css - Don't start animation until in view -


i wondering how stop animation starting until has been scrolled in full view. using plugin, animate.css dan eden animate elements. have added animation , works need know how make start once in full view.

this code element have animated using class:

<div class="animated fadeinup" id="enter-title"><img src="/images/welcome-text/enter.png" width="473" height="227"/></div>

this animation code:

@-webkit-keyframes fadeinup { 0% {     opacity: 0;     -webkit-transform: translatey(20px); }  100% {     opacity: 1;     -webkit-transform: translatey(0); }  .animated.fadeinup { -webkit-animation-name: fadeinup; -moz-animation-name: fadeinup; -o-animation-name: fadeinup; animation-name: fadeinup; }

if you're looking hold animation until image scrolled view use little jquery so:

working example

jquery

$(window).scroll(function () {     var y = $(window).scrolltop(),         x = $('.animated').offset().top - 200;     if (y > x) {         $('.animated').addclass('fadeinup').removeclass('fadeoutdown');     } else {         $('.animated').removeclass('fadeinup').addclass('fadeoutdown');     } });

css

.animated {     -webkit-animation-fill-mode:both;     -moz-animation-fill-mode:both;     -ms-animation-fill-mode:both;     -o-animation-fill-mode:both;     animation-fill-mode:both;     -webkit-animation-duration:1s;     -moz-animation-duration:1s;     -ms-animation-duration:1s;     -o-animation-duration:1s;     animation-duration:1s;     opacity:0;                /*** important bit ***/ } .animated.hinge {     -webkit-animation-duration:2s;     -moz-animation-duration:2s;     -ms-animation-duration:2s;     -o-animation-duration:2s;     animation-duration:2s; } @-webkit-keyframes fadeinup {     0% {         opacity: 0;         -webkit-transform: translatey(20px);     }     100% {         opacity: 1;         -webkit-transform: translatey(0);     } } @-moz-keyframes fadeinup {     0% {         opacity: 0;         -moz-transform: translatey(20px);     }     100% {         opacity: 1;         -moz-transform: translatey(0);     } } @-o-keyframes fadeinup {     0% {         opacity: 0;         -o-transform: translatey(20px);     }     100% {         opacity: 1;         -o-transform: translatey(0);     } } @keyframes fadeinup {     0% {         opacity: 0;         transform: translatey(20px);     }     100% {         opacity: 1;         transform: translatey(0);     } } .fadeinup {     -webkit-animation-name: fadeinup;     -moz-animation-name: fadeinup;     -o-animation-name: fadeinup;     animation-name: fadeinup; } @-webkit-keyframes fadeoutdown {     0% {         opacity: 1;         -webkit-transform: translatey(0);     }     100% {         opacity: 0;         -webkit-transform: translatey(20px);     } } @-moz-keyframes fadeoutdown {     0% {         opacity: 1;         -moz-transform: translatey(0);     }     100% {         opacity: 0;         -moz-transform: translatey(20px);     } } @-o-keyframes fadeoutdown {     0% {         opacity: 1;         -o-transform: translatey(0);     }     100% {         opacity: 0;         -o-transform: translatey(20px);     } } @keyframes fadeoutdown {     0% {         opacity: 1;         transform: translatey(0);     }     100% {         opacity: 0;         transform: translatey(20px);     } } .fadeoutdown {     -webkit-animation-name: fadeoutdown;     -moz-animation-name: fadeoutdown;     -o-animation-name: fadeoutdown;     animation-name: fadeoutdown; }

i added additional animation fade image out when scroll up, optional, think makes nice effect.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
