I enjoy writing, and compiling my thoughts, but I'm also a designer (and web designer) so I want it to look good. I stay away from WYSIWYG text editors, because they are often not compatible with one another.
What I really want is to ensure that what I write is done in the most future proof format, but stylish. I've been using HTML for mark-up and css for style, because of my familiarity with it, but I'd like to hear your recommendations.
What do you think is the most future proof, but stylish, way to save your text files?
