两个div之间的水平线[关闭]

Question

我使用bootstrap创建了一个彩色的盒子。我想添加一条从左到右的水平线，如第二张图所示。我尝试在按钮中添加具有边框的新div，但它不适合整个框的宽度。

图：边框不适合右侧容器的图像

图：容器中预期的合身边框

这是我的代码。

.row-eq-height {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  flex-wrap: wrap;
}

我的边框不适合正确的容器。

<div class="col-md-12" style="border-bottom:1px solid red; "></div>

尝试使用!important规则将div余量和填充设置为0。
