我正在尝试应用在这段视频here中看到的很酷的“毛刺效果”:
但是,我似乎无法使该动画正常工作。这是我尝试将效果应用到的标题元素:
<h1 class="header-block-heading-primary">Web Developer</h1>
这是SCSS:
.header-block-heading-primary {
// animation: glitch-effect 3s infinite;
position: relative;
&::before,
&::after {
position: absolute;
left: 0;
top: 0;
content: "";
display: block;
height: 100%;
width: 100%;
z-index: -1;
}
&::before {
color: red;
animation: glitch-effect 3s infinite;
}
&::after {
color: blue;
animation: glitch-effect 2s infinite;
}
}
这是动画:
@keyframes glitch-effect {
0% {
left: -3px;
top: -3px;
}
25% {
left: 3px;
top: 0px;
}
50% {
left: -2px;
top: 3px;
}
75% {
left: 2px;
top: -2px;
}
100% {
left: 0px;
top: -3px;
}
}
这是输出的CSS:
.header-block-heading-primary {
position: relative;
}
.header-block-heading-primary::before,
.header-block-heading-primary::after {
position: absolute;
left: 0;
top: 0;
content: "";
display: block;
height: 100%;
width: 100%;
z-index: -1;
}
.header-block-heading-primary::before {
color: red;
-webkit-animation: glitch-effect 3s infinite;
animation: glitch-effect 3s infinite;
}
.header-block-heading-primary::after {
color: blue;
-webkit-animation: glitch-effect 2s infinite;
animation: glitch-effect 2s infinite;
}
我遵循了与教程相同的设置,甚至引用了我的一些旧项目,研究了::before
和::after
的使用,并且它们在几乎相同的代码下也可以正常工作(对于伪元素)。
我只尝试了一个分号,所以:before
和:after
无效。我将动画直接添加到元素本身(如// animation: glitch-effect 3s infinite;
选择器下方的注释.header-block-heading-primary
所示),并且效果很好,因此我被认为是::before
和::after
个元素不起作用。同样,在嵌套的SCSS中手动添加-webkit-
也不起作用。
我已经在网站上查看了其他多个帖子,但找不到可以帮助我解决此问题的答案。因此,对此的任何帮助将不胜感激!

您的动画正在工作,但是您需要设置::after
和::before
content:"Web Developer"
。您可以在摘要中显示效果。
.header-block-heading-primary {
position: relative;
}
.header-block-heading-primary::before,
.header-block-heading-primary::after {
position: absolute;
left: 0;
top: 0;
content: "Web Developer";
display: block;
height: 100%;
width: 100%;
z-index: -1;
}
.header-block-heading-primary::before {
color: red;
animation: glitch-effect 3s infinite;
}
.header-block-heading-primary::after {
color: blue;
animation: glitch-effect 2s infinite;
}
@keyframes glitch-effect {
0% {
left: -3px;
top: -3px;
}
25% {
left: 3px;
top: 0px;
}
50% {
left: -2px;
top: 3px;
}
75% {
left: 2px;
top: -2px;
}
100% {
left: 0px;
top: -3px;
}
}
<h1 class="header-block-heading-primary">Web Developer</h1>
这是在我的页面中运行的sass代码,请尝试使用此代码。
.header-block-heading-primary {
position: relative;
&::before,
&::after {
position: absolute;
left: 0;
top: 0;
content: "Web Developer";
display: block;
height: 100%;
width: 100%;
z-index: -1;
}
&::before {
color: red;
animation: glitch-effect 3s infinite;
}
&::after {
color: blue;
animation: glitch-effect 2s infinite;
}
}
@keyframes glitch-effect {
0% {
left: -3px;
top: -3px;
}
25% {
left: 3px;
top: 0px;
}
50% {
left: -2px;
top: 3px;
}
75% {
left: 2px;
top: -2px;
}
100% {
left: 0px;
top: -3px;
}
}
谢谢。

我明白了!标题部分的背景图片与::before
和::after
冲突,因此我只需要在标题中添加更高的z-index
即可!
.header-block-heading-primary {
position: relative;
z-index: 20;
&::before {
position: absolute;
left: 0;
top: 0;
height: 100%;
width: 100%;
content: "Web Developer";
z-index: -1;
}
&::after {
content: "Web Developer";
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: -1;
}
&::before {
color: #ff00c1;
animation: glitch-effect 3s infinite;
}
&::after {
color: #3498db;
animation: glitch-effect 2s infinite;
}
&:hover::before {
animation: glitch-effect 1s infinite;
}
&:hover::after {
animation: glitch-effect 2s infinite;
}
}
