Interpretation of CSS responsive layout properties: media queries and min-width/max-width

CSS responsive layout is a layout method that can automatically adapt to the screen size and resolution of different devices. In CSS, there are two main properties used to implement responsive layout: media queries and min-width/max-width.

First, let’s interpret media queries. It is a feature in CSS3 through which we can apply corresponding styles according to different media types and browser widths. Before using media queries, you first need to understand the media types, such as screen (for computer screens), print (for printers), speech (for speech synthesizers), etc. Next we use a specific code example to illustrate how to use media queries.

/* 当浏览器宽度小于600px时，应用以下样式 */
@media screen and (max-width: 600px) {
    body {
        background-color: lightblue;
    }
    h1 {
        color: red;
    }
}

/* 当浏览器宽度大于600px时，应用以下样式 */
@media screen and (min-width: 601px) {
    body {
        background-color: lightgreen;
    }
    h1 {
        color: blue;
    }
}

In the above code, we use the @media keyword to define the media query, and specify the media type as computer screen through the screen keyword. Then use the and keyword to connect the media type and a conditional expression, which consists of the max-width or min-width attribute and a specific width value. When the browser width is less than 600px, the styles defined in the first media query are applied; when the browser width is greater than 600px, the styles defined in the second media query are applied.

Next, let’s interpret the min-width and max-width attributes. They are used to limit the minimum and maximum width of an element. When the browser width is less than min-width, the element will be displayed according to the width set by min-width, and when the browser width is greater than max-width, the element will be displayed according to the width set by max-width. Here is a simple code example:

.container {
    width: 100%;
    max-width: 1200px;
    min-width: 600px;
    margin: 0 auto;
}

In the above code, we create a class called .container, set its width to 100%, the maximum width to 1200px, the minimum width to 600px, and Displayed in the center through the margin attribute.

By using the min-width and max-width attributes, we can set a flexible width range for the element so that it can adapt to the screen sizes of different devices and browsers.

In summary, CSS media queries and min-width/max-width attributes are important tools for implementing responsive layout. By properly using these attributes, we can apply corresponding styles according to different media types and browser widths, thereby achieving a layout that adapts to multiple devices.
