How Can I Implement a Sticky Footer in CSS and Solve Common Height and Overflow Issues?

Sticky Footer Challenges in CSS and Possible Solutions

Implementing a sticky footer using CSS can present challenges when content spills beyond container boundaries, causing unnecessary scrollbars, and when the page background image does not extend the document's full height.

HTML Structure:

<div>

CSS Implementation:

/* General styles */
body {
  height: 100%;
}

#page {
  height: 100%;
  position: relative;
}


/* Content styles */
#content {
  height: 100%;
  min-height: 100%;
  position: relative;
}

/* Footer styles */
#footer {
  position: absolute;
  bottom: 0;
}

Potential Issues and Solutions:

• Excess content in #content:

  • Ensure #content's container is sized appropriately with overflow: hidden to prevent spilling over.
  • Implement a CSS Sticky Footer solution (see below for references).

• Background image not extending full page height:

  • Ensure #page is set as a flexbox or grid container and #content is a flex item or grid cell.
  • Apply flex-grow: 1 to #content to occupy the remaining space and force the background image to fill the entire height.
