javascript - Do you really need a width on floated element? -


say have div (id="toolbar"), , inside toolbar have div (id="buttonholder") contains 2 buttons. if float #buttonholder right , don't set explicit width on it, kosher?

i've read on stack overflow should set width on floated element. buttons text might change, save apply, , don't want have adjust #buttonholder's width every time.

i thought setting #buttonholder's width auto, browser default seems unnecessary set it's width auto. i'm worried browser might not float #buttonholder way think should.

a change "save" "apply" isn't going take more room, honest.

in principle, yes should set width - if don't, have button float:left; , <div> float:right;. if don't set widths, they're not going take full screen width, elements put in below going try position in gap between two.

it idea have 100% width container element particular scenario prevent described effects.
