1. it is a warning, not an error 2. CSS 2.0 actually required floated elements to have a width declared. This requirement has been dropped from CSS 2.1 in favour of a shrink-to-fit algo. <http://www.w3.org/TR/2008/REC-CSS2-20080411/visuren.html#floats> vs <http://www.w3.org/TR/CSS21/visuren.html#floats> <http://www.w3.org/TR/CSS21/visudet.html#float-width> 3. it is not necessarily a bad practice to assign a width to a floated element. Depending on the content of the floated element, rendering engines may differ on how wide the floated element is. Older rendering engines have problems with width-less floated elements.
