html - 不应用背景渐变

Question

我正在尝试让红色渐变在背景图像上起作用。有一个初始后备图像，然后附加到下一个背景图像:, linear-gradient(0deg,rgba(0,0,0,0.68),rgba(221,51,51,0.8)); - 为什么不应用渐变？

* {
  color: #000000;
  margin: 0px;
  padding: 0px;
  font-family: 'Open Sans',verdana,helvetica,arial,sans-serif;
  font-size: 100%;
  box-sizing: border-box;
}

.sadLeader {
  width: 1088px;
  height: 450px;
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
  width: 100%;

  text-align: center;
  background-repeat: no-repeat;
