CSS 网格系统(Grid System)是 CSS3 中的一种布局模型,它提供了一种更加灵活和高效的方式来设计网页布局。使用网格系统,我们可以轻松创建复杂的布局,而不需要使用传统的浮动或定位方法。

基本概念

  • 容器(Container):网格系统的基础是容器,它是网格的父元素,通常是一个 div
  • 行(Row):容器内部的水平区域,用于放置网格单元。
  • 列(Column):容器内部的垂直区域,同样用于放置网格单元。
  • 网格单元(Grid Cell):行和列交叉形成的区域,是放置内容的单元。

使用方法

.container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr; /* 定义三列,每列占据相同的空间 */
  grid-gap: 10px; /* 定义行和列之间的间隔 */
}

示例

下面是一个简单的网格布局示例:

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

# CSS Grid System

CSS Grid Layout is a powerful and flexible layout system in CSS3 that provides a more efficient way to design web layouts. With Grid Layout, you can easily create complex layouts without relying on traditional float or positioning methods.

## Basic Concepts

- **Container**: The foundation of the grid system is the container, which is the parent element of the grid, typically a `div`.
- **Row**: A horizontal region within the container used to place grid items.
- **Column**: A vertical region within the container used to place grid items.
- **Grid Cell**: The area where rows and columns intersect, used to place content.

## Usage

```css
.container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr; /* Define three columns, each taking equal space */
  grid-gap: 10px; /* Define the gap between rows and columns */
}

Example

Below is a simple grid layout example:

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