Hello, everyone, this is our first lecture in HTML course. In chapter one, we're going to have a quick introduction to extremely. This is what we're going to learn in this chapter. Introduction to HTML. We're going to learn what is a markup language? And who is responsible for each team in and what are the HTML versions currently available?

What are the HTML requirements in order to start coding in HTML? What was HTML right? missiles, how we can write HTML using text editor or using a geo JSON editor? And what is meant by page is it all in site measurement? It is those and what is the future of HTML? Okay, now, let's have a quick introduction regarding HTML.

Of course, designing good pages is one of the most interesting topics nowadays. Almost everyone needs to have his own website. Well actually internet began we can see in 1986 showing 1968 and the main target for internet was to new computer computers together in order to ease the fight to scale from one machine to another, but with the growth of Internet with the growth of number of machines, number of connections. So, then we have gridlock number of operating systems, you have Linux, you have Windows Mac, whatever. So now we need very, very simple language, very easy language, in order to be able to write in my own webpage that can work on any operating system without problem, okay. And this language should be simple, no complex this.

There were many, many trials in order to satisfy these requirements. IBM, for example, created a language the coded generalized markup language in the late 60s in the last century, this language transformer to standard generalized markup language in 1986. This language was used to create a webpage, but it was very complex. Its commands was not that was not that easy. So in 1989, Tim berners Lee, he created the first real website using a language he named the Hypertext Markup Language. This is an acronym for HTML.

So of course, since that day, In 1790s, okay, this language started to generalize something to be common across the workforce. And to date, it's the main language to develop the web sites, because it's very simple. It can work on any operating system without. So let's have some definitions in order to understand what is HTML. Now, what is meant by markup language. Actually, a markup language is a language where you write its commands its data in the same language.

In contrary to programming languages, will you write your comments in a file, but when you execute, it generates it as a file, but in HTML, like you write your code And this file is the same that is displayed in your browser. Also markup language does not have any logical instructions that can make you control the program execution. You cannot skip commands or whatever. Like what happens in modern modern programming languages, maybe Aleksey Pascal, whatever. Now who's responsible for HTML, there is an organization worldwide consortium of people abbreviated as w three, see, this organization is responsible for standards of writing HTML. You can have a look at their website, www dot w three before.

For HTML, you can learn about it from this URL, and also can navigate to help An idea about the latest HTML versions. Okay, do we have versions for HTML? Yes, of course, we have many versions of HTML. Started with version 1234. Nowadays, like html5 is available. And there is also a claim for HTM in six, maybe it's not yet generalized, but we have HTML six.

Okay. Now, what are the requirements in order to start coding in HTML? As we said that HTML is simple. So the requirements is also simple. Now, what we need is a web browser. You can use Internet Explorer or Firefox, Google Chrome, whatever.

And we need Text is as simple as look at this notepad is going to write the commands for HTML. Okay, do we have other ways to write HTML? Yes, we have two ways. One is to use a text editor like Notepad or notepad even involved, whatever we can use it to write HTML. Or don't write any code in use a graphical user interface in a graphical user interface, it is actually it writes HTML code automatically. You can use your mouse you can use two bars.

Like you don't have to know that much knowledge about HTML. You can use the joy rhythm, exactly like you're using Microsoft Word. So it is much simpler. You don't have to know any commands. And of course, it reduces the time. So do we still need to learn HTML?

Yes. Why? If you have some mistakes, for example, well, many times you need to debug inside the code itself in order to know what's wrong. If your page does not display correctly, then of course, you need to debug in HTML. Second, if you're going to be a web developer, using server side programming technologies, like ASP or Lovaas over to IE, PHP, or whatever Will you need to have quite good knowledge about HTML, because HTML code is not written statically it's written and generated dynamically at runtime. So many times you need to debug in HTML code.

You have many editors, like Dreamweaver, of course. It was Macromedia product now with Adobe photo. You can use Microsoft front page or today go live or home site, whatever editor you're using, you can use any one of them, most of them or like similar. Now, graphical user interface editors can be divided into two types, page editors and site management editors. In page editors, well, you design each page individually. You cannot lean or have a project that has all files in them.

One one. We used to have Netscape, Netscape composer and Microsoft on the front page, except for us. Of course, these became obsolete or you can use sight measurement at the dose. Okay, now, it's the responsibility for organizing files, images, whatever is, is the responsibility of a wide page editor. You have to organize your files, the way it's your responsibility, but inside editors or site management editors, yeah, it can match. If something exists, like you have Adobe Dreamweaver, the way home site, Microsoft comm page and IBM will disappear.

So as we said, like is he ended up sleep. We were discussing that we have some view on it, it was almost you don't have to write in HTML anymore, but as we said, in order to develop and in order To know how we can use it is very important. Sometimes I can bring some code from the internet, or whatever. Okay, in this case, we'll write it exactly. I need to debug. And I need to know where to exactly.

Put my coat. So this is very important to understand the structure of HTML. Also, like if you're going to use script language like JavaScript, or whatever, well, of course, you will need to know also about HTML because you're going to write manually many things. Okay, guys, in this chapter, it was very quick introduction regarding HTML. All I need from you right now is to have simple text editor like notepad where we're going to use it in order to write our first HTML page. This is the end of Chapter one.

See you guys in chapter two. Thank you
