The structural markup of a webpage is essentially just the tags that make up the structure, like the paragraphs and headings. You can use tags h1-h6 to display the header — h1 being the biggest and h6 the smallest. You can also change the appearance of text by using bold or italics tags.
Additionally, there are certain tags that do not change the structure of the website, but rather add extra information for users. For example, the tags “strong” and “emphasis” can be used to indicate where readers should place emphasis on a word or phrase. Further, you can use the blockquote or q tags to present quotes to the reader in an understandable way.
As with any design, the use of color can be very important in your website. You can change the background color of your page, as well as the color of your type. When doing so, it is very important to understand the use of contrast to ensure that viewers of the site can understand your information.
