css - 增加引导图的高度

Question

我正在尝试将此图向下拉伸以覆盖空白区域。我已经尝试了几种选择，但到目前为止没有运气。一点帮助将不胜感激。

这是代码：

<div class="row">
                          <div class="col-lg-12 col-xl-8 offset-lg-0">
                              <div class="card shadow mb-4 h-100">
                                  <div class="card-header d-flex justify-content-between align-items-center">
                                      <h6 class="text-primary fw-bold m-0">Total Returns %&nbsp;&nbsp;</h6>
                                      <div class="dropdown no-arrow"><button class="btn btn-link btn-sm dropdown-toggle" aria-expanded="false" data-bs-toggle="dropdown" type="button"></button>
                                          <div class="dropdown-menu shadow dropdown-menu-end animated--fade-in">
