There are many different HTML tags used to mark up content. Here are a list of common tags used in sites today.

• H1, H2, H3, H4, H5, H6
  • These tags are different levels of headings used to define hierarchical structure, where 1 is the most important and 6 is least important. 
• P (Paragraph)
  • The paragraph tag is used to annotate a paragraph of content into readable sections. Vertical spacing is automatically added by the browser to achieve this.
