Additionally, B does not hold an instance of A, so:

This might make it clearer

Say you have two classes, A and B. Is it possible to instantiate both classes once and then let class B call methods in class A, and vice versa?
It can be done using double colon (::) ... ... but then the method becomes static - is that a disadvantage...

The CSS class is the modern method....
The <b> tag is from older versions of HTML as such .
That approach allows me to separate the CSS class rather than the actual html markup.
