How to use CSS properties to create responsive layout

With the popularity of mobile devices and the rise of multi-terminals, responsive layout has attracted more and more attention from developers. By using CSS properties, we can easily implement responsive layout so that web pages can achieve good display effects on different terminals. This article explains how to use CSS properties to create responsive layouts and provides some concrete code examples.

1. Media query

Media query is one of the most commonly used methods to implement responsive layout. By using media queries, we can apply different CSS styles based on the device's characteristics and screen size. The following is a simple media query example:

@media screen and (max-width: 768px) {
  /* 在屏幕宽度小于等于768px时应用这些样式 */
  body {
    background-color: lightblue;
  }
}

The above code indicates that when the screen width is less than or equal to 768px, the background color of the body is set to light blue.

2. Flexible layout

Flexible layout is a layout method that can automatically adapt to different screen sizes. By using the CSS property flex, we can easily create flexible layouts. The following is a simple flexible layout example:

.container {
  display: flex;
}

.item {
  flex: 1;
  height: 100px;
  background-color: lightblue;
}

In the above code, .container represents the container element, and .item represents each child item. Use display: flex to make the container element a flex layout, and flex: 1 to set the width of each child to an equal proportion.

3. Grid layout

Grid layout is a new layout method in CSS3. By using the CSS attribute grid, we can easily create a grid layout. The following is a simple grid layout example:

.container {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-gap: 20px;
}

.item {
  background-color: lightblue;
  height: 100px;
}

In the above code, .container represents the container element, and .item represents each child item. Use display: grid to set the container element to a grid layout, while grid-template-columns defines the number and column width of the grid, and grid-gap defines the spacing between grids.

4. Media query and elastic layout

Combining media query and elastic layout, we can create a more flexible responsive layout. The following is an example using a combination of media queries and elastic layout:

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

.item {
  flex: 1;
  min-width: 300px;
  max-width: 500px;
  height: 200px;
  background-color: lightblue;
}

@media screen and (max-width: 768px) {
  .item {
    min-width: 100px;
    max-width: none;
  }
}

In the above code, when the screen width is less than or equal to 768px, the minimum width of each child item will become 100px. By using media queries, we can adjust the width of the children according to different screen sizes, thus achieving a responsive layout.

Summary:

By using CSS properties, we can easily create responsive layouts. Media queries, flexible layout and grid layout are commonly used methods to implement responsive layout. Developers can choose the appropriate layout method according to specific needs. Hopefully the specific code examples in this article will help readers better understand how to use CSS properties to create responsive layouts.
