如何使用图标和换行(！)居中显示面板文本是CSS还是JavaScript？

.container {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
}

.panel-text {
  text-align: center;
}

.container {
  position: relative;
}

.container::before {
  content: "";
  display: block;
  width: 20px; /* 图标的宽度 */
  height: 20px; /* 图标的高度 */
  background: url("icon.png") center center no-repeat; /* 图标的路径 */
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}
