The operating environment of this tutorial: windows7 system, CSS3&&javascript1.8.5 version, Dell G3 computer.

CSS (Cascading Style Sheet) cascading style sheet

Presentation (presentation)-Design the presentation style of a web page, that is, "how to display relevant content"

CSS is a markup language that separates style information from web content, and we use css to define styles for each element; it is mainly used to beautify HTML pages.

The syntax is: selector {property:value} (selector {attribute: value}).

By setting the corresponding style properties, you can modify the display and location of the elements in the html document, such as color, font, font size, width and height, position, background, etc.

JS (JavaScript) is a dynamic scripting language

Behavior-controls the behavior (effect) of a web page, that is, "how the content should react to events"

The use of JavaScript code can make the foreground interactive (click events), which is often used to add a variety of dynamic functions to the web page to provide users with a more smooth and beautiful browsing effect. Usually JavaScript scripts implement their own functions by embedding them in HTML.

The difference between css and js

CSS is the web page performance, JS is the web page behavior.

CSS, cascading stylesheets, is used to modify the style of a web page, that is, to make a web page look good, while javascript is a browser-client scripting language that enables web pages to interact with people.

On the other hand, js can be used to deal with all kinds of dynamic effects of the page, which can be used to realize the interactive functions between the web page and people, such as replacing pictures, scrolling pictures, showing and hiding layers, handling shortcut keys and so on.

Client web pages usually include web content, HTML, javascript and CSS

Let me give you a popular analogy.

HTML is like a human skeleton, forming the basic framework of a web page.

CSS is like a person's skin and appearance, depicting the appearance of a web page

And javascript is like a human muscle, making the web interactive.

The content of the web page is like people's knowledge and skills.
