jquery - Can a td be the relatively positioned ancestor of an absolutely positioned element? -

-

i have image want transition image. child of containing td element.

so first style td .css('position', 'relative')

then create second image , give properties:

var img = $('<image src="a.png" />')    .css({       position: 'absolute',       top: 0,       left: 0,       opacity: 0,       'z-index': 1    })    .appendto($td) ;

finally animate old image , new one:

img.fadein(1000); oldimg.fadeout(1000);

at end of animation can remove old image , reset css properties.

now, works great in ie7, firefox 5 sending replacement image top left of div containing table instead of overlaying existing image in td. correct behavior? td not valid relatively positioned ancestor because it's not block element or that?

suggestions of better ways make 1 image fade welcome.

update

i switched having image inline usual, added negative top margin equal own height (since image fills cell, displays underneath image want replace). worked beautifully , didn't require absolute positioning.

so first style td .css('position', 'relative')

check out wc3 css 2.1 specification : visual formatting model : 'position' property:

the effect of 'position:relative' on table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, , table-caption elements is undefined.

a common workaround wrap div position:relative around inside td.

are sure need using tables this?

actionscript 3 - TweenLite does not work with object -

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
