Metrical rhythm generally involves precise arrangements of stresses or syllables into repeated patterns called feet within a line. In Modern English verse the pattern of stresses primarily differentiate feet, so rhythm based on meter in Modern English is most often founded on the pattern of stressed and unstressed syllables (alone or elided ).  In the classical languages , on the other hand, while the metrical units are similar, vowel length rather than stresses define the meter.  Old English poetry used a metrical pattern involving varied numbers of syllables but a fixed number of strong stresses in each line. 
A common pitfall of a CSS based columns layout is that the columns do not share a common height. Unlike a table based layout where the height of the table itself dictates the height of all of its columns, CSS columns are independent of one another in that respect. Now, this can be problematic (from a design standpoint) when you wish to style one of your CSS columns in a way that should extend all the way down to the end of the layout, such as giving a side column an explicit background color, a surrounding border etc.
