Common color Codes

Red: #ff0000或 #f00

Different notation and units of values

In addition to the English word red, we can also use the hexadecimal color value #ff0000:

#ff0000; }

To save bytes, we can use the abbreviated form of CSS:

#f00; }

We can also use RGB values in two ways:

#ff0000rgb(100%,0%,0%); }

Note that when RGB percentages are used, the percent sign is written even if the value is 0 o'clock. But in other cases it is not necessary to do so. For example, when the size is 0 pixels, px units are not required after 0, because 0 is 0, regardless of the unit.
