关于实现两列居中布局及多屏幕响应式适配的技术求助

我看了你的代码和需求，发现当前布局的核心问题在于没有充分利用Flex布局实现真正的居中，以及缺少针对小屏幕的响应式规则。下面是调整后的完整代码，同时我会拆解关键改动点：

关键改动说明 #

• 重构了列表容器的布局，使用Flex实现水平居中+自动换行，适配不同屏幕宽度
• 优化了每个图标项的内部结构，确保图标和文字垂直对齐
• 调整Bootstrap列的响应式规则，小屏幕下单栏显示，中等及以上屏幕双栏
• 优化了文字区域的样式，确保小屏幕下文字不会溢出，自动调整布局

          <div class="cchart">
            <b>WEBCAMS</b>
            <div>Hold Visual Meetings</div>
          </div>
        </li>
      </ul>
    </div>
  </div>
  <!-- 右侧列同样调整响应式 -->
  <div class="col-12 col-md-6" style="background: #F99B10; min-height:926px">
  </div>
</div>

这样调整后，布局会在所有屏幕尺寸下保持居中，小屏幕时图标项会自动换行，不会出现挤在一起的情况，同时每个图标和文字的对齐也更加规整。
