This book teaches you to create websites using the HTML, CSS, and JavaScript coding languages.
All websites are created in three basic technologies: HTML, CSS and JavaScript. They are the building blocks of the modern web development. If you want to start developing web sites or you just want to know how web sites work, then these are the three languages to learn.
## What is HTML?
HTML stands for HyperText Markup Language, and is the foundation of all Web pages. Structures and organizes content (headings, paragraphs, images, links, tables, forms). Remember HTML is the structure of a house—it provides the framework of where things will be placed, but doesn't actually say what things will look like.
For instance, HTML can make the browser know that a block of text is a heading, that an image should be placed in a specific position, or that a button should be shown. HTML is the backbone of a website because if there was no HTML, there would be no structure or any meaning to the website.
## What is CSS?
The appearance of a website is achieved by means of CSS (Cascading Style Sheets). It manages colors, fonts, layout, spacing, animation and responsive design. HTML is like the bones and bones are the clothes, furniture and decorations that give the house a nice look.
With CSS, developers can build beautiful-looking sites that will display well on desktop, tablet, and mobile devices. With the advent of modern CSS features like Flexbox and Grid, creating responsive layouts that will adapt to varying screen sizes is simpler than ever.
CSS also enhances the user experience by incorporating hover effects, transitions, shadows, gradients, and animations, creating a sense of smoothness and professionalism in the website's appearance.
## What is JavaScript?
JavaScript is the language used to make websites come alive. HTML gives the structure, CSS gives the design and JavaScript gives the functionality and interactivity.
The developers can build an image slider, a form that is interactive, pop up messages, calculators, interactive menus, search filters, live chat widgets and many more useful things using JavaScript. It enables web pages to react immediately to user actions without having to continually download the page.
Today, JavaScript is one of the most popular programming languages in the world. It can be used for web development as well as for web apps, mobile apps, games, and also for server-side development, such as Node.js.
HTML, CSS, and JavaScript are used together to develop web pages.HTML, CSS and JavaScript are combined to create web pages.
The three technologies have come together to build contemporary websites.
The structure and content are created in HTML.
* **CSS** styles the content and enhances the visualisation of it.
JavaScript provides dynamic features and user interaction.
Suppose you were to construct a car. HTML helps to form the frame, CSS colors and designs the frame, and JavaScript provides the engine that powers the frame!
Why are these technologies being learned?
The first step to becoming a front-end or full stack web developer is learning HTML, CSS, and JavaScript. They are easy to learn and popular, and work in all modern web browsers.
These skills bring opportunities in web development, freelance projects, digital marketing, implementing UI/UX, and software engineering. Anyone who has a good command of front-end skills is in demand as it is essential for businesses of all sizes to have websites.
Conclusion
The web is built from basic components such as HTML, CSS and JavaScript. HTML is the back-bone, CSS is the beauty, and JavaScript gives it life. They work in conjunction with one another to help developers create fast and responsive websites with great user experience. From building a basic portfolio to developing a large web-based application, these are the three technologies you need to grasp to be successful in web development.
