转换属性CSS3规模但坚持到底

Question

有没有人知道如何缩放图像但坚持底部？下面是我的代码,我的图像在中间缩放,但我需要它们粘在底部.

.animation_scale{
position:absolute;
top:150px;
left:55px;
display:block;
z-index:-10;
bottom : 0;}

.animation_scale img{
animation-name:animation_scale;
animation-duration:1s;
animation-timing-function:ease;
animation-delay:0s;
animation-iteration-count:1;
animation-direction:alternate;
animation-play-state:running;
animation-fill-mode: forwards;

    /* Firefox: */
-moz-animation-name:animation_scale;
-moz-animation-duration:1s;
-moz-animation-timing-function:ease;
-moz-animation-delay:0s;
-moz-animation-iteration-count:1;
-moz-animation-direction:alternate;
-moz-animation-play-state:running;
-moz-animation-fill-mode: forwards;

/* Safari and Chrome: */
-webkit-animation-name:animation_scale;
-webkit-animation-duration:1s;
-webkit-animation-timing-function:ease;
-webkit-animation-delay:0s;
-webkit-animation-iteration-count:1;
-webkit-animation-direction:alternate;
-webkit-animation-play-state:running;
-webkit-animation-fill-mode: forwards;}

@keyframes animation_scale {
0%   {
-webkit-transform:  scale(0.2) translate(0px);
-moz-transform:  scale(0.2) translate(0px);
-o-transform:  scale(0.2) translate(0px);}

100% {
-webkit-transform: scale(1.0) skew(0deg) translateY(-10px);
-moz-transform: scale(1.0) skew(0deg) translateY(-10px);
-o-transform: scale(1.0) skew(0deg) translateY(-10px);}}

@-moz-keyframes animation_scale /* Firefox */
{0%   {
-moz-transform:  scale(0.2) translate(0px);}

100% {
-moz-transform:  scale(1.0) translateY(-10px);}}

@-webkit-keyframes animation_scale{ /* Safari and Chrome */

0%   {
-webkit-transform:  scale(0.2) translate(0px);}

100% {
-webkit-transform:  scale(1.0) translateY(-10px);}}

Answer 1

使用 transform-origin center bottom

这是工作DEMO

Answer 2

transform-origin在transform应用了a的元素上使用属性.

它定义了转型的"中心"点:

-webkit-transform-origin: 50% 100%;
-moz-transform-origin: 50% 100%;
-o-transform-origin: 50% 100%;
transform-origin: 50% 100%;

要么

-webkit-transform-origin: center bottom;
-moz-transform-origin: center bottom;
-o-transform-origin: center bottom;
transform-origin: center bottom;
