CSS: fixed to bottom and centered

Question

I need my footer to be fixed to the bottom of the page and to center it. The contents of the footer may change at all time so I can\'t just center it via margin-left: xxpx;

Answer 1

here is an example using css grid.

html, body{
    height: 100%;
    width: 100%;
}
.container{
    height: 100%;
    display:grid;
    /*we divide the page into 3 parts*/
    grid-template-rows: 20px auto  30px;
    text-align: center;   /*this is to center the element*/ 
    
}

.container .footer{
    grid-row: 3;   /*the footer will occupy the last row*/
    display: inline-block;
    margin-top: -20px;
}
