What do web front-end development engineers need to learn?
HTML, CSS and JavaScript.
Html is content, css is presentation and javascript is behavior. The threshold for front-end development is actually very low. Compared with the learning curve of server-side language, the learning curve of front-end development is fast first and then slow. Therefore, for people engaged in IT work, front-end development is a good starting point. It is precisely because of this that there are many self-taught "talents" in the front-end development field. Html is the most basic, and now it is popular to design html5. Learn the layout of the web page first. Css is used to beautify html pages and provide layout and format for the pages. Finally, learn javascript. If you spend your time watching movies and TV series every day studying, I think it is no problem to get started in one week.
