HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are fundamental technologies used in web development. HTML is a markup language that defines the structure and content of web pages, utilizing tags to create elements such as headings, paragraphs, lists, links, and images. CSS is a style sheet language that controls the visual presentation of HTML elements, allowing developers to modify properties like color, font, size, and layout.

These two languages work in tandem to form the foundation of every website on the internet. HTML provides the structural framework, while CSS enhances the visual appearance and user experience. Together, they enable the creation of visually appealing and functional websites.

Proficiency in HTML and CSS is essential for web developers and designers. Understanding how to effectively use these languages is crucial for anyone involved in website creation or maintenance. As the web continues to evolve, HTML and CSS remain core technologies that are constantly updated to meet the changing needs of modern web development.

   There are various types of selectors, including element selectors, class selectors, ID selectors, and descendant selectors. Properties are used to define the styles that will be applied to the selected elements. These properties include color, font-size, margin, padding, border, and more.

   Values are used to specify the specific style that will be applied to the selected elements. For example, the color property can have values such as red, blue, #000000, or rgb(255, 0, 0). Layout is an important aspect of CSS that allows you to control the positioning and arrangement of elements on a web page.
