css animation-fill-mode 向前改变元素的不透明度
css animation-fill-mode foward changes element opacity
当图像完成其动画并向前填充时图像出现问题,它的不透明度低于我正常加载图像(动画被移除)
.header-container .col-2 {
display: flex;
justify-content: center;
align-items: center;
width: 50%;
z-index: -1;
}
.header-container .col-2 img {
opacity: 0; //
animation: 0.5 header ease 1.25s; // these three lines seem to be the problem
animation-fill-mode: forwards; //
}
@keyframes header {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
我查看了浏览器上的样式 (chrome),但无法弄清楚为什么会这样
图中是不同之处 + chrome 样式
img on right has slightly lower opacity
感谢任何建议/帮助
animation: 0.5 header ease 1.25s;
没有时间单位的 0.5
被解释为 animation-iteration-count
,如果设置为 0.5
,则表示:"Run my animation halfways."
你想要的是:name, duration, easing, delay, fill-mode
使用:
animation: header 0.5s ease 1.25s forwards;
并使用 s
或 ms
单位作为持续时间值。
这是动画 shorthand 订单的提醒:
name, duration, easing, delay, iteration-count, direction, fill-mode
.header-container .col-2 {
display: flex;
justify-content: center;
align-items: center;
width: 50%;
z-index: -1;
background: url("https://placehold.it/100x100/00f");
}
.header-container .col-2 img {
