• Tags in HTML are special keywords enclosed within angle brackets (< >).
• They define elements and instructions in an HTML document.
• Tags structure and format content on a webpage.
• Examples of tags include headings, paragraphs, links, images, and lists.
• Tags can have attributes to provide additional information or modify their behaviour.
• Opening and closing tags mark the beginning and end of an element, with content placed in between.
• Some tags are self-closing, like the <br> tag for line breaks.
• Tags can be nested to create complex structures.
• HTML tags are case-insensitive, but lowercase is commonly used for better readability.
