Question

尝试制作动画。但是Chrome上没有任何反应。显示普通标题。

*{
margin: 0;
height: 0;
box-sizing: border-box;
}

body{
font-family: "Lato", sans-serif;
font-weight: 400;
font-size: 16px;
line-height: 1.7;
color: #777;
padding: 30px;
}

header{
height: 95vh;
background-image: linear-gradient(to right bottom,rgba(126,213,111,0.8), rgba(40,180,131,0.8)),url(../img/hero.jpg);
background-size: cover;
background-position: top;
position: relative;

clip-path: polygon(0 0, 100% 0, 100% 75%, 0 100%);
}

.text-box{
position: absolute;
top: 30%;
left: 50%;
transform: translate(-40%,-50%);
}

.logo-box{
position: absolute;
top: 40px;
left: 40px;

}

.logo{
height: 35px;
}

.heading-primary{
color: #fff;
text-transform: uppercase;
}

.heading-primary-main{
letter-spacing: 35px;
font-weight: 400;
font-size: 60px;

animation-name: moveInLeft;
animation-duration: 4s;
animation-iteration-count: 3;
/*animation-delay: 3s;*/
}

.heading-primary-sub{
display: block;
letter-spacing: 17.5px;
font-weight: 700;
font-size: 20px;
}

@-webkit-keyframes moveInLeft{
0% {
opacity: 0;
transform: translateX(-100px);
}
80%{
transform: translateX(10px);
}
100%{
opacity: 1;
transform: translateX(0);
}
}

我想执行动画以使标题从左向右移动，但是按原样显示标题时没有任何反应。我使用@-webkit-keyframes仍然没有任何反应。使用@keyframes没有任何反应。浏览器（Chrome）是否有问题？有人可以帮我吗？我最近开始学习CSS中的动画，但是这种错误确实无助于进一步学习。

Answer 1

有了这些更改，它对我来说非常好-：

.heading-primary {
  animation: play 4s steps(10) infinite;
}

@keyframes play {
  from {
    transform: translate(-100px);
  }
  to {
    transform: translate(0px);
  }
}

Answer 2

您可以使用transform代替margin-left：

*{
margin: 0;
height: 0;
box-sizing: border-box;
}

body{
font-family: "Lato", sans-serif;
font-weight: 400;
font-size: 16px;
line-height: 1.7;
color: #777;
padding: 30px;
}

header{
height: 95vh;
background-image: linear-gradient(to right bottom,rgba(126,213,111,0.8), rgba(40,180,131,0.8)),url(../img/hero.jpg);
background-size: cover;
background-position: top;
position: relative;

clip-path: polygon(0 0, 100% 0, 100% 75%, 0 100%);
}

.text-box{
position: absolute;
top: 30%;
left: 50%;
transform: translate(-40%,-50%);
}

.logo-box{
position: absolute;
top: 40px;
left: 40px;

}

.logo{
height: 35px;
}

.heading-primary{
color: #fff;
text-transform: uppercase;
}

.heading-primary-main{
letter-spacing: 35px;
font-weight: 400;
font-size: 60px;

animation-name: moveInLeft;
animation-duration: 4s;
animation-iteration-count: 3;
/*animation-delay: 3s;*/
}

.heading-primary-sub{
display: block;
letter-spacing: 17.5px;
font-weight: 700;
font-size: 20px;
}

@-webkit-keyframes moveInLeft{
0% {
opacity: 0;
margin-left: -100%;
}
100%{
opacity: 1;
margin-left: 0;
}
}
