Brief introduction and simple Division of HTML, CSS and JavaScript

1. What is HTML (Hypertext markup language HyperTextMarkupLanguage)? HTML is a language used to describe web pages.

2. CSS (cascadingStyleSheets). The style defines how HTML elements are displayed. The syntax is: selector {property:value} (selector {attribute: value})

3. JavaScript is a scripting language, its source code does not need to be compiled before it is sent to the client for operation, but sends the character code in text format to the browser to be interpreted and run by the browser.

For a web page, HTML defines the structure of the web page, CSS describes the appearance of the web page, JavaScript sets a very classic example is that HTML is like a person's bones and organs, and CSS is a person's skin, with these two will constitute a vegetative person, plus javascript this vegetative person can respond to external stimuli, can think, exercise, can give their own cosmetic makeup (change CSS), and so on. To be a living person.

If HTML is the flesh, CSS is the skin, and Javascript is the soul. No Javascript,HTML+CSS is a vegetable, no Javascript, CSS is a disfigured vegetable.

If HTML is an architect, CSS is a decorator and Javascript is a magician.
