HTML

HTML is a markup language used to create static web pages and web applications. CSS is a style sheet language responsible for the presentation of documents written in a markup language

  1. Structure: HTML documents consist of nested elements that define the structure of the content. Elements are enclosed in tags, which are typically represented by angle brackets (<>). Tags usually come in pairs: an opening tag and a closing tag, with the content nested between them.
  2. Elements: Elements are the building blocks of HTML documents. They can be structural or semantic. Each element serves a specific purpose in defining the structure or meaning of the content.
  3. Attributes: Attributes provide additional information about HTML elements. They are specified within the opening tag of an element and consist of a name and a value. Attributes modify the behavior or appearance of an element. For example, the src attribute in the tag specifies the source of an image.
  4. Document Type Declaration (DOCTYPE): The DOCTYPE declaration is an instruction to the web browser about what version of HTML the page is written in. It helps the browser render the page correctly.
  5. Semantic HTML: Semantic HTML refers to using HTML elements according to their meaning or purpose rather than just for styling. Semantic HTML makes the structure of the web page more understandable for both humans and machines, such as search engines or screen readers.
  6. HTML5: HTML5 is the latest version of HTML, introducing new elements, attributes, and APIs for modern web development. It provides better support for multimedia, graphics, and interactive content without the need for third-party plugins like Flash.
  7. Cascading Style Sheets (CSS): While HTML defines the structure of a web page, CSS is used to style and layout the content. CSS allows developers to control the visual presentation of HTML elements, such as colors, fonts, margins, and positioning.
  8. JavaScript: JavaScript is a programming language commonly used alongside HTML and CSS to add interactivity and dynamic behavior to web pages. It can be used to handle user interactions, manipulate the DOM (Document Object Model), and communicate with servers to fetch or send data asynchronously.
  9. HTML is the backbone of web development, serving as the foundation upon which web pages are built. It is essential for anyone involved in creating content for the web to have a solid understanding of HTML./li>

  1. Style Rules: CSS works by associating style rules with HTML elements. These rules define how the content of those elements should be displayed. A style rule consists of a selector and a declaration block. The selector specifies which HTML elements the rule applies to, and the declaration block contains one or more declarations separated by semicolons. Each declaration consists of a property and a value, defining the style to be applied.

  2. Selectors: CSS selectors are patterns used to select the elements you want to style. There are various types of selectors, including element selectors, class selectors, ID selectors, attribute selectors, and more. Selectors can also be combined to target specific elements more precisely.
