Hi sanjay.joshi,

 

Please make sure your content is not in the same paragraph, because Heading 1 Heading 2 ... will work on entire paragraph.

 

For example:

 

Example A

 

line one

line two

 

Heading 1 will works on two lines

 

Example B

 

<div>line one</div>

 

Heading 1 will works on first line

 

Regards,

 

Ken
