html5 - CSS3 transform:rotate on hover -


i have nice animation set have bullet shooting star rotates after hover on gun, works should but.......

after take mouse off gun star rotates other way, not :( ideas how stop?

i have tried use 'active' instead doesn't work animation.

css

#star {   width:48px;   height:49px;   position:absolute;   z-index:5;   left:922px;   top:63px;   -webkit-transition: 4s ease-out;   -moz-transition: 4s ease-out;   -o-transition: 4s ease-out;   -ms-transition: 4s ease-out;   transition: 4s ease-out; }     #gun:hover ~ #star {   -webkit-transform:rotatez(340deg);   -moz-transform:rotatez(340deg);   -o-transform:rotatez(340deg);   -ms-transform:rotatez(340deg);   transform:rotatez(340deg);   -webkit-transition-delay: 1s;   -moz-transition-delay: 1s;   -o-transition-delay: 1s;   -ms-transition-delay: 1s;   transition-delay: 1 }

the nature of :hover css selector applies when hover happening on source element. reverse triggered when user no longer hovers because :hover no longer applies. there 2 ways achieve want:

  1. use animations instead. animations have animation-fill-mode, when set forwards causes element retain it's computed values set last keyframe encountered during execution. mdn has more info it.

    here's how you'd in css:

    #gun:hover ~ #star {     -webkit-animation: rotate 4s forwards;     animation: rotate 4s forwards; } @-webkit-keyframes rotate {     100% {         -webkit-transform: rotate(360deg);     } } @keyframes rotate {     100% {         transform: rotate(360deg);     } }

  2. if don't want use animations, need write javascript. use hover event, because events don't depend on current state :hover does. notice moved transition-delay css #star, can apply element whole time no effect. i've used jquery succinctness:

    javascript:

    $('#gun').hover(function() {   $('#star').css('transform', 'rotatez(340deg)'); });

    css:

    #star {     width: 50px;     -webkit-transition: 4s ease-out;     -moz-transition: 4s ease-out;     -o-transition: 4s ease-out;     -ms-transition: 4s ease-out;     transition: 4s ease-out;     -webkit-transition-delay: 1s;     -moz-transition-delay: 1s;     -o-transition-delay: 1s;     -ms-transition-delay: 1s;     transition-delay: 1 }

    --or--

    you can achieve vanilla javascript too. used css class called shot apply transform, since lacking jquery's cross-browser , cleaner way:

    javascript:

    var gun = document.getelementbyid('gun'); var star = document.getelementbyid('star');  gun.onmouseover = function () {     star.classname = 'shot'; };

    css: (in addition css jquery example)

    #star.shot {     -webkit-transform:rotatez(340deg);     -moz-transform:rotatez(340deg);     -o-transform:rotatez(340deg);     -ms-transform:rotatez(340deg);     transform:rotatez(340deg); }

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
