Thanks Justin and Miles for your ideas. It can take a looong time and a huge quantity of beer to disscuss them. I was asking for some other ideas just about the code, how to solve this problem technicaly not if this is a good idea to use one / two colums, tables or DIVS, print vs screen etc.
thanks anyway saludos aniceto lópez :: DYNAMICAL.BIZ web development & host services Barcelona - Spain -----Mensaje original----- De: Justin French [mailto:[EMAIL PROTECTED] Enviado el: miércoles, 27 de agosto de 2003 15:06 Para: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Asunto: Re: [PHP] dynamical balancing text in two colums To throw a huge spanner in the works: 1. tables are not intended for layout 2. devices other than a PC/Windows web browser may be more suited to q well structured XHTML based, table-less format with CSS for styling. 3. columns work well in a newspaper, but do not translate well to the web, since you have no idea where the bottom of the screen is... who wants to scroll down, only to discover this is half or one third of the text, having to scroll up again??? IF ANYTHING, structure/style your columns using DIVs/CSS, NOT tables... that way, for accessibility purposes, the content is still readable when read top-to-bottom, via something like a PDA, mobile/cell phone, text-to-speach converter, etc. Yes, i use columns in layout, but NOT to discuss one topic... each column is a div, and each div is styled with CSS to look like a column when styled, and each div discusses one topic... a long article would not be spread across two divs... this is a structural nightmare!!! You are trying to emulate another medium (print), rather than embracing another (web) which has a different set of rules. If you must break the text into two columns, try to do it with divs and style sheets, not tables, so that it's structurally not too far out of normal reading. Really though, do your readers want/need this??? I hate to think how bad this sort of ugly mark-up prints out!!!
