Answer 1

You could use the vh unit to do this.

 body, html { height: 1000px; margin: 0; } div { position: relative; width: 100px; height: 100px; background: tan; top: calc(100vh - 100px); } 

 <div></div> 

Answer 2

Try adding this css to your id or class:

div {   
position: absolute; 
bottom: 0; 
}
