Change widget title colors

Use this snippet to change the title color for all widgets that you use in a Page Builder layout.

.panel-grid-cell .widget-title {
       color: #000; //replace #000 with the color you want
}

You can also do it for just specific rows by using this

#pg-204-3 .widget-title {
       color: #000; //replace #000 with the color you want
}

In the code above replace 
204 with your page ID and 3 with the position of your row (note: numbering starts from 0)
