Difference between inline-flex and inline-block in CSS

CSS inline-flex and inline-block are values of the CSS display property that control how elements align and behave within their containers. Both make elements flow inline while providing different layout capabilities.

Syntax

selector {
    display: inline-block;
}

selector {
    display: inline-flex;
}

Key Differences

  • CSS inline-block: Allows an element to flow inline with other elements while maintaining block-level characteristics like width and height. Children follow normal document flow.
  • CSS inline-flex: Creates an inline-level flex container where children are laid out using flexbox rules with full alignment control.

Example: Comparing inline-block and inline-flex

The following example demonstrates the difference between inline-block and inline-flex

<!DOCTYPE html>
<html>
<head>
<style>
    .container {
        background-color: #f0f0f0;
        margin-bottom: 20px;
        padding: 10px;
    }
    
    .child {
        width: 80px;
        height: 60px;
        margin: 5px;
        background-color: #4CAF50;
        color: white;
        text-align: center;
        line-height: 60px;
    }
    
    .inline-block {
        display: inline-block;
    }
    
    .inline-flex {
        display: inline-flex;
        align-items: center;
        justify-content: center;
    }
</style>
</head>
<body>
    <h3>inline-block Elements</h3>
    <div class="container">
        <div class="child inline-block">Box 1</div>
        <div class="child inline-block">Box 2</div>
        <div class="child inline-block">Box 3</div>
    </div>

    <h3>inline-flex Elements</h3>
    <div class="container">
        <div class="child inline-flex">Box 1</div>
        <div class="child inline-flex">Box 2</div>
        <div class="child inline-flex">Box 3</div>
    </div>
</body>
</html>
Both sections show three green boxes arranged horizontally. The inline-flex boxes demonstrate better text centering due to flexbox alignment properties.

Comparison Table

Feature inline-block inline-flex
Layout Behavior Inline-level with block properties Inline-level flex container
Child Layout Normal block/inline flow Flexbox layout rules
Alignment Control Limited to margins/padding Full flexbox alignment
Flexbox Support Not available Complete flexbox features
Best Use Case Simple inline layout with custom size Complex child alignment within inline container

Conclusion

Use inline-block for simple inline layouts with custom dimensions. Choose inline-flex when you need advanced alignment control and flexbox features within an inline container.
