This article mainly introduces the web front-end web page development is inseparable from the three elements of the relevant knowledge, the content is detailed and easy to understand, the operation is simple and fast, with a certain reference value, I believe that you can read this web front-end web development without what the three elements of the article will have a harvest, let's take a look at it.

HTML, Hypertext markup language, an application under the standard general markup language. It includes the "head" part (English: Head) and the "body" part (English: Body), in which the "head" part provides information about the web page, and the "body" part provides the specific content of the web page.

CSS, cascading style sheet, is a computer language used to represent file styles such as HTML (an application of Standard Generalized markup language) or XML (a subset of Standard Generalized markup language).

JavaScript, a literal scripting language, is a dynamically typed, weakly typed, prototype-based language with built-in support for types. It is widely used in Web application development, and is often used to add a variety of dynamic functions to web pages to provide users with a more smooth and beautiful browsing effect. Usually JavaScript scripts implement their own functions by embedding them in HTML.

With the rapid development of the Internet era and the change of enterprise requirements, the three elements of front-end development technology have evolved into today's HTML5, CSS3 and jQuery. As a result, the contents of many introductory courses on Web front-end development have also been adjusted to some extent.

HTML5 is the fifth major modification of hypertext markup language. It introduces new features based on HTML, which can really change the way users interact with documents, which mainly include: "the new parsing rules enhance flexibility, new attributes, and eliminate outdated or redundant attributes." Drag-and-drop capabilities from one HTML5 document to another, offline editing, enhancements to messaging, detailed parsing rules, multi-purpose Internet mail extensions and protocol handler registration, common standards (WebSQL) for storing data in SQL databases, etc. "

CSS3 is the upgraded version of CSS (cascading style sheet) technology, which mainly includes box model, list module, hyperlink mode, language module, background and frame, text special effects, multi-column layout and other modules. CSS can not only modify the web page statically, but also format the elements of the web page dynamically with various scripting languages.

JQuery, a fast and concise JavaScript framework, encapsulates the functional code commonly used in JavaScript, provides a simple JavaScript design pattern, and optimizes HTML document operation, event handling, animation design and Ajax interaction. JQuery is compatible with all kinds of mainstream browsers, and the core features can be summarized as follows: unique chain syntax and short and clear multi-function interface; efficient and flexible css selector, which can be extended to CSS selector; convenient plug-in extension mechanism and rich plug-ins.
