We aught to define the cases when body can be considered invisible (also style="visibility:hidden" ?) 101398 1 dburns 2014-02-25 20:07:06 +0000 Add a MUST on that BODY is always visible. 102334 2 dburns 2014-03-13 23:11:39 +0000 Fixed in https://dvcs.w3.org/hg/webdriver/rev/81cc3d3b5f5f 103041 3 botalov.andrey 2014-03-27 20:27:22 +0000 Why body should always be considered visible? IMO body doesn't look visible in case of: <body style="display:none">....</body> 103044 4 luke.semerau 2014-03-27 20:43:10 +0000 view the browser on an html page with that. What do you see? You see a big blank white page... you "see" it! :) body is 'specail' 103045 5 luke.semerau 2014-03-27 20:43:50 +0000 special* ha! 108841 6 ato 2014-07-10 10:44:58 +0000 Allow me to shed some light on why the body should always be considered visible. In the CSS specification the HTML and BODY elements are considered special snowflakes. Based on an order of preference (which always prefers the ancestral element, that is the HTML element) if background-color or background-image is set, that gets transposed on to the browser's painting canvas. In effect this means that what you see on the screen in a document containing <body></body> (empty body) is always visible because the default value of background-color for the BODY element is "transparent", which the CSS spec defines as user agent specific behaviour. In the case of desktop browsers that means falling back to base.css (or the equivalent) which defines the colour white to be the default. 108842 7 ato 2014-07-10 10:45:30 +0000 The relevant spec prose around this is defined here: http://dev.w3.org/csswg/css-backgrounds/#special-backgrounds
