HTML <section> tag
When writing in HTML, the <section> tag is a block element used to group thematically similar content together. Good examples are generic documents and application sections. As a general rule, <section> shouldn't be used if there is no natural <heading> for it. The following sections contain information about this tag, including an example of it in use, as well as related attributes and browser compatibility.
This element is unique in that it is a phrase tag, which indicates that a section of text has structural meaning.
The <section> tags should not be used for styling, instead use the <div> tags for styling changes. If the content that would be contained in the <section> tag relates to other portions of the page with its own heading then consider using the <section> tags.
Example of <section> code
Within an HTML tag, an attribute dictates certain aspects of an HTML element. Attributes are made up of a name and value pair. While the <section> tag does not have any unique attributes, it does utilize all of the standard attributes.
