HTML tutorial: How to use Flexbox for equal spacing layout

In web design and development, layout has always been an important link. In layout, achieving equal spacing layout is often a relatively complex task. However, with the rise of Flexbox technology, achieving equal spacing layout has become easier and more flexible. This article will introduce how to use Flexbox to implement equal spacing layout, and give specific code examples to help beginners get started quickly.

What is Flexbox?
Flexbox is a technology that defines and controls the layout of the flexible box model in CSS. It provides a simple, flexible and powerful way to lay out and arrange elements, both horizontally and vertically. The features of Flexbox include adaptive, automatic adjustment and equal spacing layout.

How to start using Flexbox?
Before using Flexbox, we first need to introduce a CSS style sheet into the HTML file and set the corresponding style.

<link rel="stylesheet" href="flexbox.css">

Next, in the CSS file, we need to create a Flex container and set some properties to it to achieve equal spacing layout.

.container {
  display: flex;
  justify-content: space-between;
}

In the above code, we use display: flex to specify the Flex container, and use justify-content: space-between to achieve equal spacing layout. This property will distribute Flex items evenly within the Flex container while maintaining equal spacing between items.

Next, we need to add some Flex items in the Flex container to show the effect of equal spacing layout.

<div class="container">
  <div class="item">项目1</div>
  <div class="item">项目2</div>
  <div class="item">项目3</div>
</div>

In the above code, we create a Flex container containing three Flex projects. Each Flex item is represented by a <div> tag, and their style is specified using class="item".

Finally, in the CSS file, we can set some styles for the Flex items to make them more beautiful in the equally spaced layout.

.item {
  padding: 10px;
  background-color: #ccc;
}

In the above code, we use the padding property to set the padding of each Flex item, and the background-color property to set their background color.

Through the above steps, we have completed the basic operations of using Flexbox to implement equal spacing layout. Next, we can adjust and optimize other properties of Flexbox according to actual needs.

Introduction to other Flexbox properties:

1. align-items: flex-start/center/flex-end/strech; - Set the vertical alignment of Flex items.
2. flex-direction: row/column/row-reverse/column-reverse; - Set the arrangement direction of Flex items in the Flex container.
3. flex-wrap: nowrap/wrap/wrap-reverse; - Set whether Flex items are wrapped in new lines.
4. flex-grow: 0~n; - Set the proportion of Flex items in the remaining space.
5. flex-shrink: 0~n; - Set the scaling ratio of Flex items when there is insufficient space.

Summary:
By using Flexbox technology, we can more easily and flexibly implement equal spacing layout in web page layout. Flexible use of Flexbox attributes can make various adjustments and optimizations according to needs. I hope that the specific code examples given in this article can help readers better grasp the application of Flexbox and improve the efficiency of web design and development.
