What is HTML / HTML5?

HTML stands for HyperText Markup Language. It's a markup language used to create and structure web pages. Thanks to HTML, text, images, links, videos and other content can be organized so that they are correctly displayed in a browser.

HTML5 is the fifth major version of HTML. It brings many improvements and new features over previous versions, including native multimedia elements, improved APIs, and enhanced support for modern web applications.

HTML and HTML5 are not programming languages, but description languages, essential to building the infrastructure of websites.

Why use HTML / HTML5 and what's in it for you?

HTML creates the fundamental structure of any web page, which is essential for displaying content on the Internet.

HTML5 brings great value by integrating native multimedia features such as video and audio without the need for external plugins. This simplifies development and improves cross-browser compatibility.

Using HTML5 guarantees a better user experience, enhanced accessibility and the possibility of developing richer, more interactive web applications.

How does HTML / HTML5 work in practice?

HTML organizes content using tags that indicate the structure and nature of the elements displayed. For example, tags for headings, paragraphs, images, links, or sections.

The browser reads the HTML code and interprets these tags to correctly display the web page to the user.

HTML5 introduces semantic tags such as <header>, <article>, <section>, and multimedia elements such as <video> and <audio> that improve code readability and accessibility.

What are the advantages and disadvantages of HTML / HTML5?

The main advantage of HTML is its simplicity and universality: all web browsers support this language.

HTML5 enhances these advantages by providing modern features that facilitate development without recourse to third-party technologies.

However, HTML is limited at the logical and functional level, as it doesn't allow complex calculations or manipulations like a programming language.

Finally, perfect compatibility between all browsers for certain HTML5 functionalities may vary, sometimes requiring specific adaptations.

Concrete examples and use cases for HTML / HTML5

Developers use HTML5 to create rich, responsive websites, integrating videos directly via the <video> tag without an external plugin.

HTML5 forms enable client-side validation with advanced field types like "email" or "date" making data entry and verification easier.

HTML5 is also the basis for Progressive Web Apps (PWAs), which offer an experience close to native applications thanks to specific APIs.
