Creating a DIV to Fill the Space Between Header and Footer DIV
When designing a website layout, it's often desirable to have a header, footer, and content area that flows seamlessly. For this purpose, DIVs offer greater flexibility compared to traditional tables.
To ensure the footer remains at the bottom of the page and the content DIV adjusts dynamically to fill the space between the header and footer, a simple solution lies in using Flexbox.
Flexbox Implementation
Flexbox provides a means to arrange elements on a page, allowing them to flow in both a row and a column. In our case, we want the layout to flow in a column, with the header and footer sticking to their respective top and bottom positions.
The HTML structure remains straightforward, with a header, main content, and footer:
<body> <header>...</header> <main>...</main> <footer>...</footer> </body>
The CSS can then be applied as follows:
html, body {
margin: 0;
height: 100%;
min-height: 100%;
}
body {
display: flex;
flex-direction: column;
}
header,
footer {
flex: none;
}
main {
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
flex: auto;
}Explanation
- flex-direction: column sets the flexbox to arrange its children vertically.
- flex: none on the header and footer prevents them from taking up any excess space.
- overflow-y: scroll enables vertical scrolling within the main content area, ensuring the page's content fits within the remaining space.
- -webkit-overflow-scrolling: touch optimizes scrolling behavior for touch devices.
- flex: auto allows the main content area to dynamically fill the remaining space between the header and footer, regardless of screen resolution.
Additional Considerations
If the content exceeds the available space, a vertical scrollbar will appear within the main content area.
By utilizing Flexbox, you can easily create a layout where the content dynamically adapts to fill the space between a fixed header and footer, resulting in a responsive and visually appealing design.
