If you like to design visually and have an app break the content up for you, then you might want to try Softpress Freeway 5 Pro.
Quoted from their website:
REAL CSS CONTROL
Freeway 5 Pro can be used to create CSS (table-less) page layouts using absolute positioning, and exposes the real power of CSS through relative positioning, percentage scaling of all elements, partial styles, and more, and all with the legendary Freeway WYSIWYG design view.
