The border-width property specifies the width of the four borders.
Demonstration of the different border styles:
<!DOCTYPE html> <html> <head> <style> p.one { border-style: solid; border-width: 5px; } p.two { border-style: solid ; border-width: medium ; } p.three { border-style: dotted; border-width: 2px; } p.four { border-style: dotted ; border-width: thick ; } p.five { border-style: double ; border-width: 15px; } p.six { border-style: double ; border-width: thick; } </style> </head> <body> <h2>border-width Property</h2> <p>This property specifies the width of the four borders: </p> <p class="one">Some text.</p> <p class="two"> Some text.</p> <p class="three">Some text.</p> <p class="four">Some text.</p> <p class="five">Some text.</p> <p class="six">Some text.</p> </body> </html>

<!DOCTYPE html> <html> <head> <style> p.one { border-style: solid; border-width: 5px 20px; } p.two { border-style: solid; border-width: 20px 5px; } p.three { border-style: solid; border-width: 25px 10px 4px 35px; } </style> </head> <body> <h2> The border-width Property </h2> <p> The border-width property can have from one to four values (for the top border, right border, bottom border, and the left border): </p> <p class="one">Some text.</p> <p class="two">Some text.</p> <p class="three">Some text.</p> </body> </html>
