Here, I demonstrate some of the basic block tags used to format text in HTML. These include headers (of which there are 6 types in decreasing size), paragraphs, and lists (ordered and unordered).
Below, you can see demonstrations of ordered lists, unordered lists, and nested lists, including those with alternative 'bullet' types.
In summary, the usage of block text can ease readability on websites, as well as provide crucial semantic information to both search engines as well as screen readers.
