HTML provides us with six levels of headings represented by <h1> through to <h6>.  Each heading level has corresponding styles such as responsive font-sizes, margins and line heights. Typically, the headings are not constrained by line length unless they are inside the <article> tag where they take on the line length of a paragraph <p> tag.


Consider using headings to:


    

  • provide structure and hierarchy to the blocks of content

  • group subtopics under a larger grouping

  • break up different topics on a single page




    






                
                    





    
    
    


Usage example:


    

  • heading for a recreation facility followed by next level heading for hours of operation, amenities, etc.

    • red line:
      • two line length options (short, long)
      • two alignment options (left, right)

For the subtitle with red underline variation, choose a line length that matches closely with the amount of text in the title.

Do not skip any heading levels i.e. go from heading 2 straight to heading 4. This creates accessibility issues for users using assistive technologies such as screen readers to peruse the content.



    





Do not use heading 1 more than once on a page as this creates confusion for users using assistive technologies such as screen readers to peruse the content.
