Hi,

I would like to edit in k2 the lines I am typing in a way I can see in k2 what I am doing.

I mean, when I type a sales page in k2, then

on the website the lines are broken cause the width is smaller on the frontend then in k2.

Hi. This has nothing to do with K2. This is how browsers are rendering HTML. If content doen't fit in a container it will break into next line.
