Software development process under the web_html/css_WEB-ITnose

The company is looking for someone to develop a series of software for the web. Those who have done embedded work before are not particularly knowledgeable about this aspect.
What if we want to design the software first and then have people code it to implement it?
What is the development process for web-based software?
Thank you

The big process is as above, everyone who has basically done the project knows it
General web development
The front-end and backend are developed at the same time. The front-end must confirm that all the controls in the form are It cannot be less, so that it will not affect the backend very much
The backend only considers the format of receiving and returning data, and the front end considers how to display it
It is the best choice to be able to separate data and pages, so that it is better for modification, maintenance and projects There are benefits to upgrading
If it is a non-web client, it should be easier

Now the main thing is that we have some ideas that we want to express through some modeling tools. I don’t know if it is similar to ordinary software. Can we also use tools like UML to design, or are there other tools and methods that can be used? Thank you

UML is not used to design front-end pages.

The process is: first determine the requirements, produce a DEMO diagram according to the requirements, and the front-end and program will divide the work according to the requirements. The front-end makes graphics, and the program builds the database and underlying code. It is best to use a framework like MVC to build applications. It can be used by every WEB program.
