When executing JQueryUI's slide
transition on an element with a CSS transform
the top half of the element is being hidden during the animation. Is there some way I can adjust my JQueryUI animation and/or CSS to prevent this from happening?
JSFiddle : I've created a JSFiddle with the appropriate code - http://jsfiddle.net/9dTkL/4/
To accomplish the vertical centering, I do the following:
<style>
#banner-welcome {
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
width: 100%;
top: 50%;
transform: translateY(-50%);
-ms-transform: translateY(-50%);
-o-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
</style>
The top
and transform
within the CSS allow the banner to fall into the center.
To perform the animation, I execute the following:
$('#banner-welcome').toggle(
'slide',
function()
{
document.location.href = "#/" + destination;
}
);
When the animation starts the top half of the #welcome-banner
disappears, and the bottom half animates. I've removed the transform
from the CSS and everything works great -- except that my banner is no longer centered.
I am performing the vertical centering this way due to a combination of AngularJS and ng-views
. I had previously used JavaScript to center the element, but adding the logic to the $(window).resize()
event caused problems in other ng-views
. I needed a way to isolate this to the specific ng-view
.
Is there something I can adjust with my animation or CSS that would not cause the top half of the banner to disappear?
toggle is removed as of 1.9: http://api.jquery.com/toggle-event/
so please use animate or slideDown or slideUp method
also the transform property doesn't need prefixes
#banner-welcome {
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
width: 100%;
top: 50%;
transform: translateY(-50%);
}
have you tried adding transform-origin property
#banner-welcome {
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
width: 100%;
top: 50%;
transform-origin: 50% 50% 0;
transform: translateY(-50%);
}
im not seeing the top part disappear in latest Firefox 24
