CSS - Sticky footer [duplicate]

Answer 1

With Flexbox, life is way easier.

.FlexContainer {
  display: flex;
  flex-direction: column;
}

.Main-Content {
  flex: 1; 
  // This ensures, all extra space is stretched by this class. Remaining will stretch to own height
}

/* Only to distinguish. No need to give body height  */

header {
background-color: red;
}
main {
background-color: green;
}
footer {
background-color: blue;
}

body {
height: 300px;
}

  
HEADER
  

    This is main section
