div element will not move to bottom of the page-CodePudding

I'm trying to make a JavaScript piano, with the keys being at the bottom of the screen, but setting bottom: 0px; doesn't work

html {
  height: 100%;
  width: 100%;
  position: relative;
}


/*keyboard div*/

#keyboard {
  position: relative;
  display: table;
  width: 1366px;
  height: 90px;
  bottom: 0px;
}


/*keys, if those are important*/

#wk,
#bk {
  display: table-cell;
  border-color: #000000;
  border-width: 1px;
  border-style: solid;
}

#wk {
  position: relative;
  height: 90px;
  width: 1.92%;
  background-color: #ffffff;
}

#bk {
  z-index: 1;
  position: absolute;
  height: 52px;
  width: 58.05%;
  right: -9.04px;
  background-color: #000000;
}

<html>
<div id="keyboard">
  <div id='wk'>
    <div id='bk'></div>
  </div>

  <div id='wk' class=''>
  </div>
</div>

Replace your styles as given below:

#keyboard {
    height: 90px;
    position: fixed;
    bottom: 0;
    width: 100%;
    background-color:#0000FF;
}

/*keys, if those are important*/
#wk, #bk {
    border-color:#000000;
    border-width: 1px;
    border-style: solid;
}

#wk {
    height:90px;
    width: 1.92%;
    background-color: #ffffff;
}
#bk {

    height:52px;
    width: 58.05%;
    right: -9.04px;
    background-color: #000000;
}

Dont set bottom since that will move it from down to up rather set: top: 50%;

but since your width and height are odd use 41% to place it nicely

also its a nice practice to use em/rem or simply % and not px
