HTML learning

1. Introduction to HTML (just understand it)

HTML (Hyper Text Markup Language):
HTML is the abbreviation of Hyper Text Markup Language and is the most basic web page language

HTML versions:
2.0 (IETF), 3.0 (W3C), 4.01 (W3C), 5.0 (W3C)
IETF: Internet Engineering Task Force
W3C: World Wide Web Consortium

Characteristics of HTML:
is a language defined by tags. Codes are composed of tags. Codes are not case sensitive.
starts with and ends with
It consists of two parts: the header part and the body part
The head part is to add some auxiliary or attribute information to the HTML page, and the content inside it will be the most Load
first. The body part is where the page data is actually stored.

HTML tags:
Most tags have start tags and End tag . For example:

Paragraph

There are some tags that have only a single function or there is no content to be modified. They can end within the tag. For example: line break
dividing line

can also be written as

slashes can be omitted

Attributes in HTML tags:
Want To perform richer operations on the content modified by tags, use the attributes in the tags
By changing the attribute values, more effect options are added
Use "=" between the attribute name and attribute value Connection
Attribute values can use double quotes, single quotes, or no quotes. Generally, double quotes (or company regulations writing standards) are used.

2. Header tag
