Now let’s make the simplest web application: use a browser to display Hello World! .
Let’s first look at what a browser is: A browser refers to a software that can display the content of HTML files (an application of Standard Universal Markup Language) on a web server or file system, and allows users to interact with these files. .
We can see that the browser can recognize html files. Let's create a new html file.
1. Right-click to create a new text document
2. Rename and change the file extension to html
3. Open the file with text, write hello world on the first line and save it
4. Then open it with a browser. ok, hello world is displayed in the browser.
This can be considered a simple web application. The function of this application is to display the English words hello world.
