This paragraph introduces the three core languages of the internet: HTML, CSS, and JavaScript. It likens them to the three languages of Belgium, emphasizing their importance and interdependence in web development. HTML is described as 'The Builder,' responsible for the structure and content of a webpage. CSS is 'The Artist,' adding style and aesthetics, while JavaScript is 'The Wizard,' enabling interactive elements. The paragraph also touches on the evolution of these languages and the role of web browsers in translating them into visual web pages, highlighting the differences in browser rendering and the ongoing development of HTML5 standards.

Keywords

💡HTML

HTML, or Hypertext Markup Language, is the backbone of web development, defining the structure and content of web pages. In the video, it is referred to as 'The Builder', emphasizing its role in laying the foundation for a website's text, images, and links. The script illustrates that without CSS and JavaScript, an HTML-only page would lack the visual appeal and interactivity that modern users expect.

JavaScript is a scripting language that enables interactive web pages and is referred to as 'The Wizard' in the script. It adds interactivity and dynamic content to websites, such as pop-up messages and auto-complete features. The script notes that JavaScript has evolved from simple popups to animating most of the modern web, illustrating its importance in enhancing user experience.

💡Web Development

Web Development is the process of creating, designing, and maintaining websites. The script introduces it as the collective work of 'Los Tres Amigos'—HTML, CSS, and JavaScript—which together create what users see and interact with on the web. It is the main theme of the video, emphasizing the collaborative nature of these technologies in building the user interface of websites.

💡Front End Web Development

Front End Web Development focuses on the parts of the website that users directly interact with, which includes the visual design and user interface. The script explains that it is made possible by HTML, CSS, and JavaScript, and contrasts it with Back End Web Development, which is responsible for the server-side logic and application functionality.

💡Web Browser

Highlights

Every webpage on the internet uses HTML, CSS, and JavaScript as foundational coding languages.

Webpages have languages similar to how Belgium has multiple languages.

HTML is referred to as 'The Builder' in web development.

CSS is known as 'The Artist' for its role in styling websites.

The success of the world wide web is attributed to 'los tres amigos': HTML, CSS, and JavaScript.

Transcripts

Every webpage on the internet uses HTML, CSS, and JavaScript.

Think of them as the foundational coding languages of the internet.

Just like how Belgium has 3 languages (French, Dutch, German), webpages also have languages.

In the case of websites, their languages are HTML, CSS, and Javascript.

Sure you may have heard of them, but do you really know how they work?

Web Development is what you see when you go to a website.

I call them "Los Tres Amigos".

HTML is Hypertext Markup Language, or "The Builder".

CSS is Cascading Style Sheets, which I consider "The Artist".

And JavaScript "The Wizard".

They are all different languages, and work differently.

But HTML, CSS, and Javascript need one another to make a website.

Imagine you want to code this homepage using HTML.

But just HTML.

HTML essentially would define all the content, the text, the images, the links.

But without CSS "The Artist", and without JavaScript "The Wizard": an HTML only website

would look like this.

CSS adds the styling to a website.

CSS can't live without HTML or else there would be nothing to style.

It is responsible for outlining the colors, the fonts, and the positioning of content.

Your website will now look like this.

Now we come to Javascript, "The Wizard".

Popup air messages, the autocompletes that you use, that is all JavaScript.

Now that you understand how it works, and the "3 Amigos" here are 3 things to remember

about HTML, CSS, and Javascript.

1 - they make up what is called "Front End Web Development".

Front End Web Development is what you see when you land on a page, as opposed to Back

End Web Development, is actually what makes an application on the web work.

2 - Web browser like Firefox and Chrome, translate these three languages into the visual webpage.

Without a browser these languages are just words on a page.

Sometimes, because of this, website look slightly different on Chrome, Firefox and definitely

look different on Internet Explorer.

Because all of these Browsers translate a little differently.

3 - HTML, CSS, and JavaScript are constantly evolving.

It's just like any language.

These coding languages have a history.

They've been around for a few years now.

Right now the standard language procedures for HTML, CSS, and Javascript are called "HTML5".

There's even a body and a society online that manages the rules and best practices of how

to build for Front End Web Development.

So in the beginning you actually had HTML controlling a lot of visual aspects.

You used a "bold" tag to make text bold.

You used a "center" tag to make your text centered.

But over time, after the 90s, you actually had CSS making up most of that.

In the beginning JavaScript was mostly for popups and now it animates most of our websites.

So whatever you see on the world wide web, you have "los tres amigos" to thank for it.
