Border CSS

Border Style
The border-style property specifies what kind of border to display.
The following values are allowed:
  • dotted - Defines a dotted border
  • dashed - Defines a dashed border
  • solid - Defines a solid border
  • double - Defines a double border
  • groove - Defines a 3D grooved border. The effect depends on the border-color value
  • ridge - Defines a 3D ridged border. The effect depends on the border-color value
  • inset - Defines a 3D inset border. The effect depends on the border-color value
  • outset - Defines a 3D outset border. The effect depends on the border-color value
  • none - Defines no border
  • hidden - Defines a hidden border
The border-style property can have from one to four values (for the top border, right border, bottom border, and the left border).
Example:

p.dotted {border-style: dotted;}
p.dashed 
{border-style: dashed;}
p.solid 
{border-style: solid;}
p.double 
{border-style: double;}
p.groove 
{border-style: groove;}
p.ridge 
{border-style: ridge;}
p.inset 
{border-style: inset;}
p.outset 
{border-style: outset;}
p.none 
{border-style: none;}
p.hidden 
{border-style: hidden;}
p.mix 
{border-style: dotted dashed solid double;}

Border Width:

The border-width property specifies the width of the four borders.
The width can be set as a specific size (in px, pt, cm, em, etc) or by using one of the three pre-defined values: thin, medium, or thick.
The border-width property can have from one to four values (for the top border, right border, bottom border, and the left border).
<!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;
}

p.seven {
    border-style: solid;
    border-width: 2px 10px 4px 20px;
}
</style>
</head>
<body>

<h2>The 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>
<p class="seven">Some text.</p>

<p><b>Note:</b> The "border-width" property does not work if it is used alone.
Always specify the "border-style" property to set the borders first.</p>

</body>
</html>

 

Border Color
The border-color property is used to set the color of the four borders.
The color can be set by:
  • name - specify a color name, like "red"
  • Hex - specify a hex value, like "#ff0000"
  • RGB - specify a RGB value, like "rgb(255,0,0)"
  • transparent
The border-color property can have from one to four values (for the top border, right border, bottom border, and the left border). 
If border-color is not set, it inherits the color of the element.
<!DOCTYPE html>
<html>
<head>
<style>
p.one {
    border-style: solid;
    border-color: red;
}

p.two {
    border-style: solid;
    border-color: green;
}

p.three {
    border-style: solid;
    border-color: red green blue yellow;
}
</style>
</head>
<body>

<h2>The border-color Property</h2>
<p>This property specifies the color of the four borders:</p>

<p class="one">A solid red border</p>
<p class="two">A solid green border</p>
<p class="three">A solid multicolor border</p>
<p><b>Note:</b> The "border-color" property does not work if it is used alone. Use the "border-style" property to set the borders first.</p>

</body>
</html>

Border - Individual Sides

From the examples above you have seen that it is possible to specify a different border for each side.
In CSS, there is also properties for specifying each of the borders (top, right, bottom, and left):
<!DOCTYPE html>
<html>
<head>
<style>
p {
    border-top-style: dotted;
    border-right-style: solid;
    border-bottom-style: dotted;
    border-left-style: solid;
}
</style>
</head>
<body>

<p>2 different border styles.</p>

</body>
</html>


Note:
If the border-style property has four values:
  • border-style: dotted solid double dashed;
    • top border is dotted
    • right border is solid
    • bottom border is double
    • left border is dashed
If the border-style property has three values:
  • border-style: dotted solid double;
    • top border is dotted
    • right and left borders are solid
    • bottom border is double
If the border-style property has two values:
  • border-style: dotted solid;
    • top and bottom borders are dotted
    • right and left borders are solid
If the border-style property has one value:
  • border-style: dotted;
    • all four borders are dotted
The border-style property is used in the example above. However, it also works with border-width and border-color.


<!DOCTYPE html>
<html>
<head>
<style>
p {
    border-style: dotted solid;
}
</style>
</head>
<body>

<p>2 different border styles.</p>

</body>
</html>

Border - Shorthand Property
As you can see from the examples above, there are many properties to consider when dealing with borders.
To shorten the code, it is also possible to specify all the individual border properties in one property.
The border property is a shorthand property for the following individual border properties:
  • border-width
  • border-style (required)
  • border-color
<!DOCTYPE html>
<html>
<head>
<style>
p {
    border: 5px solid red;
}
</style>
</head>
<body>

<h2>The border Property</h2>

<p>This property is a shorthand property for border-width, border-style, and border-color.</p>

</body>
</html>





Rounded Borders:


<!DOCTYPE html>
<html>
<head>
<style>
p.normal {
    border: 2px solid red;
}

p.round1 {
    border: 2px solid red;
    border-radius: 5px;
}

p.round2 {
    border: 2px solid red;
    border-radius: 8px;
}

p.round3 {
    border: 2px solid red;
    border-radius: 12px;
}
</style>
</head>
<body>

<h2>The border-radius Property</h2>
<p>This property is used to add rounded borders to an element:</p>

<p class="normal">Normal border</p>
<p class="round1">Round border</p>
<p class="round2">Rounder border</p>
<p class="round3">Roundest border</p>

<p><b>Note:</b> The "border-radius" property is not supported in IE8 and earlier versions.</p>

</body>
</html>
