HTML (Hypertext Markup Language) is the foundation of web design. Every website you visit is built using HTML. It is a markup language that is used to structure and display content on the web. HTML is a simple language that consists of elements and tags. An element consists of a starting tag, content, and an ending tag. For example, <p> is a starting tag, which is used to indicate a paragraph. The content is the text that goes between the starting and ending tags, and </p> is the ending tag that marks the end of the paragraph.
HTML is responsible for the layout and structure of a web page. It defines headings, paragraphs, links, images, and other elements that make up a web page. One of the best things about HTML is that it is easy to learn and use. It is a fundamental building block of web design, and knowledge of HTML is necessary to create any website.
CSS (Cascading Style Sheets) is used to style HTML documents. It is responsible for the visual appearance of a web page. CSS defines the font size, color, spacing, and layout of a web page. With CSS, you can separate the content and presentation of a web page. This means that you can change the presentation of a page without affecting its content.
CSS is a powerful tool that can significantly improve the appearance of a website. It allows you to control the positioning of elements on a page, as well as the overall look and feel of the website. CSS is a massive topic, and there are many techniques, tools, and best practices to learn.
