The basic elements that make up a Web page

Web page

2.1 Topics (title)
The title element is the only element in the header of the file that must appear, and it can only appear in the file header. The format of the title element is:
file Title
Title The title of the HTML file, is a summary of the contents of the file. A good topic should enable the reader to determine the approximate content of the document. The title of the file is not normally displayed in the text window, and the name of the window appears. In addition to identifying a window, title is used as either a bookmark or a default filename when a homepage is saved to bookmarks or files.
There is no limit to the length of the title, but the long title will cause the line to be broken, and in general it should not be longer than 64 characters. Because the role of title is to mark the contents of the file, so too short title is also undesirable, such as: Introduction This topic, the reader can not judge according to it what this article describes. A good example of this is:
a Introduction to HTML 2.0
Other elements, such as

This is a searchable index. Enter search keywords: ,, can also appear in the header element. These elements are not required, and are not commonly used. The use of these elements and their meanings can be referenced in the literature.
The following is one of the simplest HTML files

This is the My-i-i-HTML file.

§2.2 title (HN)
There are 6 kinds of heading elements, H1, H2,... h6, used to represent various topics in the article. The smaller the title number, the larger the font. In general, the browser explains the title as follows:
H1 bold, oversize font, centered, with two lines of blank line up and down.
H2 bold, large font, up and down each one to two lines of blank lines
H3 Bold (italic), large font, the left side of the miniature into, up and down empty lines
H4 bold, plain font, more indented than H3, a blank line above
H5 Bold (italic), same indent as H4, top blank line
H6 bold, with the same indentation as the body, a blank line above
Netscape 2.0 is the explanation for HN, all boldface, font is getting smaller.
　
HN can have alignment attributes, align=#, #表示left title Center left center title right
Example:

chapter 2

The example of HN and its output are given below:

§2.3 Section

HTML browser is based on the window, the user can change the size of the display area at any time, so the HTML will be multiple spaces and carriage return equivalent to a space, which is different from most word processors. The fragmentation of HTML is entirely dependent on the segmented element

. For example, the following two sections of source files have the same output.

this is a level two Heading

Paragraphy one

paragraph two

... ... ... ... ... ... ... ... ... ...

this is a level two heading

Paragraph one

Paragraph two

can also have a variety of properties, the more commonly used properties are:
aligh=# #可以是left, Center,right, whose meaning is the same as above.
Example

this is a centered paragraph

when there is a graphic in the HTML file, the graphic may occupy one end of the window, and there may be a larger space around the graphic. At this point,

with no clear attribute may cause the contents of the article to appear in that blank area. To ensure that the next paragraph appears below the graphic, you can use the clear property. The Clear property means:
Clear=left The next section shows a blank area at the left edge
Clear=right The next section shows a blank area at the right edge.
Clear=all There's no other content on either side of the next section.
