Bootsrapで作るシンプル　２カラム・レイアウト コードサンプル


1. 基本の２カラム


<div class="bg-light">
    <main role="main" class="container" style="padding: 0px">

  <div class="row ">
   <div class="col-md-8 bg-success"><!-- cod-8 メイン・セクション開始 -->
    <h1> <p class ='text-center'>◇Col-md-8</p></h1>
     <div class="content-section">
       <h1> <p class ='text-center'>content-section</p></h1>
     </div>
      one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three,

     <div class="content-section">
      one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three, 1,2,3,one, two, three,
     </div>
   
   </div>

   <div class="col-md-4 bg-warning">
    <ul class="list-group">
       <li class="list-group-item list-group-item-light">Latest Posts</li>
       <li class="list-group-item list-group-item-light">Announcements</li>
    </ul>
   </div><!-- col-md-4 終了-->
  </div><!-- Div row 終了-->
  </main>
 </div>










COL間にmarginは設定されていないことに注意。




・Bootstrap4 のカラム間のマージン（余白・ガター）は、paddingで指定されている。
　デフォルトでは、左右15px

.col-md-4{
    position: relative;
    min-height: 1px;
    padding-right: 15px;
    padding-left: 15px;
   }

これを変更するのは、独自のCSSでClassを作成し、適用する。

(my_gutterで挟まれたcol-md-4クラスの左右のpaddingは、7px)
.my_gutter .col-md-4 { padding: 0 7px;}



例）
<div class="row my_gutter">
 <div class="col-md-4">
sample text etc.
</div>
</div>

汎用的に、
.row-10{ margin-left:-5px;  margin-right:-5px}
.row-10 >div{ padding-right:5px;  padding-left:5px}
という書き方もできる。
