## header 2
### header 3
#### header 4

Output:

header 2

header 3

header 4

Use any of three to draw a horizontal line.

b. Text background

<span style='background:yellow'> message/text  </span>
<span style='background :yellow' > Background color is yellow </span>

c. Text font-family

<span style='font-family:font_family name'> message  </span>
<span style='font-family:Georgia'> It is Georgia font.
<span style='font-family:Helvetica'> It is  Helvetica font.
