Where is the style for WordPress image class wp-image-####?

It seems whenever I insert an image to a WordPress post, it will add the following tag:

<img class="aligncenter wp-image-41880" src="https://www.datanumen.com/blogs/wp-content/uploads/2024/03/photoshop-certification-introduction.jpg" alt="Photoshop Certification Introduction " width="600" height="343" />

But in Chrome DevTools, I try to search for the style of wp-image-41880 but cannot find any. So what is the usage of this class wp-image-41880? Also what is the meaning of the digits 41880?

    These numbers are the references created to process the image using javascript.

    var elements = document. getElementsByClassName('wp-image-41880')

    If I understand your question correctly, you are asking why wp-image-41880 is added as a class to your img tag.
    It’s a feature of wordpress. the 41880 is the attachment ID of the image in the database.
    This class is generated by WordPress to identify and style each image in a post.

    By default there is no style defined by that class name, but you may want to chagne style of one of images in your post.

    let’s say you have 2 different image in a page, each one has its own class, e.g. wp-image-41880 and wp-image-41881, you can easily change style of each image by their auto generated class name.

    you may find other class names that generate by wordpress, e.g. in body (it depends on your theme) tag of a single blog post there are classes like single and postid-1111 (1111 is just an example, it’s related to post id in your DB).
