Hi there,
you can add this PHP snippet to your site:
add_filter( 'generate_start_widget_title', 'widget_title_start_tag' );
function widget_title_start_tag()
{
return '<p class="widget-title custom">';
}
add_filter( 'generate_end_widget_title', 'widget_title_end_tag' );
function widget_title_end_tag()
{
return '</p">';
}

Then you can style it with this CSS:
.widget-title.custom {
font-weight: bold;
font-size: 24px;
}
