css - Double line break HTML tag -

I am creating a website and myself & lt; / Br & gt; & Lt; / Br & gt; Much more to create a new paragraph like this ...

  Paragraph 1 paragraph 2   
 I already have a  & Lt; Tab & gt; Tag on the indented paragraph, but I'm wondering if I've been for a while since   
 Can someone tell me in the right direction?  
 Thank you!

 If  & lt; P & gt; I.e. (?) Is not required, then you  & lt; Br / & gt;  defaut values ​​can change:  
  br {margin: 2.5 mm 0; / * For example FF / Line-height: 5em; / * Chrome for example *}   
 & lt; = Here is 5 AM to make it clear, :)
