What is Display flex in css?

If you are new to web development, you may have heard about “display flex” but may not know what it is or how to use it. In this article, we will explain what display flex is, how it works, and how to use it to create flexible layouts on your web pages.

Introduction

In CSS, the display is a property that defines how an HTML element should be displayed on a web page. it is a value for the display property that creates a flexible container that can hold a group of flex items. The flex container adjusts the size and position of the flex items within it, allowing you to create flexible layouts that adjust to different screen sizes.

How Does Display Flex Work?

When you set the display property of an HTML element to “flex,” it becomes a flex container. The child elements of the flex container become flex items. By default, flex items are laid out in a row, with the first item at the start of the row and the last item at the end of the row.

You can adjust the layout of the flex items by using various properties, such as justify-content, align-items, and flex-wrap. For example, the justify-content property allows you to align the flex items along the main axis (the row by default) of the flex container, while the align-items property aligns the items along the cross-axis (the column by default).

How to Use Display Flex(css flex)

To use it, you need to define a container element and set its display property to “flex.” Then, you can add child elements to the container and style them using various flex properties.

Here is an example of how to use it to create a simple navigation menu:

<nav class="menu">
  <a href="#">Home</a>
  <a href="#">About</a>
  <a href="#">Services</a>
  <a href="#">Contact</a>
</nav>

<style>
.menu {
  display: flex;
  justify-content: space-between;
  align-items: center;
}
.menu a {
  margin-right: 20px;
}
</style>

In this example, we defined a container element with the class “menu” and set its display property to “flex.” We also set the justify-content property to “space-between,” which creates equal spacing between the flex items. The align-items property centers the items vertically within the container. Finally, we added some margin to the links using the “.menu a” selector.
