When teaching the first lesson, the first concept that I need to explain to everyone is: what we are learning is a language, not a compilation tool, so we must get used to ignoring the concept of compilation tools when writing programs, because only Only by ignoring the compilation tools can we truly understand the essence of a language and truly understand how a language is learned. This process is very important.
Many times when we start a language, we first develop a compiler or an integrated development environment for this language. We think that after doing this, we can fully master a language. In fact, this is not the case. Many people just learn it. It’s just a superficial knowledge. If it is actually applied to project development, it will be vulnerable. Therefore, before teaching this course, I strongly recommend that you use txt notepad or Microsoft word document to type the code first, and then become familiar with it. Understand what each code is used for, so that you can selectively use a compiler with high development efficiency after mastering the language.
Today is the first lesson. Let’s first look at a code:
//Because html is a hypertext markup language, but it is also based on xml , so what you can see here is that the version of xml given is 1.0; and it also shows that its standard code is UTF-8;
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
//The thing above that looks like a URL is not a URL, but a namespace. This will be introduced slowly in future studies, but the main html tag here is like a big The house has everything wrapped up in it.
In the beginning, Time created the HyperText Markup Language.The Internet was without form and void,and text was upon the face of the monitor and the hands of Tim were moving over the face of the keyboard.And Tim said,Let there be links;and there were links.And Tim saw that the links were good;and Time separeted the links from the text.Time called the links Anchors,and the text He called Other Stuff.And the whole thing together was the first Web Page.
tag in the program is used to contain a piece of text. In this example, this tag is not necessary because there is only one paragraph. If this web page contains many paragraphs, this tag will be very important.
Now that the basic narration is over, this is the end of the first lesson. See you in the next lesson!
