If you want an entire line in between paragraphs, you use the <p></p>. Put the first one at the beginning of the paragraph and the second one at the end, like so:
<p>I am writing a paragraph to show how to use the html paragraph tags.</p>
<p>This is another paragraph to illustrate the point.</p>
And this is how it would turn out:
I am writing a paragraph to show how to use the html paragraph tags.
This is another paragraph to illustrate the point.
You have a full sapce between - much like hitting the return button twice after the end of a paragraph.
If you would like just a line break - like hitting the return button once - add the <br> tag to the end of the sentence (this tag exists by itself, it is not a pair), like so:
The < br > is very helpful for: <br>
lists<br>
things you would like to highlight<br>
poems<br>
And this is how it would turn out:
The < br > tag is very helpful for:
lists
things you would like to highlight
poems
Hope that helps you - and that it makes sense!
