How does responsive layout adapt to different devices?

What problems does responsive layout solve?

With the rapid development of mobile Internet, more and more users tend to use mobile devices to access the Internet, instead of being limited to traditional desktop computers. This brings new challenges to web design and development: adaptation issues between different screen sizes and device types. To solve this problem, responsive layout came into being.

The so-called responsive layout is the ability to automatically adjust the layout and style of the page according to the user's device and screen size, so that it can obtain the best browsing experience on different devices. Responsive layout is not just about simply adapting to the screen size, but also involves comprehensive consideration of user interaction and functional requirements.

Through responsive layout, we can solve the following problems:

Provide a high-quality user experience:
Using responsive layout can ensure that the web page can be viewed on different devices Presented in the best way to maintain a good user experience whether on mobile phones, tablets or desktop computers. Page elements automatically adjust layout according to screen size, maintaining readability and ease of use, and preventing users from needing to zoom in or slide the page to browse content.
Improve website accessibility:
Responsive layout can make the website more accessible. Users no longer need to search and download specific applications or browser plug-ins on different devices to browse the web. The website can be accessed directly from the browser regardless of the device used.
Convenient maintenance and updates:
Using responsive layout can avoid maintaining multiple independent website versions for different devices, and only needs to maintain a unified code base. It is also more convenient to update and improve the functions of the website. You only need to make modifications in the corresponding layout and style.

The following is a sample code using responsive layout:

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <style>
        * {
            box-sizing: border-box;
        }

        .container {
            width: 100%;
            max-width: 1200px;
            margin: 0 auto;
            padding: 20px;
        }

        .content {
            width: 100%;
            float: left;
        }

        @media screen and (min-width: 768px) {
            .content {
                width: 70%;
                float: left;
            }
        }

        @media screen and (min-width: 1024px) {
            .content {
                width: 60%;
                float: left;
            }
        }
        .sidebar {
            width: 100%;
            float: left;
        }

        @media screen and (min-width: 768px) {
            .sidebar {
                width: 30%;
                float: left;
            }
        }

        @media screen and (min-width: 1024px) {
            .sidebar {
                width: 40%;
                float: left;
            }
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="content">
            <h1>这是一个响应式布局示例</h1>
            <p>这是一段内容</p>
        </div>
        <div class="sidebar">
            <h2>侧边栏</h2>
            <ul>
                <li>菜单项1</li>
                <li>菜单项2</li>
                <li>菜单项3</li>
            </ul>
        </div>
    </div>
</body>
</html>
