A color control attribute (on the serial 15)
(4) hex
In the front-end development to represent the color, in fact, is the essence of RGB, HEX is represented by two each by a hexadecimal color.
For example: # FFEE00, where FF represents G R, EE represented, is represented by B 00
Note: The hexadecimal and decimal conversion publicity, your own Baidu
(5) in CSS hexadecimal color as long as the two are the same for each, it can be abbreviated to one.
For example: # FFEE00 can be written as # FE0
NOTE: If the current two digits corresponding to the colors are not the same, so can not be short; if the two numbers are not the same belong to the same color, not abbreviated
<head> <meta charset="UTF-8"> <title>d66_attribute_of_color2</title> <style> p{ color: #ff4b54; } </style> </head> <body> < The p- > We are using a hex </ the p- > </body>
We use this property when it is impossible to remember every color, so webstorm we provide the color picker to select.
