How to hide div class?

Question

css

<div class="dashboard-widget products">

how to hide exactly products inside dashboard-widget ?

preferably via display: none;

Answer 1

It's unclear.
So what?

.dashboard-widget.products {
 display: none;
}

In your screenshot, there is no .products class inside the .dashboard-widget class.
I assume that it is the dashboard-widget with the .products class that needs to be hidden
