Article Introduction：Client rendering (CSR) means that web page content is dynamically generated by the browser by executing JavaScript, rather than the server directly returning the complete HTML. Its core process includes: the browser first downloads the basic HTML file, then requests and executes JS code, and finally JS gets data from the API to fill the page. The advantages of CSR are fast page switching, clear front and back end separation, and suitable for high-interactive applications. But the disadvantages are that the first screen is slow loading, difficult SEO optimization, and rely on JS. Suitable for background systems, user dashboards, SPA applications; not suitable for SEO-sensitive, mass marketing or poor network environment scenarios.

Article Introduction：Optimizing key rendering paths can improve web page loading speed and user experience, and its core is to understand and optimize the entire process from code to pixels. First, the key steps include HTML parsing to generate DOM trees, CSS parsing to generate CSSOM, JavaScript execution, layout, drawing and synthesis. Delaying any step will cause page blank. Second, the optimization solutions include: compressing CSS and JS files, delaying non-essential JS, inline the key CSS on the first screen, and using async/defer attributes; again, priority is given to loading the first screen content, delaying non-element resources, and avoiding unnecessary frameworks; finally, measure and improve FCP and TTI through tools such as Lighthouse and PageSpeedInsights.

Article Introduction：HTML5 declarations must appear at the beginning of the web page, and are used to inform the browser to parse the page with the HTML5 standard to avoid entering weird mode. 1. It is not an HTML tag but a declaration. It must be located on the first line of the file and there cannot be any content in front of it. 2. It is case-insensitive, and there is no need to close the tag or add attributes; 3. When generating in dynamic language, you must ensure that there is no unnecessary interference in the output; 4. You can confirm whether it is effective by checking the source code, developer tools or online verification tools. Proper use ensures that the page renders consistently across different browsers.

Article Introduction：Core points Bookmark applets are small JavaScript code embedded in browser bookmarks that enhance the functionality of a web browser and simplify the workflow of web developers. Bookmark applets have a wide range of uses, ranging from simple navigation tasks to more complex operations, such as modifying page content, analyzing page structure, and even automating tasks on the website. While bookmark applets are generally safe and reliable, they can cause namespace conflicts. This problem can be avoided by creating anonymous functions with its own variable scope as bookmark applets. For complex bookmark applets, there is a way to bypass the length limit of bookmarks in some browsers. The actual bookmark applet implementation can be used as external .js
