Tips for placing a button on the bottom of a window where the content expands

Seeking a solution to ensure the submit button is always positioned at the bottom of the page. While this can be done using position: absolute, bottom, there's a requirement to address.

If the content height is less than the wrapping div height, the button should align with the bottom of the window. However, if the content exceeds the div height, then the button should remain at the bottom of the content, not the window.

An example demonstrating the second condition can be viewed on this JSFIDDLE link. Assistance is needed to achieve the first condition.

.container {
  height: 400px;
  width: 400px;
  background: red;
  overflow: scroll;
}

ul {
  list-style: none;
  margin: 0;
  padding: 0;
}

li {
  height: 100px;
  background: blue;
  margin-bottom: 10px;
  color: white;
}

button {
  display: block;
  width: 100%;
  background: black;
  height: 40px;
  color: white;
}

If you're looking for a solution, one option is to place the button outside of the container div and set specific max-width and height values to prevent overflow.

You can view examples here: https://jsfiddle.net/Lu3am0Lo/2/ for overflow, and https://jsfiddle.net/Lu3am0Lo/3/ if there's no overflow in the list.

.container {
  max-height: 400px;
  max-width: 400px;
  background: red;
  overflow: scroll;
}

It seems like you're utilizing Bootstrap in your code. One option to keep the button at the bottom of the page is by implementing a 'sticky footer' concept, achieved through setting margins on the body.

Check out the source here: https://getbootstrap.com/examples/sticky-footer/

You can also create a custom CSS class for any div (not necessarily a footer) and style it accordingly, similar to how they've used the 'footer' class.

Ensure to check whether the content within the container exceeds its boundaries - if yes, apply a specific class accordingly:

JavaScript

$(document).ready(function(){
  if ($('ul').height() > 400 ){
    $('button').addClass('overflow');
  } else {
    $('button').addClass('no-overflow');
  }
});

CSS

.no-overflow {
  position: absolute;
  bottom: 0;
}

.overflow {
  position: relative!important;
  bottom: 0;
}
