The Css Border property is used to add borders to html elements. With the Css

Border Property width, color and border type can be changed. Border Radius can also be used to produce round corners in supported

Browsers like IE9, Opera 8+, Firefox and webkit browsers like Chrome &

Safari
.



IE9 and Opera both use the same code to display Border Radius. For using Border Radius in Firefox and Webkit Browsers a prefix -moz- for Firefox and -webkit- for Webkit browsers like Chrome and Safari.












If your Browser supports Css Borders then you can see the following border effects.

Advanced Round Rectangle
Advanced Bullet


Advanced Leaf





Borders can be applied in the following ways.





Border Syntax



border-(sub-property): (top) (right) (bottom) (left);












sub-property



top

right

bottom

left




we can use width, color, style and radius as sub-properties of Border.

This value gets assigned to the top portion of the border


This value gets assigned to the right portion of the border

This value gets assigned to the bottom portion of the border

This value gets assigned to the left portion of the border






Here in sub-property we can use width, color, style and radius as sub-types of Border.





Four values need be to defined.

  1. The first value gets assigned to the top portion of the border.
  2. The second value gets assigned to Right portion of the border.
  3. The third value gets assigned to the Bottom portion of the border.
  4. The last value gets assigned to the left portion of the border.
The values in the right are used to assign numerical values in pixels

for width and radius. Colors can be assigned to the borders by using RGB

Color Code, Hex Color Code or by Color names.







Border Color






Syntax : border-color: (top) (right) (bottom) (left);



Example: border-color: #85C226 #F7C200 #4493A0 #DF127B ;












Here the top border is green(#85C226) in color,



right border is yellow(#F7C200),



the bottom has blue(#4493A0)



and Left border is pink(#DF127B) in color.











Border Styles Important

This property must be used if you are using any of the Border properties.



Without using this border-style property you won't see any borders at all.





Syntax : border-style: (top) (right) (bottom) (left);




Example: border-style: solid dotted groove double;











Here the top border (green) has a solid style,



right (yellow) one has dotted,




bottom (blue) one has groove and



the left (pink) one has the double style.








Border Width

Syntax : border-width: (top) (right) (bottom) (left);




Example: border-width: 5px 10px 15px 20px;







Here Top (green) border's width is 5 pixel,



right (yellow) border is 10 pixel wide,




bottom (blue) is 15 pixel



and left (pink) is 20 pixel wide.








Border Radius

Syntax : border-radius: (top-left) (top-right) (bottom-right) (bottom-left);




Example: border-radius: 0px 30px 70px 20px;



For displaying round corners Border Radius property is used.



IE9 and Opera use the same code.

For Firefox a prefix -moz- needs to be added before the code. And for Webkit Browsers -webkit- needs to be added before the code.


Box-shadow property for all the browsers.







For IE and Opera



For Mozilla Firefox

For Webkit Browsers


box-shadow:

-moz-box-shadow:

-webkit-box-shadow:



0px 30px 70px 20px;

0px 30px 70px 20px;

0px 30px 70px 20px;

























No Border radius ( 0px ) has been applied on the top-left (green-pink) corner.



Border radius ( 30px ) has been applied on the top-right (green-yellow) corner.



Border radius ( 70px ) has been applied on the bottom-right (blue-yellow)corner.



Border radius ( 20px ) has been applied on the bottom-left (blue-pink) corner.











Now lets try making Hemisphere, Round Rectangle, Bullet and Leaf as shown at the top.




What we'll do here is create an empty <div> </div> inside your <body> </body> tags, then assign some width and height to it. We'll apply a thick border width to it so that the effect is visible clearly.

<head>

<style type=text/css>


#example{
width:120px; height:60px; border:thick solid; }
</style> </head>











! : Line 8 border:thick solid;



Border width (thick) wont work unless border type (solid) is also included in the code.










Please Note !The width and height as defined above will be same for all the <div> </div> tag's below. Just add the border-properties that I'm going to explain below.

Hemisphere



Use values of width, height and border as defined above. Only add these codes to your existing stylesheet or make a new one.

#hemisphere{
border-radius:100px 100px 0 0 ; -moz-border-radius:100px 100px 0 0 ; -webkit-border-radius:100px 100px 0 0 ;
}

=> Top Border

=> Right Border

=> Bottom Border


=> Left Border















Advanced Hemisphere



Now we'll add more effects to the border by applying different values for width and using different border style.

#adv-hemisphere{
border-width: 4px 30px 4px 30px; border-style: groove ridge dashed groove; border-color: #cc0000; border-radius:100px 100px 0 0 ; -moz-border-radius:100px 100px 0 0 ; -webkit-border-radius:100px 100px 0 0 ;
}








Here Border Properties like border-width, border-style and border-color are added and rest of the codes for Advanced Hemisphere are same as Hemisphere above.







Round Rectangle





Here all the corners have the same border radius (20px).

border-radius (40px) for both top corners and for both the bottom


corners (60px).

}

















Bullet



Same border radius (20px) is assigned to the corners on the left, and

same border radius (100px) is assigned to the right corners.

}

}

and bottom-right corners.
