How can we apply styles in List Dashboard?

You can add custom css to the section where the dashboard is placed with the code similar to the one below:

.dashboard-listed-grid-module .grid-primary-column{
	font-weight: bolder;
}

this will make the primary column for the dashboard to be in bold text:

All you need is to correctly specify paths to elements on the page in css.
