html - 如何使div向上切换

Question

我正在制作一个迷你菜单，我已经使用 Bootstrap 切换来制作它。我想要的是迷你菜单应该向上而不是向下切换。我已经发布了我的代码。如果这可以用不同的方法实现，请告诉。

.mini-menu
{
  position: absolute;
  background-color: white;
  border: 1px solid lightgrey;
  padding-top: 15px;
  padding-left: 15px;
  padding-right: 15px;
  padding-bottom: 15px;
  margin-left: -200px;
  width: 200px;
}

.button-carrier
{
  position: fixed;
  top: 85%;
  left: 75%;
}
.button-round {
  border: none;
  cursor: pointer;
  color: white;
  width: 60px;
  height: 60px;
  border-radius: 50%;
  font-size: 22px;
  box-shadow: 2px 2px 4px rgba(0, 0, 0, .4);
  background: #2196F3;
}

.button-round {
  position: relative;
  overflow: hidden;
}

.button-round:after {
  content: '';
  position: absolute;
  top: 50%;
  left: 50%;
  width: 5px;
  height: 5px;
  background: rgba(255, 255, 255, .5);
  opacity: 0;
  border-radius: 100%;
  transform: scale(1, 1) translate(-50%);
  transform-origin: 50% 50%;
}

@keyframes ripple {
  0% {
    transform: scale(0, 0);
    opacity: 1;
  }
  20% {
    transform: scale(25, 25);
    opacity: 1;
  }
  100% {
    opacity: 0;
    transform: scale(40, 40);
  }
}

.button-round:focus:not(:active)::after {
  animation: ripple 1s ease-out;
}

可能您想要这样的东西。

.mini-menu {
  right: 100%;
  width: 200px;
  bottom: 0;
  position: absolute;
}

.mini-menu.collapsing {
  position: absolute;
}

.mini-menu .inner {
  padding-top: 15px;
  padding-left: 15px;
  padding-right: 15px;
  padding-bottom: 15px;
  background-color: white;
  border: 1px solid lightgrey;
}

.button-carrier {
  position: fixed;
  bottom: 15%;
  left: 75%;
}

.button-round {
  border: none;
  cursor: pointer;
  color: white;
  width: 60px;
  height: 60px;
  border-radius: 50%;
  font-size: 22px;
  box-shadow: 2px 2px 4px rgba(0, 0, 0, .4);
  background: #2196F3;
}

.button-round {
  position: relative;
  overflow: hidden;
}

.button-round:after {
  content: '';
  position: absolute;
  top: 50%;
  left: 50%;
  width: 5px;
  height: 5px;
  background: rgba(255, 255, 255, .5);
  opacity: 0;
  border-radius: 100%;
  transform: scale(1, 1) translate(-50%);
  transform-origin: 50% 50%;
}

@keyframes ripple {
  0% {
    transform: scale(0, 0);
    opacity: 1;
  }
  20% {
    transform: scale(25, 25);
    opacity: 1;
  }
  100% {
    opacity: 0;
    transform: scale(40, 40);
  }
}

.button-round:focus:not(:active)::after {
  animation: ripple 1s ease-out;
}
