Web learning HTML

Before introducing HTML, I would like to talk about the Web, the Internet that we often talk about, and the web page is a webpage or a document. Where does this document come from? Then, HTML will be released.

I. Web and HTML

Web is a general term for the internet. Wbe is intended to mean spider Web or Web. in Web design, we call it Web page. It is now widely used in the network, Internet and other technical fields. Its forms include hypertext hypermedia and HTTP ).

HTML (Hypertext Markup Language): a Hypertext Markup Language used to compile web pages.

The essence of a Web page is the Super Text Markup Language. By combining other Web technologies (such as scripting language, public gateway interface, and components), you can create powerful Web pages. Therefore, the Super Text Markup Language is the foundation of Web programming, that is, the World Wide Web is based on hypertext. Hypertext markup language is called hypertext markup language because it contains so-called "HYPERLINK" points.

Ii. How Web works

1. Enter the URL: When you want to access a web page or other network resources on the World Wide Web, generally, you need to first type the uniform resource Locator (UniformResource Locator) that you want to access the web page on your browser, which is what we usually call the URL, or you can use a hyperlink to link to the webpage or network resource.

2. Resolve the website: the server name section of the URL is followed by the Domain Name System's Internet database distributed around the world to resolve the URL you entered, determine the IP address to access based on the resolution result ). The next step is to send an HTTP request to the server working at that IP address for the webpage to be accessed. In general, HTML text, images, and all other files that make up the web page will soon be sent to users one by one.

3. browser rendering: The next job of the Web browser is to display the content described in HTML, CSS, and other accepted files, including images, links, and other necessary resources to users. These constitute the web page you see.

3. Basic HTML knowledge

For the study of HTML, I first took control from both macro and micro perspectives. From a macro perspective, HTML knowledge includes documents, tags, tables, and hyperlinks. At the micro level, some basic elements of a Web page are a combination of null elements, content elements, and familiar elements.

Tags can be used for control paragraphs or for control text. Tables are divided into tables, lists (list of numbers, graphics), and forms. The form function is very powerful. It can control the type of controls on the webpage.Label type property control.

Some of the knowledge of HTML has been used in the NIU news publishing system, and now it has finally become a resonance.
