CSS Sticky Footer: Troubleshooting and Implementing

Many web developers encounter challenges when implementing a CSS sticky footer on their websites. One common issue is the occurrence of content extending beyond its container, causing undesirable scroll bars. Another issue is when the background image on the footer div is truncated and does not extend the full height of the page.

Troubleshooting the Content Overflow

In the provided HTML, the #content div overflows its container and extends beyond the #page div. To resolve this, you can set a maximum height or a overflow property for the #content div. Here's a modified CSS:

#content {
    max-height: calc(100% - 40px);
    overflow: auto;
}

Extending the Background Image Height

To extend the background image on the #footer div to the full height of the page, you can set its position to absolute and adjust its height accordingly:

#footer {
    position: absolute;
    bottom: 0;
    height: calc(100% - 40px);
}
