Today, I would like to share with you the relevant knowledge of what is the difference between HTML, CSS and JavaScript. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

1 、 HTML-Hypertext Markup Language

Hypertext markup language. It marks each part of the web page to be displayed by marking symbols. The web page file itself is a kind of text file, and by adding markers to the text file, you can tell the browser how to display the contents (such as how to deal with the text, how to arrange the picture, how to display the picture, etc.). The browser reads the web page file sequentially, and then interprets and displays the contents of its tags according to the tags:

HTML

HTML text contains the so-called "link point" HTML uses hyperlinks to organize text information from different spaces together. Generally speaking, HTML is a language that integrates the structure of web pages and the display of content.

2 、 CSS-Cascading Style Sheet

Cascading style sheets. Is a markup language that separates style information from web content.

We use CSS to define styles for each HTML element, which can also be used for multiple interfaces. When you make a global update, you only need to modify the style. Body {border: 1px solid # 000; font-size: 14px;}

To put it bluntly, CSS is the language for setting the properties of HTML elements on a web page.

3 、 JavaScript

It was very depressing at first. Why is its name so similar to Java?

This is a typical marketing success, and its promotion success is also borrowed from the east wind of Java. When Microsoft began to realize that Javascript was becoming popular among Web developers, Microsoft was consistent and established its own scripting language, JScript.

Javascript is an object-based (Object) and event-driven (Event Driven) scripting language with security performance. The purpose of using it is to link multiple objects in a Web page and interact with Web customers together with HTML Hypertext markup language and Java scripting language (Java Mini Program). For example, you can set the mouse over effect, validate forms on the client side, create custom HTML pages, display warning boxes, set cookie, and so on.

Function jsHello {alert ('Hello Worldwide');}

Embed the code in the HTML language, and it will pop up a "Hello World" dialog box when it loads.
