Deep dive into HTML5 global properties: Five key points you need to know

HTML5 is a standard for building and rendering web pages that brings many New functions and features, one of which is global properties. Global attributes are attributes that can be applied to any HTML element. They are universal and affect the entire page. In this article, we’ll take a deeper look at HTML5 global properties and cover five key points you need to know.
