HTML tutorial: How to use Grid layout for grid free layout, specific code examples are required

Introduction:
In web development, using CSS for layout is A very important skill. Grid layout is a new feature of CSS3. It provides a more powerful and flexible layout method, allowing us to design the grid layout of web pages more freely. This article will introduce how to use Grid layout and provide specific code examples.

What is Grid layout?
Grid layout is a grid system that divides the layout of a web page into rows and columns, and creates the layout of the web page by specifying the size and position of each "cell". Grid layout can easily implement complex grid layouts, such as column layout and responsive layout.
Using Grid layout in HTML
To use Grid layout in HTML, you first need to define the grid container and grid items in CSS. The grid container is the part that contains the content of the web page, and the grid items are the child elements of the grid container.

The sample code is as follows:

<!DOCTYPE html>
<html>
<head>
<style>
.grid-container {
  display: grid;
  grid-template-columns: auto auto auto; /* 定义3列 */
  grid-gap: 10px; /* 定义单元格之间的间隔 */
  background-color: #f3f3f3;
  padding: 10px;
}

.grid-item {
  background-color: #ffffff;
  padding: 20px;
  font-size: 30px;
  text-align: center;
}
</style>
</head>
<body>

<h1>Grid布局示例</h1>

<div class="grid-container">
  <div class="grid-item">1</div>
  <div class="grid-item">2</div>
  <div class="grid-item">3</div>
  <div class="grid-item">4</div>
  <div class="grid-item">5</div>
  <div class="grid-item">6</div>
</div>

</body>
</html>

In the above code, we define a grid container containing 6 grid items, with a total of 3 columns. Each grid item has the same style, and they fill the grid in order from left to right and top to bottom.

Common properties of Grid layout

grid-template-columns: Define the number and width of columns.
grid-template-rows: Define the number and height of rows.
grid-gap: Define the gap between grid items.
grid-column: Defines the columns spanned by grid items.
grid-row: Defines the rows spanned by grid items.
justify-items: Define the alignment of grid items in columns.
align-items: Define the alignment of grid items in rows.

By using these properties, we can flexibly control the grid layout and achieve various layout effects.

Responsive layout of Grid layout
Responsive layout can be easily implemented using Grid layout. By defining different column widths and row heights, and using media queries, you can display different layouts on different screen sizes.

The sample code is as follows:

@media screen and (max-width: 600px) {
  .grid-container {
    grid-template-columns: auto;
  }
}

Copy after login

In the above code, we define a media query to modify the number of columns of the grid container to 1 when the screen width is less than 600 pixels List. In this way, on mobile devices, the grid layout will become a column layout.

Conclusion:
Grid layout is a powerful grid system that can provide flexible grid layout. By using Grid layout, we can design web page layout more freely and easily implement complex grid layout and responsive layout. I hope this tutorial will be helpful to developers who want to learn and master Grid layout. I wish you success in your web layout journey!
