Anyone past the stage of beginner with web page design for the 21st century knows that HTML defines the content and CSS defines the appearance. As such asking an appearance question about HTML is meaningless since that isn't what HTML is for and, apart from the beginner just starting out, 21st Century web designers know that.
As such my comment implied that in asking the question you are presumably a beginner where it comes to 21st century web design. This could mean that are just starting out or it could mean that have been using 20th century web design methods without realising that they are now obsolete. I made no assumptions as to which of these applied to you. The alternative that you actually do know 21st century web design and deliberately asked what you knew to be a meaningless question is the alternative that I did not believe applied.
In any case arguing over what you have interpreted my comments to mean does not get you any further in finding out how to do what you were asking about in the first place which was about how to insert vertical whitespace into your content - which is done by applying the appropriate padding and margins to block level content and by applying an appropriate line-height to inline content.
