CSS3 animation scale

animationcss

提问by Mauro74

I'm trying to animate a div so that when the page load it has scale(0,0) and animates to scale(1,1). The problem I have is that once the animation takes effect the div scales to 0 again. What I want is the div to animate to scale(1,1) and staying like that. Here's my CSS code

我正在尝试为 div 设置动画,以便在页面加载时它具有缩放(0,0)并动画缩放(1,1)。我遇到的问题是,一旦动画生效,div 将再次缩放为 0。我想要的是 div 动画缩放(1,1)并保持这样。这是我的 CSS 代码

@-moz-keyframes bumpin {
    0% { -moz-transform: scale(0,0); }
    100%   { -moz-transform: scale(1,1); }
}

.landing .board {
    -moz-transform: scale(0,0);
    -moz-transform-origin: 50% 50%;
}

.landing .board {
    -moz-animation-name: bumpin;
    -moz-animation-duration: 1s;
    -moz-animation-timing-function: ease;
    -moz-animation-delay: 0s;
    -moz-animation-iteration-count: 1;
    -moz-animation-direction: normal;
}

What am I doing wrong?

我究竟做错了什么?

Thanks in advance
Mauro

You're looking for animation-fill-mode:forwardswhich applies the last keyframe of the nimation to the element when the animation is done. https://developer.mozilla.org/en/CSS/animation-fill-mode

您正在寻找animation-fill-mode:forwards哪个在动画完成时将动画的最后一个关键帧应用于元素。https://developer.mozilla.org/en/CSS/animation-fill-mode

-moz-animation-fill-mode: forwards

Another way of doing this: If all you want to do is animate an element to scale, you don't need to use keyframes. transitions will suffice.

另一种方法是:如果您只想为要缩放的元素设置动画,则不需要使用关键帧。过渡就足够了。

.landing-board {
  -moz-transition: all 1s ease;
  /* all other css properties */
}
.landing-board.animated {
  -moz-transform: scale(1.1);
}

And very little javascript to add the related class to your element: (Here i'm using jquery but it could be done in any other framework or pure javascript)

很少有 javascript 可以将相关类添加到您的元素中:(这里我使用的是 jquery,但它可以在任何其他框架或纯 javascript 中完成)

$(window).load(function() {
  $('.landing-board').addClass('animated');
});
