MasterNik / 01 июля 2019 г. / 24588 / Время чтения 10 мин.

Предлагаю вашему вниманию 9 видов бесплатных примеров HTML анимации границ блока контента на CSS.

И так, поехали:

1. Анимированная трассировка границ

Это та область, за пределами которой вам следует мыслить

HTML

<div class="box">
 <div class="content">
 <h1>Это та область, за пределами которой вам следует мыслить</h1> 
 </div>
</div>

CSS

.box
{
 width: 300px;
 margin: 0 auto;
 padding: 2px;
 background-color: #eaab00; /* gold */
 /* Single pixel data uri image http://jsfiddle.net/LPxrT/ 
 /* background-image: gold, gold, white */
 background-image: url('data:image/gif;base64,R0lGODlhAQABAPAAAOqrAP///yH5BAAAAAAALAAAAAABAAEAAAICRAEAOw=='), url('data:image/gif;base64,R0lGODlhAQABAPAAAOqrAP///yH5BAAAAAAALAAAAAABAAEAAAICRAEAOw=='),
url('data:image/gif;base64,R0lGODlhAQABAPAAAP///////yH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==');
 background-repeat: no-repeat;
 background-size: 0 2px, 0 100%, 0% 2px;
 background-position: top center, top center, bottom center;
 -webkit-animation: drawBorderFromCenter 4s;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes drawBorderFromCenter {
 0% {
 background-size: 0 2px, 0 0, 100% 100%;
 }
 20% {
 background-size: 100% 2px, 100% 0, 100% 100%;
 }
 66%
 {
 background-size: 100% 2px, 100% 98%, 100% 100%;
 }
 99%
 {
 background-size: 100% 2px, 100% 98%, 0 2px;
 }
} 
 .content

 padding: 2em;
 text-align: center;
 text-transform: uppercase;
}
