- 打字效果
文章图片
通过 steps() 属性来实现分割文本的效果。首先，你必须指定 step() 中传入的数量，在这个例子中就是文本的长度。
接着，第二步，我们使用 @keyframes 去声明什么时候开始执行动画
Typing effect for text.typing {
height: 80vh;
display: flex;
align-items: center;
justify-content: center;
}
.typing-effect {
width: 22ch;
white-space: nowrap;
overflow: hidden;
border-right: 3px solid;
font-family: monospace;
font-size: 2em;
animation: typing 2s steps(22), effect .5s step-end infinite alternate;
}@keyframes typing {
from {
width: 0;
}
}@keyframes effect {
50% {
border-color: transparent;
}
}- 透明图片阴影效果
文章图片
说明：
使用：drop-shadow
drop-shadow 的工作方式是，其遵循给给定图片的 Alpha 通道。因此阴影是基于图片的内部形状，而不是显示在图片外面。

}- 侧边栏的 Hover 效果
文章图片
Hover over the sidebar
Also work with Tab selector (for accessibility)
.css-dynamic-sidebar {

}- 使用 first-letter 实现首字母大写
文章图片
here we target thewrapper and select the p element. then append first-of-type and target first-letter specifically. you can then reuse the same option in other parts of your design by changing the wrapper variable
.content-section p:first-of-type::first-letter {
color: #f3f3f3;
float:left;
font-size: 4rem;
line-height: 4vw;
padding-right: 8px;
/* border: 0.25em double;
*/
