使用 -webkit-background-clip 和 clip-path ,并配合 animation 属性,实现一个好看聚光灯效果。
可适用于页面加载或展示页面大标题内容。

.spotlight18{ color: #eaeaea; font-size: 40px; font-weight: 900; text-transform: uppercase; position: relative; } .spotlight18:before{ width: inherit; height: inherit; content: attr(data-cont); clip-path: ellipse(32px 32px at 0 50%); color: transparent; background-image: linear-gradient(90deg, #4158D0 0%, #C850C0 30%, #FFCC70 66%, #56e28d 100%); -webkit-background-clip: text; position: absolute; top: 0; left: 0; animation: spotlight18 8s linear infinite; } @keyframes spotlight18{ 0%{ clip-path: ellipse(32px 32px at 0 50%); } 50%{ clip-path: ellipse(32px 32px at 100% 50%); } 100%{ clip-path: ellipse(32px 32px at 0 50%); } } |
用 background-image 的 linear-gradient 拉出渐变背景,让文字颜色透明 color: transparent ,然后配合 -webkit-background-clip: text 给文字实现渐变效果,最后加上动画属性 animation 并设置 clip-path 参数就可以啦。
注意:这里使用的是 -webkit-background-clip ,而不是 background-clip 。
