Guide to implementing responsive grid layout using CSS

Grid layout plays an important role in modern web design, allowing web pages to flexibly adapt to different devices and screen size. In this article, we will share some guidelines for implementing responsive grid layout using CSS and provide specific code examples for your reference.

1. Using CSS Grid Layout
   CSS Grid Layout is a powerful and flexible web page layout technology that allows us to organize web content in the form of a grid. First, we need to apply the display: grid; property on the parent container to enable grid layout. Then, create a grid structure by defining the size and number of rows and columns. Here is a basic example:

.container {
  display: grid;
  grid-template-columns: repeat(4, 1fr);  /* 定义4个相等的列 */
  grid-gap: 10px;  /* 定义列之间的间距 */
}

2. Responsive Grid Layout
   To achieve responsive layout, we can use media queries to adjust the layout of the grid according to the device's screen size. . For example, on smaller screens we can reduce the number of columns to 2 and change the size and spacing of the columns. The following is an example of implementing responsive grid layout:

.container {
  display: grid;
  grid-template-columns: repeat(4, 1fr);  /* 定义4个相等的列 */
  grid-gap: 10px;  /* 定义列之间的间距 */
}

@media screen and (max-width: 600px) {
  .container {
    grid-template-columns: repeat(2, 1fr);  /* 在较小的屏幕上只有2个列 */
    grid-gap: 5px;  /* 缩小列之间的间距 */
  }
}

3. Adaptive Grid Layout
   In addition to implementing responsive layout through media queries, we can also use auto-fill and minmax properties to create adaptive grid layout. auto-fill allows automatic filling of items in the grid, minmax can limit the size range of items. Here is an example of an adaptive grid layout:

.container {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));  /* 列宽度最小200px，为了适应屏幕自动填充网格中的项目 */
  grid-gap: 10px;  /* 定义列之间的间距 */
}

4. Align and resize items
   In a grid layout, we can pass justify-* and align-* properties to align items (horizontally and vertically), and span properties to resize items. The following are some commonly used examples:

.item {
  /* 水平方向对齐 */
  justify-self: start;  /* 靠左对齐 */
  justify-self: center;  /* 居中对齐 */
  justify-self: end;  /* 靠右对齐 */
  
  /* 垂直方向对齐 */
  align-self: start;  /* 靠上对齐 */
  align-self: center;  /* 居中对齐 */
  align-self: end;  /* 靠下对齐 */
  
  /* 调整大小 */
  grid-column: span 2;  /* 占据2个列 */
  grid-row: span 3;  /* 占据3个行 */
}

Through the above guide, we can use CSS to implement responsive grid layout, so that web pages can show good layout effects on different devices and screen sizes. I hope the above content will be helpful to you when developing web pages.
