2.7 COLOR CODING
Coding of colour can be done as a combination of Red(RR), Green (GG) and Blue (BB) colour. These coding are
represented in ordered sequence of RR, GG and BB. For example: If we select a colour as Red, then its red value is full,
green value is 00 (i.e. Nil) and blue is also 00 (Nil).
Red=FF(Full)
Green=00 (Nil) <BODY BGCOLOR =“#FF0000 ”>
Blue=00 (Nil)
RR (Red) = FF (Full)
The resulting colour is red, so the red colour has the string
(value) “#Ff0000”. GG (Green) = 00 (Empty)
Similarly, if we select a color blue, then we will assign BB (Blue) = 00 (Empty)
colour value as:
Red = 00 (Nil)
Green=00 (Nil)
Blue = FF (Full)
The table given below shows codes of different colours and their corresponding hexadecimal RGB values:
COLOUR Name HEX RGB Value COLOUR Name HEX RGB Value
Aqua # 00FFFF Black # 000000
Blue # 0000FF Grey # 808080
Green # 008000 Lime # 00FF00
Maroon # 800000 Purple # 800080
Red # FF0000 Silver # C0C0C0
White # FFFFFF Yellow # FFFF00
2.8 THE <DIV> TAG
In an HTML document, a division or section is defined by the <div> tag. The <div> tag is a block-level element used to
group other elements to apply styles or layout properties to them collectively. Block-level elements take up the full
width available and start on a new line. We can use the CSS properties to apply styles. For example:
<html>
<body>
<h1>Welcome</h1>
<div style="border: 5px outset blue; background-color: pink; text-align: center;">
<h2> Hello! I am Sammy. I study in class 12. </h2>
<p> I love to eat pizza and burgers! </p>
</div>
I like to get up early in the morning and go for a walk.
</body>
</html>
