Reduce space between Title and Paragraph in Visual Editor?

Hi there,
Please note that CSS styling is not controlled by the Black Studio TinyMCE Widget.
In your case you should override the following CSS snippet (provided by Page Builder) and reduce margin-bottom and / or padding-bottom.

.panel-grid-cell .widget-title {
    text-align: center;
    margin-bottom: 50px;
    position: relative;
    font-weight: 600;
    line-height: normal;
    text-transform: uppercase;
    padding-bottom: 10px;
}
