After several days of thinking and continuous practice, when making a specific work, you should design the model of the development project and the functions to be realized before starting.
I feel that I can’t think about it while doing it. Otherwise, you will always feel dissatisfied with the style you have implemented during the process, and you will constantly modify it and keep trying. At this time, you will feel helpless and not only unable to make the work better The completion of it will also make you become impetuous. leading to giving up midway.
Take the page I made as an example! In the beginning, I just wanted to make a simple web page, but in the process of doing it, I felt that I wanted to improve the functions of the following pages and beautify the page. However, it caused many difficulties later and I couldn't proceed for a while. Anyway, there are still difficulties. I hope everyone can work together to improve this webpage and communicate with each other. 1 <!DOCTYPE html> 2 <html "lang="zh-CN""> 3 <head> 4 <meta charset="UTF-8"> 5 <title>visvitortitle> 6 <meta
