"if" doesn't produce a loop - it's just a conditional check. Assuming your images are stored in an array, you can use any of a number of methods to loop them. * you could do .each_with_index and then start a new row on mod-3 of the index * you could use .each_slice(3) and iterate the returned array of three * you could (if you like it clunky) just use .each maintain your own counter and do your next row operations when it gets to a multiple of 3 http://www.ruby-doc.org/core/classes/Enumerable.html > or is this better acheived with css? Probably (for all sorts of "tables are for tabular data" reasons). But the problem of working out how to tell the element it's a new row will be very similar to using a table (unless you rely on overflow wrapping in a fixed-size container). -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
