Use of colors in HTML

we can use RGB colors in web pages to make the page more colorful.
Syntax of RGB color code is rgb(rr,gg,bb)

As an example to show green color using RGB code we can write as following, rgb(0,255,0)

You can get RGB code of a color by using “Adobe Photoshop” or any image processing software. But in HTML we us corresponding hexadecimal value of a RGB color code.
Example : for red color

RGB value = (255,0,0)
Hex value = #ff0000

But most web browsers support 17 main colors.
They are

Aqua
Black
Blue
Fuchsia
Gray
Green
Lime
Maroon
Navy
Olive
Orange
Purple
Red
Sliver
Teal
White
Yellow

we can use them without hex value.
We can use following HTML code
<HTML>
<HEAD>
<TITLE>Colors</TITLE>
</HEAD>
<BODY>
<H1>This is in red color</H1>
<H2>This is in green</H2>
This is some text
</BODY>
</HTML>

General syntax of a font tag

We can use many font types by using commas.
Example:

Here if first font is not available then browser show the text using second font.

How to change font size
General Syntax : 
Can change according to 2 methods.
1.use of numbers
We can use numbers from 1 to 7
1 for smallest 7 for largest and 3 for normal size
Then 1 and 2 are smallest size,3 is normal size and 4 to 7 are large size.
2.Use of relative values
Use +1 to +6 for increasing values and -1 to -6 for decreasing values

Example,
This is font size 2
This is font size 7 (larger)
This is relative font size +3
