我想在一秒钟内让svg在侧面生长。我有这个代码

<!DOCTYPE html>
<html>
    <head>
        <title>Title of the document</title>
        <script src="js/plugin/jquery-2.1.4.min.js"></script>
        <style>
            /* Shorthand version */
            .hub-icon-container svg {
                position: relative;
                /* Firefox */
                -moz-transition: all 1s ease;
                /* WebKit */
                -webkit-transition: all 1s ease;
                /* Opera */
                -o-transition: all 1s ease;
                /* Standard */
                transition: all 1s ease;
            }
            .hub-icon-container svg:hover {
                width: 500px;  
                height: 500px;  
            }

        </style>

    </head>
    <body>

                </g>
            </svg>
        </a>
    </body>
</html>

但如果我将其悬停，这是有效的。我如何在页面加载后立即让它开始增长（超过1秒），或者我动态地将类附加到它上。如果我删除:hover，那么它只是开始完全增长，而不会动画化。有人知道怎么解决这个问题吗？

使用关键帧作为以下

/* Shorthand version */
.hub-icon-container svg {
position: relative;
/* Firefox */
-moz-transition: all 1s ease;
/* WebKit */
-webkit-transition: all 1s ease;
/* Opera */
-o-transition: all 1s ease;
/* Standard */
transition: all 1s ease;
}
.hub-icon-container svg:hover {
width: 500px;  
height: 500px;  
}
.hub-icon-container svg {
-webkit-animation: blowup 5s infinite; /* Safari 4+ */
-moz-animation:    blowup 5s infinite;/* Fx 5+ */
-o-animation:      blowup 5s infinite; /* Opera 12+ */
animation:         blowup 5s infinite;/* IE 10+, Fx 29+ */
}
