html - 动画时长应该是相对于高度和宽度的

我有一个高度和宽度是动态的 div。我正在尝试为该 div 添加一个虚线动画边框。我面临的问题是动画持续时间与高度和宽度无关。即无论高度和宽度如何,它的动画在所有 Angular 落都应该以相同的速度

  .dynamic {
position: absolute;
height: 30px;
width: 300px;
overflow: hidden
}
.dynamic::before {
animation: slideDash 2.5s infinite linear;
position: absolute;
content: '';
left: 0;
right: 0;
outline: 1px dashed #fff;
box-shadow: 0 0 0 1px rgb(23, 163, 102);
width: 200%;
}
.dynamic::after {
animation: slideDash 2.5s infinite linear reverse;
position: absolute;
content: '';
right: 0;
bottom: 0;
outline: 1px dashed #fff;
left: 0;
box-shadow: 0 0 0 1px rgb(23, 163, 102);
width: 200%;
}
.dynamic div::before {
animation: slideDashRev 2.5s infinite linear reverse;
position: absolute;
content: '';
top: 0;
bottom: 0;
outline: 1px dashed #fff;
box-shadow: 0 0 0 1px rgb(23, 163, 102);
height: 200%;
}
.dynamic div::after {
animation: slideDashRev 2.5s infinite linear;
position: absolute;
content: '';
top: 0;
bottom: 0;
outline: 1px dashed #fff;
right: 0;
box-shadow: 0 0 0 1px rgb(23, 163, 102);
height: 200%;
}
@keyframes slideDash {
from {
transform: translateX(-50%);
}
to {
transform: translateX(0%);
}
}
@keyframes slideDashRev {
from {
transform: translateY(-50%);
}
to {
transform: translateY(0%);
}
}
<div class="dynamic">
<div></div>
</div>

最佳答案

只是修正动画的方向

.dynamic {
position: relative;
width: 300px;
height: 30px;
overflow: hidden;
color: red;
}
.dynamic .line {
width: 100%;
height: 100%;
display: block;
position: absolute;
}
.dynamic .line:nth-of-type(1) {
-webkit-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
}
.dynamic .line:nth-of-type(2) {
-webkit-transform: rotate(90deg);
-ms-transform: rotate(90deg);
transform: rotate(90deg);
margin-left: -164px; /* margin-left=(minus)((height+width)/2)-(border-width) */
}
.dynamic .line:nth-of-type(3) {
-webkit-transform: rotate(180deg);
-ms-transform: rotate(180deg);
transform: rotate(180deg);
}
.dynamic .line:nth-of-type(4) {
-webkit-transform: rotate(270deg);
-ms-transform: rotate(270deg);
transform: rotate(270deg);
margin-left: 164px; /* margin-left=((height+width)/2)-(border-width) */
}
.dynamic .line:nth-of-type(1) i, .dynamic .line:nth-of-type(3) i {
-webkit-animation: move 2.5s infinite linear reverse;
animation: move 2.5s infinite linear reverse;
}
.dynamic .line:nth-of-type(2) i, .dynamic .line:nth-of-type(4) i {
-webkit-animation: move 2.5s infinite linear;
animation: move 2.5s infinite linear;
}
.dynamic .line i {
left: 0;
top: 0;
width: 200%;
display: block;
position: absolute;
border-bottom: 1px dashed;
}
.dynamic .text {
width: 100%;
line-height: 30px;
display: block;
text-align: center;
position: absolute;
font-size: 18px;
}
@-webkit-keyframes move {
from {
-webkit-transform: translateX(0%);
transform: translateX(0%);
}
to {
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
}
}
@keyframes move {
from {
-webkit-transform: translateX(0%);
transform: translateX(0%);
}
to {
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
}
}
<body>
<div class="dynamic">
<div class="line"><i></i>
</div>
<div class="line"><i></i>
</div>
<div class="line"><i></i>
</div>
<div class="line"><i></i>
</div>
<div class="text">Same Direction!!</div>
</div>

</body>
