Fix Background Gradient Color Difference between Browsers
Article Introduction：Cross-browser background gradient color repair guide
During development, I noticed a noticeable color difference between Firefox 12 and Chrome Canary 21. This obviously has to do with the way different browsers render CSS3.
Previous CSS code
background-image: -moz-linear-gradient(top, #5CB6F2, #FFF);
background-image: -webkit-gradient(linear, left top, left bottom, from(#0ae), to(#ffff));

How to make a responsive website with HTML5 and CSS3?
Article Introduction：The key to making a responsive website lies in the reasonable cooperation between HTML5 and CSS3, and the core is to make web pages display well on different devices. 1. Use HTML5 semantic tags to build clear structures, such as, , etc., to make the code easier to read and facilitate search engine crawling; 2. Use CSS3 media query to achieve multi-device adaptation, and apply different rules by detecting screen width, such as setting breakpoints such as mobile phones and tablets; 3. Use elastic layout (Flexbox or Grid) to deal with alignment and arrangement issues, and ensure that the navigation bar and other content automatically adapt to the screen; 4. Set image adaptation, use max-width:100% and srcset attributes to ensure that the image does not destroy the layout and improve the loading effect. Mastering these four key points can achieve compatibility with multiple settings

How to desaturate in Photoshop
Article Introduction：Desaturation can be achieved and optimized through a variety of methods. First, use the "Image>Adjust>Desaturation" shortcut key Shift Ctrl U to quickly decolorize but irreversible; secondly, add "Black and White Adjustment Layer" to adjust the light and darkness of each color channel to make the grayscale image more layered and suitable for stylized processing; again, use the "Hue/Saturation Adjustment Layer" to slide the saturation slider to flexibly control the overall color drop and support the addition of unified tones; finally, combine the local desaturation of the mask to highlight the key points of the picture, such as retaining the main color and erasing the background color to enhance visual design expression.

What exactly does H5 page production mean?
Article Introduction：H5 page production refers to the creation of cross-platform compatible web pages using technologies such as HTML5, CSS3 and JavaScript. Its core lies in the browser's parsing code, rendering structure, style and interactive functions. Common technologies include animation effects, responsive design, and data interaction. To avoid errors, developers should be debugged; performance optimization and best practices include image format optimization, request reduction and code specifications, etc. to improve loading speed and code quality.

Best practices for H5 page making
Article Introduction：Efficient H5 production relies on a deep understanding of tools, specifications, and performance. Specifically, it includes: proficiency in basic technologies such as HTML5, CSS3, and JavaScript. Make full use of front-end frameworks (such as Vue, React, Angular) to improve development efficiency. Build an efficient page architecture, adopt a modular design, and split the page into independent modules. Optimize code quality, use CSS preprocessor, write concise JavaScript code, and avoid abuse of global variables. Focus on performance optimization, including image compression, code compression and reducing the number of HTTP requests.

Running background scripts with HTML5 Web Workers.
Article Introduction：WebWorker is a multithreaded mechanism of HTML5, used to perform time-consuming tasks in the background without blocking the main thread. 1. It allows JavaScript operations to be put into independent threads to run, such as data encryption, image processing, etc.; 2. Worker communicates with the main thread through postMessage(), and does not support DOM operations and alert(), etc.; 3. The creation method is newWorker('worker.js'), and listens to messages in the main script and Worker script respectively; 4. Pay attention to homologous policies, memory management and compatibility issues when using them.

Improve Browser Performance With the CSS Stress Test Tool
Article Introduction：CSS3 special effects improve development efficiency, but also affect performance. This article introduces a bookmarking tool called CSS Stress Test, which can help developers identify CSS code that causes website performance problems.
The background, rounded corners, shadows, transparency and transformation of CSS3 greatly simplifies the web development process and avoids the use of image slicing, extra elements or scripts. However, these features can also have a significant impact on browser performance. A few years ago, when I first tried these technologies, I was stunned by the impact on browser performance. A simple CSS property can lead to obvious redrawing and page scrolling stuttering. In one project, I had to give up rounded corners and use pictures to solve performance problems.
Fortunately, beauty

Harnessing Web Workers for Concurrent H5 Computations
Article Introduction：WebWorkers is a mechanism in HTML5 used to execute JavaScript in background threads to avoid blocking the main thread and thus preventing UI from freezing. 1. It is suitable for scenes such as image processing, real-time audio analysis, game logic and complex computing; 2. Created through newWorker() when using it, and communicated through postMessage; 3. Notes include: the inability to access DOM and some APIs, the message delivery cost is high, and the replication overhead should be reduced; 4. Errors need to be monitored and terminate() are called in time to clean up resources; 5. For frequent DOM or lightweight tasks, alternatives such as setTimeout or WebAs can be considered

Running background scripts using HTML5 Web Workers.
Article Introduction：WebWorkers is a multi-threaded mechanism provided by HTML5, which is used to run scripts in the browser background without blocking the main thread. It allows for tasks such as complex calculations, data processing, etc. while keeping the page responsive. The steps to create and use WebWorker include: 1. Create an external JavaScript file (such as worker.js); 2. Detect browser support on the main page; 3. Instantiate Worker objects; 4. Use postMessage() to send messages; 5. Receive results through onmessage. Its limitations include inability to operate the DOM, limited communication methods, and inconvenient debugging. Applicable scenarios include mathematical calculations, timing tasks, data encryption, image processing, etc. Use We reasonably
