It involves everything that users can see, touch and experience; that is, the web front-end includes the structure of the web page, the visual representation of the web's appearance, and the implementation of interaction at the web level. The web front-end is primarily about coding and building the visible stuff, the interface that users interact with, concentrated in a web application or website.

What is the Web front-end
The Web front-end is the web page displayed to the user, that is, the front-end part of the website.
The web front-end, also known as the "client", is about the visual aspects of the website that users can see and experience, that is, everything the user sees and what the web browser displays, involving what the user can see , everything you touch and experience; that is, the web front-end includes the structure of the web page, the visual appearance of the web, and the implementation of interaction at the web level.
The web front-end evolved from web page production, and its name has obvious characteristics of the times. In the evolution of the Internet, web page production is a product of the Web 1.0 era. The main content of early websites was static, mainly pictures and text, and users' behavior when using the website was mainly browsing. With the development of Internet technology and the application of HTML5 and CSS3, modern web pages are more beautiful, have significant interactive effects, and are more powerful.
The web front-end is mainly aimed at coding and building visible things, that is, the interface for users to interact with, concentrated in a web application or website. It also includes the development of mobile applications and the people responsible for creating the layout or architecture of these types of applications are front-end developers.
The web is the Global Wide Area Network, also known as the World Wide Web. It is a global, dynamically interactive, cross-platform distributed graphical information system based on hypertext and HTTP. It is a network service built on the Internet. It provides a graphical, easy-to-access and intuitive interface for viewers to find and browse information on the Internet. The documents and hyperlinks organize the information nodes on the Internet into an interconnected system. network structure.
The challenge with front-end web programming is that the tools and technologies used to implement front-end pages change rapidly, so engineers need to constantly pay attention to how the industry is developing (such as ECMAScript 6).
The purpose of designing web pages is to ensure that when users open the site, the information is presented in an easy-to-read and relevant form. The problem that comes with this is that users now use a large number of devices to access the web, and these devices have different screen sizes and resolutions.
So designers need to pay attention to these aspects when designing web pages. They need to ensure that their web pages display correctly in different browsers, different operating systems, and different devices, which requires careful planning on the engineer's end.
The job of the front-end developer
The job of the front-end developer is to implement visual and interactive elements, these functions are to help their applications To attract more users to a program or website, web applications are usually supported by back-end developers who are responsible for creating the server side of the application logic, and the rest of the integrated content is partly done by front-end developers. Responsibilities often include converting UI/UX wireframes into actual code, producing better-looking interfaces.
Skills required for front-end developers
Front-end developers must be experts in HTML, CSS and Javascript or be proficient in some other Jquery types The writing of frameworks (such as Angular JS nodeJs, etc.). In addition to understanding and studying these frameworks and techniques, you should also be very proficient in the pre-processing part.
Front-end developers need to know how to write logic or code and be able to make the project work in a business environment. Therefore, front-end developers should be able to use version control tools such as GIT. Likewise, he should also be proficient in Continous integration and continuous deployment tools like TeamCity or Jenkins, these are important for developers as they help in managing and automating builds which play a vital role when it comes to development effect.
Why do we need front-end developers?
The front-end is the person responsible for providing visual effects to users. Without a front-end, users would have no idea what to do when looking at numerous APIs. Imagine if you create a website about selling clothes, but users cannot view pictures of clothes, then who will come to this website again? Ordinary users do not have professional skills, so they need front-end developers to make everything clear and straightforward.

Real-time protection against face-blocking barrages on the web (based on machine learning)
Jun 10, 2023 pm 01:03 PM
Face-blocking barrage means that a large number of barrages float by without blocking the person in the video, making it look like they are floating from behind the person. Machine learning has been popular for several years, but many people don’t know that these capabilities can also be run in browsers. This article introduces the practical optimization process in video barrages. At the end of the article, it lists some applicable scenarios for this solution, hoping to open it up. Some ideas. mediapipeDemo (https://google.github.io/mediapipe/) demonstrates the mainstream implementation principle of face-blocking barrage on-demand up upload. The server background calculation extracts the portrait area in the video screen, and converts it into svg storage while the client plays the video. Download svg from the server and combine it with barrage, portrait
