Can the height of a container be dynamically adjusted to match the height of its child element with absolute positioning?

My website includes a search field where users can type in their queries. However, I am facing an issue with the autocomplete feature causing layout problems on certain screen sizes.

In order to prevent the autocomplete list from affecting the overall page layout, I have set its position attribute to absolute. Unfortunately, this sometimes results in the autocomplete list extending beyond the boundaries of the HTML element and overlapping with the footer section.

I am aware that using position: absolute removes the element from the normal document flow, but I am looking for a solution to adjust the height of the container element based on the child element with absolute positioning. Is there a CSS technique to achieve this, or do you recommend another approach?

Answer №1

Given Information:

The footer has a height of 60px;

The footer is contained within a div with the id "footer";

The background behind the footer extends to the window, rather than being confined within a specific division;

If JQuery is available:

//Replace 120 below with the height of your footer, including padding, and how far the search bar is from the top of the screen
var height = ($(window).height() - 120); 
$('#footer').css({"height", height});

To enhance the visual appeal, you can replace the adjustment above with...

$('#footer').stop().animate({height: height});

Answer №2

Perhaps you are referring to positioning the autocomplete list below the footer.

To achieve this, you can utilize the css z-index property to display your autocomplete list above the footer element.

Answer №3

To achieve this effect, Set Overflow-y to scroll with a maximum height of 200px and position it absolutely while giving it a z-index of 2

Answer №4

html {
    overflow: auto;
}

body {
    overflow: hidden;
}

.autocomplete-list {
     margin-bottom: [height of footer]
}

If the content in the list exceeds the body height, there may be an issue with your CSS.

The CSS above ensures that nothing overflows outside the body and if it does, a scrollbar will appear.

The margin-bottom on the autocomplete-list maintains space above the footer.
