DANDEV chia sẻ với các bạn cách làm hiệu ứng quay với button bằng css. Cụ thể ở đây mình dùng hiệu ứng rotate.

Phần HTML:

 <div class="downloads">
	 <a class="demobutton button" href="https://www.facebook.com/sharebacsic/" target="_blank" rel="nofollow noopener">Fanpage  </a>
	 <a class="button downloadbutton" href="https://dandev.net/download" target="_blank" >Download  </a>
</div>

Phần CSS:

 /* Start button download & demo */
.downloads a, .downloads span {
    margin-left:10px;
    text-decoration: none;
    background:none;
    font-size: 15px;
    color: #000;
}
.downloads .button:hover {
    box-shadow:none;
    color: #ff4422;
}
.downloads {
    height: 50px;
    font-weight:bold;
    display: flex;
    justify-content: center;
    align-items: center;
}
.button {
    position: relative;
    color: red;
    width: 150px;
    height: 50px;
    line-height: 50px;
    transition: all 0.3s;
    text-align: center;
}
.demobutton::before, .demobutton::after {
    content: '';
    position: absolute;
    width: 100%;
    height: 100%;
    bottom: 0;
    left: 0;
    z-index: 1;
    transition: all 0.3s;
    border: 2px solid red;
}
.downloadbutton::before, .downloadbutton::after {
    content: '';
    position: absolute;
    width: 100%;
    height: 100%;
    bottom: 0;
    left: 0;
    z-index: 1;
    transition: all 0.3s;
    border: 2px solid blue;
}
.button:hover::after {
    animation-name: rotatecw;
    animation-duration: 2s;
}
.button:hover::before {
    animation-name: rotateccw;
    animation-duration: 3s;
}
.button:hover::after, .button:hover::before {
    left: 50px;
    width: 50px;
    background:none;
    animation-iteration-count: infinite;
    animation-timing-function: linear;
}
@keyframes rotatecw {
    from {transform: rotate(0deg);}
    to {transform: rotate(360deg);}
}
@keyframes rotateccw {
    from {transform: rotate(0deg);}
    to {transform: rotate(-360deg);}
}
/* End button download & demo */
