    @media screen and (max-width: 768px) { /* 在屏幕尺寸小于等于768px时应用的样式 */ }
    Copy after login
  2. Use a CSS framework or tool such as Bootstrap Media query class names provided by , Foundation, etc., such as:

    <div class="col-lg-6 col-md-8 col-sm-12">...</div>

    .container {
     width: 100%;
    }
    
    .box {
     width: 50%;
    }
    Copy after login

    .container {
     display: flex;
     flex-direction: row;
     justify-content: space-between;
     align-items: center;
    }
    Copy after login

    2. Use image compression formats, such as JPEG or WebP, to reduce image file size while maintaining image quality.
    3. Use an appropriate image compression tool, such as TinyPNG or ImageOptim, to reduce the file size of your images.

    5. Font Adaptation

    1. Use browser developer tools, such as Chrome’s Developer Tools or Firefox’s Firebug, to simulate different device screen sizes and debug responsive Layout issues.
    2. Use online device size simulation tools or mobile device simulators, such as Responsinator or BrowserStack, to simulate web page display effects on real devices.

    Conclusion:
    Adaptation strategies and best practices of responsive layout on mobile devices can provide better user experience and accessibility. By correctly setting the viewport, using media queries, applying flexible layouts, optimizing images and fonts, and testing and debugging, you can achieve adaptive display of web pages on various screens.
