What does web mean in web front-end

In a broad sense, web refers to the World Wide Web, which is the general term for a series of technologies.

It was probably in the last century Around the 1990s, a person named Tim Berners-Lee hoped that documents could be shared between networked computers. In order to achieve this goal, they designed it like this:

requires a special format document : That is, in order to facilitate positioning of hypertext documents, each document or file must have an indentifier that can uniquely identify them: that is, when the uri transmits the document, it must follow a rule: that is, HTTP Hypertext Transfer Protocol, client (front-end) How to request the server (backend), how to respond, etc.

The World Wide Web was formed in this way. This is the web in a broad sense: a general term for a series of technologies

The specific web refers to the use of tags A file written in a language such as html is called a hypertext document (page). Whether it is generated using a dynamic scripting language or written in a static language, it is collectively referred to as web

Web, that is, Web front-end development , is the process of creating a front-end interface such as a Web page or app to present it to users. It uses HTML, CSS, JavaScript, and various derived technologies, frameworks, and solutions to realize user interface interaction of Internet products.

So what are the HTML, CSS, and JavaScript that must be learned to learn the Web? In simple terms, it can be understood like this:

1. HTML: HTML is called hypertext markup language. It is an iconic language. HTML5 is the specification for HTML, the core language in the Web.

2. CSS: It is a computer language used to express file styles such as HTML or XML. CSS3 is an upgraded version of CSS technology.

3. JavaScript: It is a lightweight, interpreted or just-in-time compiled high-level programming language with function priority. JavaScript is a prototype-based programming, multi-paradigm dynamic scripting language.

In web design, we call it web page. Now it is widely translated into technical fields such as network and Internet. It manifests in three forms, namely hypertext, hypermedia, hypertext transfer protocol (HTTP), etc.

Expand knowledge

The web front-end is divided into web designers, web artists, and web front-end development engineers. First of all, web designers are responsible for the architecture of web pages. , colors and the overall page code of the website. Web page art is only responsible for UI things, such as whether the website is beautiful. Web front-end development engineers are responsible for interaction design.

A good Web front-end development engineer must have both breadth and depth in the knowledge system, so it is difficult for many large companies to recruit ideal front-end development engineers even if they offer high salaries. So how to systematically learn practical web front-end technologies for enterprises? The focus now is not on explaining the technology, but more on explaining the skills. Technology is not black and white, there are only right and wrong, and skills are a matter of opinion.

The scripting technologies that the web front-end needs to master include JavaScript, DIV, CSS, the most popular page building technologies, ajax and jquery, and simple back-end programs. For the back-end, the languages ​​available for development include asp, php, jsp, and .NET. The construction environments for these back-end development languages ​​are different. Specifically, if you want to learn, it depends on whether you want to work on the front-end part or the back-end program part. Back-end development can be converted to software development if certain conditions are met. But you need to have a certain language foundation, similar to Java language. C# etc. The key is to look at your interests and hobbies.
