css:

.hidemsg {
    width: 270px;
    height: 40px;
    line-height: 28px;
    background: #ff5656;
    text-align: center;
    /* display: none; */
    border-radius: 5px;
    overflow: hidden;
}

.hidemsg div {
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    margin: auto;
    pointer-events: none;
    background-color: #ffffff;
    -webkit-border-radius: 100%;
    -moz-border-radius: 100%;
    -o-border-radius: 100%;
    -ms-border-radius: 100%;
    border-radius: 100%;
    -webkit-animation-fill-mode: both;
    -moz-animation-fill-mode: both;
    -ms-animation-fill-mode: both;
    -o-animation-fill-mode: both;
    animation-fill-mode: both;
    display: inline-block;
    width: 204px;
    height: 204px;
    -webkit-animation: ball-scale 1s 0s ease-in-out infinite;
    -moz-animation: ball-scale 1s 0s ease-in-out infinite;
    -ms-animation: ball-scale 1s 0s ease-in-out infinite;
    -o-animation: ball-scale 1s 0s ease-in-out infinite;
    animation: ball-scale 1s 0s ease-in-out infinite;
}

@-webkit-keyframes ball-scale {
    0% {
        -webkit-transform: scale(0);
        transform: scale(0)
    }
    100% {
        -webkit-transform: scale(1);
        transform: scale(1);
        opacity: 0
    }
}

@keyframes ball-scale {
    0% {
        -webkit-transform: scale(0);
        transform: scale(0)
    }
    100% {
        -webkit-transform: scale(1);
        transform: scale(1);
        opacity: 0
    }
}

.hidemsg p {
    margin: 0;
    line-height: 40px;
    color: #ffffff;
    font-weight: 700;
    font-size: 16px;
}

.hidemsgAfter {
    width: 293px;
    position: relative;
    left: 10px;
    top: 10px;
    border-radius: 5px;
    overflow: hidden;
    cursor: pointer;
}

.hidemsgAfter :after {
    content: '';
    position: absolute;
    top: 11px;
    right: 15px;
    display: block;
    border-top: 8px solid transparent;
    border-bottom: 8px solid transparent;
    border-left: 8px solid #ff5656;
}

动画中图片放大是使用transform:scale()方法：

img {
    transform:scale(1.5);
}
