Switch form paragraph mode to line break mode in WYSIWYG editor because of client request?

Question

I'm building a website fro a client which uses TinyMCE as the main WYSIWYG editor. Now my client asked if it is possible to write a line and make a line break and then continue without leaving a space between the text before and after the line break (e.g. just like in word).

I told him that the web uses paragraph for formatting and not line breaks. Still he'd like to use line breaks for formatting. Should I convince him not to use line breaks for formatting or should I just switch TinyMCE to line break mode (which the is not recommended in the TinyMCE documentation).

Answer 1

Simply use the <br /> tag wherever you want a new line...

If tinyMCE doesn't have a button for that already, I remember it was dead simple to write plugins like that with a few lines of javascript.

Same as on SE, you can use it like this:

This should work <br />with no problems.

This should work
with no problems.

Answer 2

Why not just set the CSS for <p> tags for the areas of the site you are concerned with so that they have no margin or padding?

.mycontent p{
    margin:0;
    padding:0;
}
