The main difference between div id and div class is that the div id involves assigning an id attribute to a specific div element to apply styling or interactivity to that element, while div class involves assigning the class attribute to several div elements to apply styling or interactivity to a set of div elements.
HTML stands for HyperText Markup Language. It is the basic language for all other web technologies. Generally, the main objective of using HTML for web development is to build the structure of the webpages. Programmer can define paragraphs, tables, images, lists, headings and many other elements using HTML. Furthermore, block-level elements in HTML start on a new line and take up the whole available width. For example, div is a block-level element. Programmer can use attributes to describe the characteristic of HTML elements. Two such attributes are id and class. Therefore, it is possible to use these two attributes with div as well.

Difference Between div id and div class
Definition
div id is the assignment of the id attribute to a div block to apply styling or interactivity to that specific div block. In contrast, div class is the assignment of a class attribute to a number of div blocks to apply styling or interactivity to a group of div blocks. Thus, this is the main difference between div id and div class.
Number of elements
Furthermore, the div id is used for a specific div block. On the other hand, the div class is used for a set of div blocks. Hence, this is another difference between div id and div class.
Conclusion
In brief, div is a block-level element. The programmer can use attributes to explain the characteristics of an HTML element such as div. Moreover, two common attributes are id and class. The main difference between div id and div class is that div id involves assigning an id attribute to a specific div element to apply styling or interactivity to that element while div class involves assigning the class attribute to several div elements to apply styling or interactivity to a set of div elements.
