Add Shadow to the Text
It is possible to add a shadowing to your text with the configuration option “Shadow (optional)”. You need to pass a quadruple separated by empty spaces such as 5pt 6pt 7pt #808080, where entries correspond to horizontal offset, vertical offset, blur radius, and shadow color, respectively.
Passing the value 5pt 6pt 7pt #808080 sets the vertical offset to 5pt horizontal offset to 6pt, blur radius to 7pt, and shadow color to #808080.
