Can I invert the height direction from top-down to bottom-up?

Question

I want to change the height growth path from top-down to bottom-up. Is it possible in CSS?

.button {
    margin-top:200px;
    margin-right:34px;
    width:150px;
    height:45px;
    background:black;
    float:right;
    transition-duration:2s;  
}
.buttom:hover{
    height:180px;
    transition-duration:2s;
}

<div class='button'> </div>

All you need is to set position: absolute and bottom position like this:

.buttom{
    margin-top:200px;
    margin-right:34px;
    width:150px;
    height:45px;
    background:black;
    float:right;
    position:absolute;
    bottom: 10px;
    transition: height 2s ease-in-out  
}
.buttom:hover{
    height:180px
}

                       <div class='buttom'> </div>

Use Rotate and transform-origin to be able to set position relative to the element

.buttom{
    margin-top:200px; /* this shall be higher than the height on hover*/
    margin-right:34px;
    width:150px;
    height:45px;
    background:black;
    transition: height 2s ease-in-out ;
    transform: rotatex(180deg);
    transform-origin: top;
}
.buttom:hover{
    height:180px
}
                       

<div class='buttom'> </div>

Or this way:

.buttom{
    width:150px;
    height:45px;
    background:black;
    transition: height .3s cubic-bezier(0.175, 0.885, 0.32, 1.275) ;
    transform: rotatex(180deg) translate3d(0, -200px,0);/* the Y-Value shall be higher than the height on hover*/
    transform-origin: top;
}
.buttom:hover{
    height:180px
}
    

<div class='buttom'></div>
