display: flex vs. display: inline-flex : Understanding Cascading Style Sheets (CSS) is crucial for creating visually appealing and user-friendly websites in the dynamic field of web development. Among the many CSS properties, display is one of the most important tools for managing how HTML components are laid out and presented. Flex and inline-flex, two closely related display property values, are essential for providing responsive and flexible layouts with the flexbox architecture. Although the two values have comparable functionality, they behave differently, and developers must learn to understand and use them properly. (Read Full Article)

Exploring display: flex

With a basic understanding of flexbox and its advantages, let’s delve into the specifics of display: flex and its behavior in CSS layouts.

Understanding display: flex

The display: flex property is used to construct a flex container, which provides a flex layout context to its direct descendants. When applied to an element, display: flex converts it into a flex container, with its children automatically becoming flex items. These flex components are then placed along a primary axis, which is normally horizontal (row) by default but can be changed using the flex-direction attribute.(Read full Article)

Let’s explore the usage of display: flex with a practical example:

<!DOCTYPE html>
<html lang="en">

<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Display Flex and Display Inline Flex</title>
<style>
body,
section,
div {
margin: 0;
padding: 0;
}

.container {
max-width: 1000px;
margin-left: auto;
margin-right: auto;
padding: 10px;
}

.flex-container {
display: flex;
/* flex-direction: row; */
}

.div-box1 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightblue;


}

.div-box2 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightcoral;


}

.div-box3 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightgreen;

}
</style>
</head>

<body>
<section class="container">
<section class="flex-container">
<div class="div-box1"></div>
<div class="div-box2"></div>
<div class="div-box3"></div>
</section>
</section>
</body>

</html>

.flex-container: Styles the container for flex items with display: flex, which enables a flex context for its direct children.

.div-box1, .div-box2, .div-box3: Styles the individual flex items (divs) with a flex-grow property of 1 (equal distribution of remaining space), a minimum width and height of 100px, and different background colors for visualization.

Exploring display: inline-flex

While display: flex is suitable for creating block-level flex containers, display: inline-flex is used to create inline-level flex containers. Let’s explore the behavior of display: inline-flex and its advantages in CSS layouts.

Understanding display: inline-flex

The display: inline-flex property creates an inline-level flex container that easily integrates with other inline components in the document flow. Inline elements, as opposed to block-level components, do not generate line breaks before or after them, making them excellent for constructing compact and inline layouts.

<!DOCTYPE html>
<html lang="en">

<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Display Flex and Display Inline Flex</title>
<style>
body,
section,
div {
margin: 0;
padding: 0;
}

.container {
max-width: 1000px;
margin-left: auto;
margin-right: auto;
padding: 10px;
}

.flex-container {
display: inline-flex;
/* flex-direction: row; */
}

.div-box1 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightblue;


}

.div-box2 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightcoral;


}

.div-box3 {
flex: 1;
min-width: 100px;
min-height: 100px;
background-color: lightgreen;

}
</style>
</head>

<body>
<section class="container">
<section class="flex-container">
<div class="div-box1"></div>
<div class="div-box2"></div>
<div class="div-box3"></div>
</section>
</section>
</body>

</html>

.flex-container: This class is applied to another section element. It sets the display property to inline-flex, which means its child elements will be laid out as flex items inline with the text flow.

.div-box1, .div-box2, .div-box3: These classes are applied to div elements within the flex container. Each div represents a flex item. They are styled similarly with flex: 1; to allow them to grow and shrink equally within the flex container, min-width: 100px; and min-height: 100px; to set a minimum size for each item, and different background colors to visually distinguish them (lightblue, lightcoral, lightgreen).

Key Differences and Use Cases

After discussing the ideas behind display: flex and display: inline-flex, as well as each of its benefits, let’s review the main distinctions between the two values and the scenarios in which they are used:

  1. Display Type:
    display: flex creates a block-level flex container.
    display: inline-flex generates an inline-level flex container.
  2. Integration into Document Flow:
    display: flex elements break the flow of surrounding elements, behaving as block-level elements.
    display: inline-flex elements seamlessly integrate into the document flow, behaving as inline-level elements.
  3. Line Break Behavior:
    display: flex elements cause line breaks before and after the flex container, stacking elements vertically.
    display: inline-flex elements do not cause line breaks, allowing other inline elements to sit beside them on the same line.

It is essential to comprehend these distinctions in order to choose the right display property for the intended layout and integration needs of the web design. For each property, the following are some typical usage cases:

  1. display: flex Use Cases:
    Creating complex layouts that require breaking the flow of surrounding elements.
    Designing components that span the full width of the container or viewport.
    Implementing responsive designs that adapt to various screen sizes and orientations.
  2. display: inline-flex Use Cases:
    Incorporating flexible components within text passages or inline content.
    Constructing compact layouts where elements need to align horizontally without causing line breaks.
    Designing inline navigation menus or inline forms that seamlessly blend with surrounding text.

By leveraging the appropriate display property, developers can craft versatile and visually appealing layouts that enhance the user experience across different devices and screen sizes. (Read Full Article)

Finally, understanding the differences between display: flex and display: Inline-flex allows developers to construct versatile and visually pleasing CSS layouts. While both attributes allow for flexible layouts utilizing the flexbox concept, they differ in their behavior regarding display type, integration into the document flow, and line break management.

Developers can create responsive designs that improve the user experience across several devices and screen sizes by carefully using CSS’s display: flex and display: inline-flex properties. Experimenting with these characteristics creates a world of possibilities for designing dynamic and flexible layouts, stretching the limits of web development inventiveness.

Whether you’re creating a simple webpage, a large web application, or a mobile-responsive website, remember to use the power of display. Flex and display: Use inline-flex to design layouts that are both practical and visually appealing. Flexbox offers endless possibilities, making the future of online design more flexible than ever before.
