If there are smaller texts and side comments that have to be placed in the HTML document, the HTML5 <small> tag is used by the author.

Technically, the use of the HTML5 <small> tag is the same as how it is used for HTML4.01. The only added function is the fact that it works for side comments too in HTML5. Still, the end product is that the size of the texts will appear smaller within the document.

Using this has no complications because it is properly recognized in web browsers like Google Chrome, Internet Explorer, Safari, Opera and Firefox. The HTML5 <small> tag has the capability to provide support for the Event Attributes and Global Attributes in HTML5.
