We’re gonna talk about Sir Tim Berners-Lee. He is the first web developer.
He invented the World Wide Web. But let’s first make a distinction between the World Wide Web and the Internet. If you wanna go have a history lesson about the Internet, go to this website: https://www.vox.com/a/internet-maps. It’s a really informative website.
The Internet started off with the ARPANET in 1969. It was just a small project that connected some of the universities such as UTAH and UCLA.
And then between the 70’s and 80’s, it kept growing.
And then here was the first Internet backbone.
There was one problem that they had–they needed a way to share documents. Up until the World Wide Web, the Internet was already there. But it was really hard for computers to communicate with each other with just the Internet.
We can think of this as oral languages. You know, people from all over the world communicate to each other but it’s like doing it without phones or any other communication line. And gosh, you can send files with the Internet only, but it was almost impossible.
The first browser, the first server, and the first website
This was the first website, ever! It’s fortunate that they still have it until today.
You can see this website here: http://info.cern.ch/hypertext/WWW/TheProject.html
It was already running since 1991. For now, let’s talk about how all these was possible.
HTML, as you may already know, means HyperText Markup Language. We use this just to write text. These things on websites that we call hyperlinks that can take us to the other parts of the website. As an example, click on that hypermedia and it will take us here:
Now you can click on the links and see these:
Of course, you can always go back here:
By the way, that’s what we had back in 1991. Finally, we had a way to share documents. Additionally, these links can take us to another website, another file, etc. I know that it’s not much, but in their time, this was the most beautiful website they’ve ever seen in their life. With that reason, the next things come into being.
This means Cascading Style Sheets. In the first place, Hakon Wium Lie proposed the concept of CSS while working with Tim-Berner Lee in 1994. The first CSS was officially, released on December 17, 1996.
CSS was responsible with the view and the layout of the website. It was in charge of making a website pretty. As an example the jw.org/en:
So beautifully laid out, isn’t it?
So, you saw that it is a powerful scripting language, widely used for controlling web page behavior and used to make a website interactive.1allowing a two-way flow of information between a computer and a computer-user; responding to a user’s input.
Let’s get back here at this page:
Press right click and then click on Inspect:
Here on the HTML code, click on the <body>:
With that in place, click on the element.style below the Style:
And then type color : darkgoldenrod:
As you can see, it changed the text color from black to gold. Now let’s do something with the background color. Let’s add background-color : blanchedalmond:
Now press ENTER:
Why are there different web browsers?
We have these different kinds of servers:
I’m sure that you have seen these different web browsers. These are just some of the many other web browsers like Opera, Microsoft Edge, Vivaldi, Brave, UC Browser, and a whole lot more! But you may have wondered as well: “Can’t we just have one kind of web browser?” Nonetheless, here’s the thing, each one of them is owned by its own company.
Above everything else that we’ve just learned, take these new knowledge with you as you go make your own applications and your own websites. Now, looks like you’re ready to be a web developer. Why don’t you try out the course on Learn Python? You can have a background with computers at the first lesson. But if you want to get straight to learning on how to code using Python, start on Lesson 3.
But if you don’t want to code for now, you can always read this article: How does The Internet Work?
