css3动画不断恢复到原始状态

使用CSS 3动画但由于某些原因,所有动画在执行后都会返回其原始状态.

在这种情况下,我希望图像在动画之后保持比例(1),并且我的文本在img动画之后显示,但之后保持.

.expanding-spinning {
   -webkit-transform: scale(.4);
   -webkit-transition-timing-function: ease-out;
   -webkit-transition-duration: 500ms;
   animation-duration: 500ms;
}

.expanding-spinning {
  -webkit-animation: spin2 1.4s ease-in-out alternate;
  animation: spin2 1.4s ease-in-out alternate;
  -webkit-animation-delay: 2s;
  animation-delay: 2s;
}

@-webkit-keyframes spin2 {
  0% { -webkit-transform: rotate(0deg) scale(.4);}
  100% { -webkit-transform: rotate(360deg) scale(1);}
}
@-keyframes spin2 {
  0% { transform: rotate(0deg) scale(.4);}
  100% { transform: rotate(360deg) scale(1);}
}

@-webkit-keyframes fadeInFromNone {
  0% {
    display:none; 
    opacity: 0;
  }

  100% {
    display: block; 
    opacity: 1;
  }
}

.slogan {
  display: block;
  opacity: 1;
  -webkit-animation-duration: 2s;
  -webkit-animation-name: fadeInFromNone;
  -webkit-animation-delay: 3.5s;
}

解决方法

您需要添加规则-webkit-animation-fill-mode：forwards;到你的动画.

此外,关于文本动画：为可见性属性设置动画而不是显示属性

FIDDLE

.expanding-spinning {
  -webkit-animation: spin2 1.4s ease-in-out;
  -moz-animation: spin2 1.4s linear normal;
  -o-animation: spin2 1.4s linear;
  -ms-animation: spin2 1.4s linear;
  animation: spin2 1.4s ease-in-out alternate;
  -webkit-animation-delay: 2s;
  animation-delay: 2s;
    -webkit-animation-fill-mode: forwards; /* <--- */
}
@-webkit-keyframes fadeInFromNone {
    0% {
        visibility:hidden; 
        opacity: 0;
    }

    100% {
        visibility: visible; 
        opacity: 1;
    }
}

.slogan {
    visibility:hidden;
    opacity: 1;
    -webkit-animation-duration: 2s;
    -webkit-animation-name: fadeInFromNone;
    -webkit-animation-delay: 3.4s;
    -webkit-animation-fill-mode: forwards; /* <--- */
}

end of the animation,
