Youngsters' component with full-height being nudged by brothers and sisters

I am facing a challenge with a simple structure:

<div class="parent">
    <h1>Element taking space</h1>
    <div class="stretch">
        Not much content, but needs to be stretched to the end.
    </div>
</div>

The issue lies in the fact that the parent div has a fixed height, and I want div.stretch to expand all the way to that height, regardless of its limited content. Using height: 100% works initially, but once additional elements are added, it no longer stretches.

My understanding is that specifying height: 100% makes the element match the exact same absolute/computed height as the parent, rather than occupying the remaining space after considering other elements.

While using overflow: hidden would hide any overflow, that is not a suitable solution for me in this case.

Is there a CSS-only method to achieve this desired outcome?

Answer 1

Answer №1

Since the original query was made, a more effective method for achieving this task has emerged: flex-box.

To implement this solution, simply set the parent element's display to "flex" and flex-direction to "column". Then adjust the height of the child element you want to stretch by setting it to "inherit". This will make the child inherit the remaining available space within its parent element.

In the code snippet below, note that lines marked with /* important */ are crucial for the functionality described; the additional CSS is included for visual clarity:

.parent {
  display: flex; /* important */
  flex-direction: column; /* important */
  height: 150px;
  border: 6px solid green;
}

h1 {
  background: blue;
  margin: 0px;
  height: 90px
}

.stretch {
  background: red;
  height: inherit; /* important */
}

<div class="parent">
    <h1>Element taking space</h1>
    <div class="stretch">
        Not much content, but needs to be stretched to the end.
    </div>
</div>

If you float the h1 element, it will work regardless of its height, and the content of the stretch element will automatically be pushed below it. However, I'm not entirely sure if this meets your requirements.

EDIT: If you're unsure about the browser support you need, consider setting the display to table on .parent and have .stretch inherit the height. Then nest the column divs inside .stretch and float them for a similar effect.

To auto fill the child based on the height of your H1 element, you can follow this CSS code:

.parent {
  background-color: #eee;
  border: 1px solid black; 
  width: 300px; 
  height: 600px; 
  position:relative; 
}

h1 { Height: 100px; }

.stretch {
  background-color:#dddddd; 
  position: absolute; 
  left: 0; 
  width: 100%; 
  top: 100px; 
  bottom: 0; 
}

If you're unsure about the height of the H1 element, using JavaScript or thgaskell's method might be necessary.

Answer №4

Have you considered using the display:table properties for your layout requirements?

Note: This solution may seem similar to thgaskell's answer, but instead of relying on floats, I am utilizing table-row and table-cell displays which may better suit your needs.

You can view the code snippet on jsfiddle here: http://jsbin.com/abcdef/123/edit

.container {

  background-color: #ccc;
  border: 1px solid black;
  width: 800px;
  height: 800px;
  display:table;

}

h2 {
  display:table-row;
  width:100%;
}


.block{

  vertical-align:top;
  display:table-cell;
  height:100%;
  background-color: #ddd;

}

This example covers your h1 element as the .stretched overlaps it. You can workaround this by adding z-index: 1; to your h1 element, although it may affect text visibility in the .stretched element.

It is important to have position:relative; on the parent div for position:absolute to work properly. Absolutely positioned elements will cover other elements unless their z-index is higher or they are its children.
