Web front-end engineers mainly use professional knowledge and tools such as HTML, CSS, JavaScript, etc., and realize the products designed by product UI as website products, dealing with visual and interactive problems, covering PC-side and mobile-side web pages. In other words, all visual and interactive parts of user terminal products are the works of front-end engineers. So the front end is the worker closest to the user and product design.
At the same time, the front-end has to solve many interface and interaction problems, such as the compatibility of various versions in various browsers, Web standards, mobile devices, multi-terminal adaptation, etc., which will be a challenge for front-end personnel. Therefore, only through continuous learning, accumulation and creation can we bring users a better experience.
