The front-end is the front-end part of the website, which runs on the PC, mobile and other browsers displayed to users the web pages. Most back-end developers are engaged in building the actual logic behind the working application. The front and back ends need to cooperate with each other to complete a project together.
What is front-end development?
1. Front-end concept
The front-end is the front-end part of the website, which runs on the PC, mobile and other browsers displayed to users to browse the web pages. With the development of Internet technology, the application of HTML5, CSS3, front-end framework, cross-platform responsive web design can adapt to various screen resolutions, perfect dynamic design, and bring extremely high user experience to users.
2. Front-end features
Refers to Hypertext Markup Language, which is also the most commonly used language on our web pages. After several versions of development, it has been developed to version 5.0. Thanks to the standards and specifications established by W3C, it has been generally upgraded When it comes to XHTML, XHTML refers to Extensible Hypertext Markup Language. XHTML became a 3C standard on the 126th of 2000. It is a more highly updated HTML code. The goal of XHTML is to demonstrate HTML. XHTML is almost the same as HTML 4.01. XHTML is HTML that has been redefined as an XML application and is a W3C standard. W3C defines XHTML as the latest HTML version. All new browsers support XHTML.
Cascading Style Sheet is abbreviated as “CSS”, usually also called “Style Sheet”, which is used for web page style design. For example, if you want the link word to be blue when it is not clicked, and the word becomes red and underlined when the mouse is moved up, this is a style. By setting up a style sheet, you can uniformly control the display attributes of each mark in HTML. Cascading style sheets can make people more effective in controlling the appearance of web pages. Using cascading style sheets, you can expand the ability to precisely specify the position and appearance of web page elements and create special effects.
What is the backend?
1. Back-end concept
Most back-end developers are engaged in building the actual logic behind the application they are working on. Front-end developers build the user interface, while back-end developers write code to make it work. Back-end developers write code that makes the buttons work, by pointing out which data is extracted from the database and passing it back to the front-end. Back-end developers may also participate heavily in the system architecture, deciding how to organize the logic of the system so that it can be maintained and operated normally.
May participate in building a framework or system architecture to make it easier to write programs. Back-end developers spend more time implementing algorithms and solving problems than front-end developers. Usually front-end development work is more about creating a user interface and related content, rather than implementing the actual business logic to make the application work.
2. Main technologies for back-end development
Front-end developers need to know a series of tools for creating user interfaces, while back-end developers usually use a completely different set of tools and skills in order to complete their work efficiently. An important skill required by back-end developers has to do with SQL and databases. Most back-end systems need to connect to a database that stores application data.
The usual job of back-end developers is to write, read, and process data from databases or other data sources, so it is very important to have skills such as SQL. Back-end developers-at least for web development-also need to be good at the server-side language of the technology stack they are using.
Back-end developers need to know more about the application architecture, because in most cases, back-end developers need to build the architecture and internal design of the application. A good back-end developer has to know how to use various frameworks and libraries, how to integrate them into applications, and how to structure code and business logic in a way that makes the system easier to maintain.
The front-end user-visible interface. The front-end page of the website is the page development of the web page. The front-end work content is to design the renderings designed by the art into a web page that the browser can run, and cooperate with the back-end to make the data display and interaction of the web page visible. The content of the work; the back-end refers to the things that users can’t see, usually the data interaction with the front-end engineers and the saving and reading of website data. Relatively speaking, the back-end involves more logic codes than the front-end. The end considers the realization of the underlying business logic, the stability and performance of the platform, etc.
The above is the specific difference between the front end and the back end. I believe that through the sharing of this article, everyone has a general understanding of the front-end and back-end.
