SOLUTION

• HTML defines six levels of headings.
• The heading levels are h1, h2, h3, h4, h5, h6.
• Level 1 is the highest or main level of heading.
• Level 2 is a subheading of Level 1.
• Level 3 is a subheading of Level 2, and so on through Levels 4 and 5.
• The number of headings to use in a paper depends on the length and complexity of the work.
• If only one level of heading is needed, use Level 1.
