The outline-width property is used to set the width of the outline. Its value should be a length or one of the values thin, medium, or thick, just like the border-width attribute.
Example
<html> <head> </head> <body> <p style = "outline-width:thin; outline-style:solid;"> This text is having thin outline. </p> <br /> <p style = "outline-width:thick; outline-style:dashed;"> This text is having thick outline. </p> <br /> <p style = "outline-width:5px; outline-style:dotted;"> This text is having 5x outline. </p> </body> </html>
