What is HTML & CSS ?

HTML, or HyperText Markup Language, is the standard markup language for creating web pages and web applications. It is used to structure and format the content of a webpage, including text, images, and other multimedia elements. HTML consists of a series of tags, or elements, that are used to define different parts of a webpage, such as headings, paragraphs, and links.

CSS, or Cascading Style Sheets, is a stylesheet language used to describe the look and formatting of a document written in HTML. CSS is used to control the layout, color, font, and other design elements of a webpage, allowing developers to create visually appealing and consistent webpages. CSS is often used in conjunction with HTML to create dynamic and interactive web pages.

Together, HTML and CSS form the building blocks of modern web development. HTML provides the structure and content of a webpage, while CSS is used to control the appearance and layout of the content. Together, these two languages allow developers to create stunning and interactive web pages that can be accessed from any device with a web browser. 


History of HTML & CSS creation :

HTML (HyperText Markup Language) was first developed by Tim Berners-Lee in 1989 while he was working at CERN (European Organization for Nuclear Research). He wanted to create a way for researchers to share information and collaborate on projects, and so he created HTML as a way to structure and format documents for the World Wide Web.

The first version of HTML was very basic and only included a few tags for formatting text, including headings, paragraphs, and lists. Over the years, HTML has evolved and grown in complexity, with the addition of new tags for things like tables, images, and multimedia.

CSS (Cascading Style Sheets) was developed in the mid-1990s as a way to separate the content of a webpage from its design and layout. Prior to CSS, HTML was used for both structure and style, which made it difficult to change the look and feel of a webpage without changing the content itself.

CSS allowed designers to create style sheets that could be applied to multiple pages, making it easier to change the look and feel of a website without touching the content. This also made it easier to create responsive websites that could adapt to different screen sizes and devices.

Today, HTML and CSS are essential tools for web developers and designers, and they continue to evolve and change with the needs of the web.

How HTML & CSS work ? 

HTML, or Hypertext Markup Language, is a coding language used to create the structure and content of a website. It is used to define the various elements on a webpage, such as headings, paragraphs, images, and links.

CSS, or Cascading Style Sheets, is a coding language used to define the style and layout of a webpage. It is used to control the look and feel of a website, including things like font size and color, background color and images, and the position of elements on the page.
When a user opens a webpage, their web browser reads the HTML and CSS code and uses it to display the content and style the page accordingly. The HTML provides the structure and content, while the CSS provides the styling.

HTML and CSS work together to create a cohesive and visually appealing webpage. For example, an HTML tag might be used to create a heading element, and then CSS can be used to control the font size and color of that heading.

HTML and CSS can be written directly in the code of a webpage, or they can be linked to external files that contain the code. This allows for easier maintenance and updates to the code, as changes only need to be made in one place rather than on every individual webpage.

Overall, HTML and CSS work together to create the structure and appearance of a website, allowing web developers to create visually appealing and functional websites for users to enjoy.

What is a HTML 5 & CSS 3 ?

HTML5 and CSS3 are two programming languages that are used to create and style websites. HTML5 stands for HyperText Markup Language and is used to structure the content on a webpage. It consists of various tags and attributes that are used to define the structure and layout of a webpage, such as headings, paragraphs, and links.

CSS3, on the other hand, stands for Cascading Style Sheets and is used to style and design the look and feel of a website. It allows developers to specify how the content on a webpage should be displayed, including font sizes, colors, and layout.

Together, HTML5 and CSS3 are powerful tools for creating modern and responsive websites that can adapt to different screen sizes and devices. HTML5 introduces new features such as video and audio support, as well as improved support for mobile devices and offline access. CSS3 introduces new features such as rounded corners, box shadows, and gradients, which allow developers to create more visually appealing websites.

Overall, HTML5 and CSS3 are essential tools for building and designing websites that are fast, user-friendly, and visually appealing. They are constantly evolving and have become the standard for creating websites that are compatible with modern browsers and devices.
