html - 防止 div 内的图标折叠到其他 div 内

Question

因此，使用 HTML、CSS 和 Bootstrap，我在包装器的左侧有 4 个图标，它们的组织类似于正方形。但是当我调整窗口大小时，这些图标会在我下面的控制台后面折叠。我怎样才能防止这种情况发生（将按钮保持在同一位置会很好）？

这是 CSS 和 HTML 的代码

#designContainer {
  display: none;
  background-color: #fff;
  position: absolute;
  bottom: 40px;
  top: 120px;
  left: 10%;
  /*width of toolbar*/
  margin-left: 38px;
  /*margin of toolbar*/
  right: 20px;
  overflow: hidden;
  border: 1px solid #003399;
  /* border-top:3px solid #FFCC00; */
  z-index: 10;
  cursor: crosshair;
}

#toolsWrapper {
  display: none;
  background-color: #fff;
  position: absolute;
  bottom: 40px;
  top: 120px;
  left: 20px;
  width: 10%;
  overflow: hidden;
  z-index: 11;
  margin-bottom: 0;
}

#toolsWrapper label img {
