How to set css browser size

CSS browser size setting exploration

As front-end developers, we often use CSS to design the layout and style of web pages. As for the size of the web page, we can use CSS to set it so that the web page can have appropriate rendering effects on different browsers and devices.

First of all, let’s first understand the concepts of browser window size and web page size. The browser window size refers to the size of the browser window, while the size of the web page refers to the overall size of the web page, including the visible area within the browser window and the scroll bar area of ​​the web page.

When we use CSS to set the size of a web page, it mainly includes the following methods:

1. Use percentage

Using percentage can make the size of the web page change with the browsing Adaptively adjusts to changes in browser window size. For example:

body {
    width: 100%;
    height: 100%;
}

After setting this, the web page can display the complete page content on screens with different resolutions and browser window sizes.

2. Use fixed values

In addition to using percentages, we can also use fixed values ​​to set the size of web pages. For example:

body {
    width: 960px;
    height: 600px;
}

After setting this, the width of the web page will be fixed at 960 pixels and the height at 600 pixels. However, this setting method is not flexible enough and cannot adjust the size of the web page according to changes in the browser window size.

3. Use the minimum width and maximum width

Using the minimum width and maximum width can adaptively adjust the size of the web page within a certain range. For example:

body {
    min-width: 960px;
    max-width: 1200px;
}

After setting like this, the width of the web page will be adaptively adjusted, but it will not exceed the maximum width of 1200 pixels, and will not be less than the minimum width of 960 pixels.

4. Use media queries

Use media queries to make targeted settings for different devices and screen sizes. For example:

@media only screen and (max-width: 768px) {
    body {
        width: 100%;
        height: auto;
    }
}

This setting method allows the web page to adaptively resize on small screen devices.

In summary, it is very important to use CSS to set the size of web pages. With appropriate settings, we can enable web pages to obtain appropriate rendering effects on different devices and browser windows. At the same time, we also need to flexibly choose different setting methods according to actual needs to achieve the best results.
