How to Make Div Fit Contents: Complete Guide

Learn CSS techniques to make div containers automatically size to their contents, including tables. Discover inline-block, fit-content, and flexbox solutions for responsive layouts.

Question

How can I make a div not larger than its contents?

I have a layout similar to:

html
<div>
    <table>
    </table>
</div>

I would like for the div to only expand to as wide as my table becomes.

To make a div shrink to fit its contents, use CSS properties like display: inline-block or width: fit-content on the div container, which will allow it to automatically size to match the width of its child table without expanding beyond that width. The key is to avoid setting explicit width constraints on the parent while using sizing properties that respect the natural dimensions of the contained elements.

Contents


Core CSS Solutions

The most fundamental approach is using display: inline-block on the div container. This property allows elements to flow naturally within the document while respecting their content size.

css
div {
    display: inline-block;
}

This makes the div behave like an inline element but still allows block-level properties like padding and margin. The div will automatically shrink to fit its contents, including the table’s width.

Another traditional method is to use overflow: hidden combined with not setting any width on the parent container:

css
div {
    overflow: hidden;
    /* No width property set */
}

This approach works because without an explicit width, the div will try to fill its available space, but overflow: hidden constrains it to the content dimensions.

Modern CSS Properties

Modern CSS offers more precise control through the fit-content function:

css
div {
    width: fit-content;
}

The fit-content function calculates the appropriate size as min(maximum size, max(minimum size, preferred size)). In this case, it means the div will size to fit its contents while respecting any minimum or maximum width constraints if they exist.

For even more control, you can use:

css
div {
    max-width: fit-content;
}

This ensures the div never grows larger than its contents while still allowing it to shrink to fit.

Flexbox Approach

Flexbox provides another powerful approach to control container sizing:

css
div {
    display: flex;
    flex-shrink: 0;
    justify-content: flex-start;
}

The flex-shrink: 0 property prevents the flex item from shrinking below its content size, effectively making it fit its contents.

For a more straightforward flexbox approach:

css
div {
    display: inline-flex;
}

inline-flex combines the benefits of inline layout with flexbox capabilities, allowing the container to size to its contents.

Practical Implementation Example

Here’s a complete practical example for your specific case:

html
<!DOCTYPE html>
<html>
<head>
    <style>
        /* Method 1: Using inline-block */
        .container-inline-block {
            display: inline-block;
            border: 2px solid #007bff;
            padding: 10px;
            margin: 10px;
        }
        
        /* Method 2: Using fit-content */
        .container-fit-content {
            width: fit-content;
            border: 2px solid #28a745;
            padding: 10px;
            margin: 10px;
        }
        
        /* Method 3: Using inline-flex */
        .container-inline-flex {
            display: inline-flex;
            border: 2px solid #dc3545;
            padding: 10px;
            margin: 10px;
        }
        
        table {
            border-collapse: collapse;
            width: 300px; /* Fixed width for demonstration */
        }
        
        table, th, td {
            border: 1px solid #333;
        }
        
        th, td {
            padding: 8px;
            text-align: left;
        }
    </style>
</head>
<body>
    <h3>Method 1: display: inline-block</h3>
    <div class="container-inline-block">
        <table>
            <tr>
                <th>Name</th>
                <th>Age</th>
            </tr>
            <tr>
                <td>John Doe</td>
                <td>25</td>
            </tr>
            <tr>
                <td>Jane Smith</td>
                <td>30</td>
            </tr>
        </table>
    </div>
    
    <h3>Method 2: width: fit-content</h3>
    <div class="container-fit-content">
        <table>
            <tr>
                <th>Name</th>
                <th>Age</th>
            </tr>
            <tr>
                <td>John Doe</td>
                <td>25</td>
            </tr>
            <tr>
                <td>Jane Smith</td>
                <td>30</td>
            </tr>
        </table>
    </div>
    
    <h3>Method 3: display: inline-flex</h3>
    <div class="container-inline-flex">
        <table>
            <tr>
                <th>Name</th>
                <th>Age</th>
            </tr>
            <tr>
                <td>John Doe</td>
                <td>25</td>
            </tr>
            <tr>
                <td>Jane Smith</td>
                <td>30</td>
            </tr>
        </table>
    </div>
</body>
</html>

This example demonstrates three different approaches to achieve your goal, with visual indicators so you can see how each method works in practice.

Common Pitfalls and Solutions

Issue 1: Parent container has explicit width
If the parent div has a fixed width set (like width: 100% or width: 500px), it won’t shrink to fit contents. Solution: Remove the width property or use max-width instead.

Issue 2: Table extends beyond container
Sometimes tables can extend beyond their intended bounds due to content. Solution: Add table-layout: fixed to the table and set overflow: auto to the container:

css
div {
    width: fit-content;
    overflow: auto;
}

table {
    table-layout: fixed;
    width: 100%;
}

Issue 3: Long content breaks layout
When table cells contain very long text without spaces, they can expand the table beyond intended bounds. Solution: Use word-wrap: break-word or hyphens: auto on table cells:

css
td {
    word-wrap: break-word;
    hyphens: auto;
}

Browser Compatibility

All the methods discussed have excellent browser support:

  • display: inline-block - Supported in all browsers since IE8
  • width: fit-content - Supported in all modern browsers (IE11 with partial support)
  • display: inline-flex - Well-supported across all modern browsers

For maximum compatibility, especially with older browsers, display: inline-block remains the most reliable choice. According to the MDN Web Docs, fit-content has been supported in all major browsers since 2017, making it a safe choice for most modern web development.

Conclusion

To make a div container shrink to fit its contents, you have several effective CSS approaches:

  • Use display: inline-block for maximum browser compatibility
  • Apply width: fit-content for modern, precise sizing control
  • Implement display: inline-flex for flexbox-based layouts
  • Avoid setting explicit width properties on containers that need to shrink

The best approach depends on your specific requirements and browser support needs. For most modern web projects, width: fit-content provides the cleanest solution, while display: inline-block remains the most reliable choice for maximum compatibility.

Remember to also consider table-specific styling properties like table-layout: fixed and cell wrapping to ensure your table contents behave as expected within the constrained container.
