Is there a way to assess the height of a container and adjust the CSS accordingly?

Imagine you have a container that fills 100% of the page with a footer positioned at the bottom left within that container. The footer is set to be at left:0px and bottom:0px.

Using JQuery, is it possible to detect the height of the container and, if it falls below a certain threshold, remove the CSS that positions the footer at 0px 0px?

Here is a sample HTML structure:

<div class="container">
    <div class="footer">
    </div>
</div>

And here is a sample CSS styling:

.container { width:100%; }
.footer { height:42px; position:absolute; bottom:3px; left:0px; width:100%; }

Answer №1

To achieve this effect with jQuery, you can utilize the following code snippet:

var $containerHeight = $('.container').height();
if(height < yourCustomNumber) {
  $('.footer').css({
    position: 'static',
    bottom: 'auto',
    left: 'auto'
  });
}

Answer №2

Do we really need that though? Is there an issue with the code snippet below?

.box { }
.footer { height:60px; margin-bottom: 5px; }

The footer will still remain at the bottom/end of the box.
