Always put the footer at the bottom

Written byPhuoc Nguyen

Assume that our page is organized by three parts: the header, main content and footer. It's a common layout that the footer is always displayed at the bottom no matter how long the main content is.
<div class="container">
Using CSS flexbox, the layout can be implemented as following:
.container {
display: flex;
flex-direction: column;
min-height: 100vh;

footer {
flex-shrink: 0;

main {
flex-grow: 1;
Setting `flex-grow: 1` to the main content will make it take the available spaces. The footer then sticks at the bottom.
