How can I fix my website's footer to stay at the bottom of the page?

[LitCommerce]

Hi @ArnaudB ,

Please change code:

body{
    display: flex !important;
    flex-direction: column;
    min-height: 100vh;
}
#template-customers-login{
  flex: 1 0 auto;
}
.footer.footer--classic{
  flex-shrink: 0;
}

Hope it helps!
