-block ul li {margin-bottom:10px; margin-left:-22px;}

输出显示如下：

我有第二堂课，有大量的学生。我想把它分成三列，并希望它们完全对齐在第一列的uls下面。

 <div class="tab-content1-block1">
 <div class="home-subheading">'Business Configurator Training'</div>
 <ul style="list-style: none;">
 <li><a href="/@api/deki/files/3170/BC_Exercise.zip?origin=mt-web">'BC

<li><a href="/03_Training/Onshore_Training_Approach_-_Business">'Onshore   
 Training Approach - Business Configurator'</a></li>
</ul>
</div>

此类的CSS代码如下

 .tab-content1-block1 {padding: 0 5em 1em 5em;}
 .tab-content1-block1 ul li {margin-bottom:10px; margin-left:-22px;}

 .tab-content1-block1 ul 
 {
 -moz-column-count: 3;
 -moz-column-gap: 20px;
 -webkit-column-count: 3;
 -webkit-column-gap: 20px;
  column-count: 3;
  column-gap: 20px;
  }

输出如下。对齐似乎不合适。它应该正好在第一个图中的列之下。

有人可以帮忙解决这个问题吗？任何帮助都会受到赞赏吗？
