I just answered as similar question in here:

Position footer at bottom of page having fixed header

I'm pretty new at web development, and I know this has been answered already, but this is the easiest way I found to solve it and I think is somehow different. I wanted something flexible because the footer of my web app has a dynamic height, I ended up using FlexBox and a spacer.

1. Start by setting the height for your html and body

html, body {
    height: 100%;
    display: flex;
    flex-direction: column;
    margin: 0px;
}

I'm assuming a column behavior for our app, in the case you need to add a header, hero or any content vertically aligned.

2. Create the spacer class

.spacer {
    flex: 1; 
}

3. So later on your HTML could be something like

  
    
 Header 
    Some content...
    

    
 Footer
