css hat 3 neue Farbmodi hinzugefügt: 1. RGBA-Modus, der dem RGB-Modus Alpha-Transparenz hinzufügt, z. B. „rgba(255,0,0,0.5)“; 2. HSL-Modus, z. B. „hsl( 360 ,50%,50%)"; 3. HSLA-Modus, der dem HSL-Modus Alpha-Transparenz hinzufügt.
Die Betriebsumgebung dieses Tutorials: Windows 7-System, CSS3-Version, Dell G3-Computer.
1. CSS1- und 2-Farbdarstellungsmethode (W3C-Standard)
1. Farbnamenmethode (Verwenden Sie Farbschlüsselwörter, um die entsprechende Farbe darzustellen.)
Zum Beispiel: rot (rot), blau ( blau), rosa (rosa)
Vorteile: Bequem und schnell und genauer für bestimmte Farben
Nachteile:
Gibt eine begrenzte Anzahl von Farben an.
Unterstützt keine transparenten Farben
2. HEX-Modus Hexadezimalmodus (Hexadezimal zur Darstellung von Farben verwenden)
Syntax:
#RRGGBB 或 #RGB
Wert:
RR: Roter Wert. Hexadezimale positive Ganzzahl
GG: Grüner Wert. Hexadezimale positive Ganzzahl
BB: Blauer Wert. Hexadezimale positive Ganzzahl
Wertebereich: 00-FF
Zum Beispiel: #FF0000
rot #FFFF00
gelb. #FF0000
红色 #FFFF00
黄色。
优点:表示颜色种类多,使用较方便
缺点:
16进制单位换算很成问题
不支持透明颜色。
特定颜色需要工具配合或者一定的颜色调配知识
3、RGB方式 三原色配色方式
语法:
RGB(R,G,B)
取值:
R: 红色值。正整数 | 百分数
G: 绿色值。正整数 | 百分数
B: 蓝色值。正整数 | 百分数
取值范围:0~255或者0%~100%
例如:rgb(255,0,0)
红色 rgb(255,255,0)
黄色
优点:表示颜色种类多,使用较方便
缺点:
不支持透明颜色
特定颜色需要工具配合或者一定的颜色调配知识
二、CSS3 新增颜色表示方式
1、RGBA模式
此色彩模式与RGB相同,只是在RGB模式上新增了Alpha透明度。
语法:
RGBA(R,G,B,A)
取值:
R: 红色值。正整数 | 百分数
G: 绿色值。正整数 | 百分数
B: 蓝色值。正整数 | 百分数
A: Alpha透明度。取值0~1之间。
例如:rgba(255,0,0,0.5)
半透明红色

2、HSL模式(色轮模式没有透明度)
语法:
HSL(H,S,L)
取值:
H: Hue(色调)。–0(或360)表示红色,120表示绿色,240表示蓝色,也可取其他数值来指定颜色。取值为:0 - 360
S: Saturation(饱和度)。取值为:0.0% - 100.0%
L: Lightness(亮度)。取值为:0.0% - 100.0%
例如:hsl(360,50%,50%)
红色
46d5fe1c7617e3914f214aaf043f4ccf body{background:rgba(0,0,255,0.5);} div{width:300px; height:300px; background:hsl(140,50%,50%); position:absolute; top:0; left:0; } 531ac245ce3e4fe3d50054a55f265927 6c04bd5ca3fcae76e30b72ad730ca86d dc6dce4a544fdca2df29d5ac0ea9906b16b28748ea4df4d9c2150843fecfba68 36cc49f0c466276486e50c850b7e4956
3、HSLA模式(色轮模式有透明度)
语法:
HSLA(H,S,L,A)
取值:
H: Hue(色调)。–0(或360)表示红色,120表示绿色,240表示蓝色,也可取其他数值来指定颜色。取值为:0 - 360
S: Saturation(饱和度)。取值为:0.0% - 100.0%
L: Lightness(亮度)。取值为:0.0% - 100.0%
A: Alpha透明度。取值0~1之间。
例如:hsl(360,50%,50%,0.5
Transparente Farben werden nicht unterstützt. Bestimmte Farben erfordern Werkzeugkoordination oder bestimmte Farbmischungskenntnisse. Positive ganze Zahl |. Prozent
G: Grüner Wert. Positive ganze Zahl |. Prozent B: Blauer Wert. Positive ganze Zahl | Prozent GelbVorteile: Es repräsentiert eine große Farbvielfalt und ist bequemer zu verwenden
