Best practice for calling classes in CSS

Question

If you have an HTML page with a class in an element, for example <div class="myClass">, it would be best to link to it in CSS like .myClassor div.myClass?

Answer 1

div.myClassmakes style declarations more specific. In other words, it has a higher priority. Therefore, it is sometimes useful to specify it in order to avoid CSS conflicts when you have many developers on board a project and people add classes like no tomorrow. In other words, if you added Bob:

.myClass {
  color: red;
}

and Sarah adds:

div.myClass {
  color: blue;
}

The Sarah class will surpass the Bob class if you have:

<div class="myClass">Sarah FTW</div>
