Everyone starts and ends from beginning to end. Now, I have a good experience, but I don't know how many storms there are in front of me, or how many scenery there are in front of me ,,,
The future is a person's dream. The beginning is a person's frontier. To have a good dream, you must have a spirit of commitment. Everyone is different. You have your thoughts, and he has his opinions, you don't have to worry about everyone's difference,
It should be different for everyone.
The following is my computer learning experience. As a beginner, I have no experience, but I have a start. Now I have learned CSS, I feel that the road is getting increasingly uneven, which is also the charm of this technology,
Web Application Development Principles
1: Evolution of enterprise application computing, centralized computing mode for host/mute terminals, and client/server computing mode,
2: Working Principle of B/S structured Web applications,
(1) webpage: (when we open the browser to browse the webpage, the content of the webpage document is displayed in the browser) for example: When we enter an application system, A similar user logon interface is usually provided.
(2): webpage content: (the purpose of creating a webpage is to provide information to users who browse the webpage)
(3): The structure of the webpage: (document title, section, and list. This is something similar to the title, author, chapter, section, paragraph, and list. we name it as a structure. Structure makes the content more logical and easy to use. On the webpage,
The structure definition uses the HTML language ).
(4): Web server: (after the web page is developed, it needs to be uploaded to the server for Internet users to browse. on the Web, the computer that stores the web page we wrote is called a Web server .)
(5): Web Browser: (on any computer connected to the Web, we can run an application called web browser to browse webpages stored on the Web server)
(6): HTTP Protocol: (Hypertext Transfer protocol HTTP)
(7): Webpage Classification: (based on the web server's webpage resolution method, we can divide it into three types: static webpage, client dynamic webpage, and Server Dynamic Webpage)
XHTML
1: The XHTML document consists of elements that define how text and graphics are displayed in the browser and tell the web browser how to display pages.
2: The XHTML element is defined using the XHTML tag, and each tag appears in a pair of angle brackets (<>. Tags usually appear in pairs. The first tag defines the starting point of the tag, which is called the "start tag". The second tag defines the end of the tag,
It is called the end mark ". The text between the start tag and the end tag is called the element content.
3: The tag has attributes, which provide additional information about the XHTML elements on the page.
4: the overall structure of the XHTML document is composed of three document-level tags: <HTML>, 5: XHTML contains several block-level tags to limit and format paragraph text. These tags include: <p>, 6. Mark the XHTML used to create a hyperlink as <A>.
7. Mark the XHTML of the created image as .
8: The XHTML for creating multimedia information is marked as <Object>.
9: The xhtml of the table Information created on the webpage is marked as <Table>.

XHTML form
1: HTML form tags provide a set of elements and attributes for creating forms and collecting webpage visitor information.
2: HTML form markup elements and attributes can be divided into two types: defining the overall structure of the form to let the browser know how to process the elements of the form data: creating the elements of the input object.
3: create a form structure and mark it as <form> and </form>.
4: In the <form> tag, we must use two key attributes: "action" and "method ".
5: HTML supports multiple input controls, including text boxes, single-dataset, images, and:. There are three elements used to create an HTML input control: <input> elements use the type attribute to define different controls, including text and password fields, check boxes,
Single button, submit and reset button, file, hide domain and image; <SELECT> and <option> use both to create a drop-down list; <textarea> Create a text box with multiple lines of input.
