A beginner's HTML course typically covers the fundamentals of HTML (Hypertext Markup Language), including tags, attributes, elements, and basic structure. It might include topics like creating headings, paragraphs, lists, links, images, tables, forms, and basic styling with CSS (Cascading Style Sheets). The course may also touch on accessibility, best practices, and how HTML fits into web development. Interactive exercises and projects are often included to reinforce learning.
