Project summary

This project can be said to be my first complete project. I have accumulated a certain amount of experience and encountered a lot of pitfalls. To summarize, here are the following points:

• Code duplication

　In actual project production, because the project contains a lot of pages, most of the areas on many pages are repeated with other pages. If you just immerse yourself in writing code at the beginning of the project without planning the project, In the end, the project code will definitely have a lot of duplicate code, which is time-consuming and unpleasant. Even if you find duplicate codes midway and start copying and pasting them to improve efficiency, these duplicate codes will still appear in each file, affecting the loading speed of the project in the browser. At the same time, if these duplicate codes need to be modified later in the project, it will also It became very troublesome.

　After the above problems, the early planning of the project is particularly important. In the planning, it is not only necessary to complete the overall layout of the project, but also to centralize the reusable code in the project for unified use and management, which is convenient Use and modification. There is a word in the front-end called "componentization", which means that code that has various functions or may be used repeatedly in the project is written into components. The most common components include carousels, pop-up windows, etc. , there are many various convenient and quick-to-use components based on JQuery on the Internet. Components are component developers who encapsulate certain functions into component constructors through js code, and component users only need to instantiate the component. Achieve the effect of using components. What we need is component-based thinking, which is the centralized management and use of repeated code.

　 If we embody component-based thinking in the project, we can achieve the following points:

• Written the basic structure that appears in most pages of the project in an HTML file. Use this HTML file as the basic template of the project's HTML code. All HTML files in subsequent development will be expanded through this template code.
• Write the css code corresponding to the HTML template file in a css file and name it "base.css". Base.css can not only put the corresponding css code in the HTML template file, but also css that has a certain number of occurrences in the project Code can be written into base.css. The code in base.css needs to have good naming conventions and friendly and readable comments.
• Good naming conventions and friendly and readable comments are not only required for the code in base.css, but also for all other codes in the project. This is a very basic and important habit as a programmer. .
• To achieve good naming conventions and friendly and readable comments, you need to have a set of feasible specifications. In team development, a set of feasible specifications is very important. If there are no standards, everyone in the team will use their own habits to write code, which will only lead to the project code being chaotic and difficult to maintain. The definition of team norms requires all members of the team to brainstorm and add rules that team members find good and acceptable to the norms. If team development is carried out under the premise of complying with specifications, team efficiency can be greatly improved and unnecessary time and communication costs can be reduced.
• Interaction

　In general project development, the main role of HTML and CSS is to produce static pages, which is the so-called cut image, and most of the interactive effects are implemented by JS, but in this project development , through the sharing of other students, I once again saw the power of CSS3. It can simulate interactive effects such as carousels, pop-up windows, click-to-switch images, etc. Although it is only a simulation, and the effect is not as perfect as that achieved by JS, it still has the desired effects, and it is simpler to implement than JS. many. In the past, these effects required JS to be achieved, but now if CSS3 and JS are combined, more and more interesting effects can be produced.
