How to program web front-end
With the rapid development of the Internet, the status of Web front-end development is becoming more and more important. Web front-end development refers to the process of converting pages designed by designers or interface designers into interactive web pages. In layman's terms, it is the front-end production of a website, including technologies such as HTML, CSS, and JavaScript. This article will introduce some basic knowledge and programming skills of Web front-end development.
1. Basic knowledge of Web front-end development
- Basic concepts of web pages
A web page refers to a document that is interpreted and executed by a web browser, including text , images, audio, video and other elements. The structure of a web page is defined by HTML, the style is defined by CSS, and the interaction is implemented by JavaScript. Understanding the basic concepts of web pages is crucial for web front-end programming.
- HTML
HTML is the abbreviation of HyperText Markup Language, which is used to define the structure of web pages and is the basis for Web front-end development. Learning HTML requires mastering the basic syntax of HTML tags, common tags and their attributes.
- CSS
CSS is the abbreviation of Cascading Style Sheets, which is used to define the style of web pages and can control the layout, fonts, colors, sizes, etc. of web pages. Learning CSS requires mastering knowledge of CSS selectors, style rules, box models, floating, positioning, etc.
- JavaScript
JavaScript is an object-oriented programming language used to achieve interactive effects on web pages. Learning JavaScript requires mastering basic syntax, variables, functions, objects, events, etc.
2. Web front-end programming skills
- Selection of editor
For Web front-end development, it is very important to choose a good editor. Commonly used editors include Sublime Text, Visual Studio Code, Atom, etc. These editors have rich features, such as code highlighting, auto-completion, code snippets, etc., which can improve programming efficiency.
- Mastering common tools
Web front-end development requires the use of some common tools, such as Git, npm, Webpack, etc. Git is a tool for version control that can manage versions and branches of code. npm is the package manager for Node.js, used to install and manage packages. Webpack is a tool for packaging and managing modules. It can package multiple files into one file and reduce the number of http requests.
- Following specifications
Following specifications is one of the most basic elements of Web front-end work. Follow the standards of HTML, CSS and JavaScript, and pay attention to the readability and maintainability of the code. At the same time, we should try to reduce the loading time of the page and improve the user experience.
- Flexible use of frameworks
Frameworks are commonly used tools in Web front-end development, which can improve development efficiency and avoid duplication of work. For example, the Bootstrap framework can quickly build a responsive website, and the Vue.js framework can easily implement component development. However, use the framework flexibly and do not rely too much on it.
- Continuous learning and practice
Web front-end development is a process of continuous learning and practice. Pay attention to the development of new technologies and constantly improve your skills and abilities. At the same time, we must accumulate project experience and continuously improve our practical capabilities.
Conclusion
Web front-end development is a field that is constantly developing and changing and requires continuous learning and practice. Only by mastering basic knowledge and programming skills, choosing good editors and tools, following specifications, using frameworks flexibly, and continuing to learn and practice can you become an excellent web front-end developer.

Event delegation is a technique that uses the event bubble mechanism to hand over the event processing of child elements to the parent element. It reduces memory consumption and supports dynamic content management by binding listeners on parent elements. The specific steps are: 1. Binding event listeners to the parent container; 2. Use event.target to determine the child elements that trigger the event in the callback function; 3. Execute the corresponding logic based on the child elements. Its advantages include improving performance, simplifying code maintenance and adapting to dynamically added elements. When using it, you should pay attention to event bubble restrictions, avoid excessive centralized monitoring, and reasonably select parent elements.

The core of optimizing front-end build time is to reduce redundant work, improve processing efficiency, utilize caches and select efficient tools. 1. Use TreeShaking and code segmentation reasonably to ensure that it is introduced on demand and dynamic import reduces the packaging volume; 2. Reduce unnecessary loader processing, exclude node_modules, upgrade loaders and relax the scope of Babel translation; 3. Use the caching mechanism to speed up repeated construction, enable Webpack cache, CI cache and use offline installation; 4. Upgrade toolchain, such as using Vite, esbuild or Rollup to improve the construction speed, although there is migration cost, it has significant effect.

When using OAuth 2.0, PKCE authorization code process should be adopted instead of implicit process, avoid storing tokens in localStorage on the front end, priority is given to processing refresh tokens through the back end, and secure integration is achieved using a trusted authentication library to ensure the security of front-end applications.
