css样式:
.typing{ font-size: 1rem; padding-top: 6%; margin-bottom: 5%; font-weight: normal; letter-spacing: .3rem; -webkit-animation: type 2s steps(50, end) forwards; animation: type 2s steps(50, end) forwards; } .typing-item{ text-align: center; color: black; width:100%; white-space:nowrap; overflow:hidden; } @-webkit-keyframes type{ from { width: 0;} } @keyframes type{ from { width: 0;} }
缺点:只能实现一行式的打字效果,无法打出一段落文字

调用Typed.js
var string = $('#content').val(); $('#content-item').typed({ strings: [" " + string], typeSpeed: 50, backDelay: 800, loop: false, loopCount: false });

最后,发现实现打字效果还是蛮简单的对吧,css的思路是利用width和overflow:hidden,动画让宽度变宽实现像打字的样式,但是样式有限,不能实现多行显示。js/jquery,普遍都是先得到字的内容,然后再逐字往容器中添加文字。问题不难,主要是要善于思考!!
以上这篇打字效果动画的4种实现方法(超简单)就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持创新互联。
