CSS Color Keywords


This page will explain the transparent, currentcolor,
and
inherit keywords.

The transparent Keyword
The transparent keyword is used to make a
color transparent. This is often used to make a transparent background color for
an element.

Example
Here, the background color of the <div> element will be fully
transparent, and the background image will show through:

body {  background-image: url("paper.gif");}div {  
background-color: transparent;}

Note: The transparent
keyword is equivalent to rgba(0,0,0,0). RGBA color values are an extension of
RGB color values with an alpha channel - which specifies the opacity for a
color. Read more in our CSS RGB chapter and in
our CSS Colors chapter.


The currentcolor Keyword
The currentcolor keyword is like a variable
that holds the current value of the color property of an element.
This keyword can be useful if you want a specific color to be consistent in an
element or a page.

Example
In this example the border color of the <div> element will be blue, because the
text color of the <div> element is blue:

div {  color: blue;  border: 10px solid currentcolor;}

Example
In this example the <div>'s background color is set to the current color
value of the body element:

body {  color: purple;}div {  background-color:
currentcolor;}

Example
In this example the <div>'s border color and shadow color is set to
the current color value of the body element:

body { color: green;}div {   box-shadow: 0px 0px
15px currentcolor;  border: 5px solid currentcolor;}

The inherit Keyword
The inherit keyword specifies that a
property should inherit its value from its parent element.
The inherit keyword can be used for any CSS
property, and on any HTML element.

Example
In this example the <span>'s border settings will be inherited from
the parent element: 

div {  border: 2px solid red;}span {  border:
inherit;}
