我如何使用css选择器仅将样式赋予同一类型的两个div之间的第一个div？

I want to give border to the first div with the class block in the code below:

我想在下面的代码中使用类块给第一个div边框：

<div class="col-md-4 news">
            <h3>News Feed</h3>
            <div class="block">
              <p class="date"><span>15</span>march</p>
              <p><a href="#">serving people from 23 branches all over the nepal</a></p>
              <div class="clearfix"></div>
            </div>
            <div class="block">
              <p class="date"><span>17</span>march</p>
              <p><a href="#">serving people from 23 branches all over the nepal</a></p>
              <div class="clearfix"></div>
            </div>
          </div>
