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.
Note: This element is unique in that it is a phrase tag, which indicates that a section of text has structural meaning.
Tip: The <section> tags should not be used for styling, instead use the <div> tags for styling changes. If the content that would be contained within the <section> tag relates to other portions of the page with its own heading then consider using the <section> tags.
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.
