Semantic markup is using HTML tags to mark up elements in a meaningful and descriptive way. Following principles of semantic markup is important. When semantic markup is used to create a Web page, the structure is clear even without applying a style sheet. Although people who visit your site don't see the code, the devices they use do. Browsers, search engines, and assistive devices for people with disabilities all use HTML code to help interpret your Web page.
The concept of meaningful markup is probably easiest to understand by considering an example of non-semantic markup, or markup that is used solely for presentation rather than for structure or meaning. An example would be the first line of text on a Web page, which usually serves as a heading. A nonsemantic approach to marking up the text would be to create a style to display it as bold and red, without also applying an
tag to mark the text as a first-level heading. Using this method, the text may look like a heading, but it has no structural meaning without the HTML tag and devices will not recognize it as a heading.
