地图HTML问题中的area href标记

我在html格式的图像中使用了map标记。网站链接：www.quadrotian.com

这里的问题是，单击时显示的社交平台符号会转到与站点地址连接的地址。代码如下：

<div class="subscribe">
    <h2>Follow Us : </h2>
    <div class="contact-form">
        <center>
            <img src="images/socialbuttons.png" usemap="#follow" hidefocus="true" style="outline: none;">
            <map name="follow" style="outline: none;">
                <area shape="circle" coords="49,23,19" href="www.instagram.com/Quadrotian" target="_blank" alt="Instagram" style="outline: none;">
                <area shape="circle" coords="97,23,19" href="www.facebook.com/Quadrotian" target="_blank" alt="Facebook" style="outline: none;">
                <area shape="circle" coords="149,23,19" href="www.pinterest.com/Quadrotian" target="_blank" alt="Pinterest" style="outline: none;">
                <area shape="circle" coords="201,23,19" href="www.twitter.com/Quadrotian" target="_blank" alt="Twitter" style="outline: none;">
                <area shape="circle" coords="251,23,19" href="www.plus.google.com/Quadrotian" target="_blank" alt="Google Plus" style="outline: none;">
                <area shape="circle" coords="303,23,19" href="#" alt="LinkedIn">
            </map>
        </center>
    </div>
</div>
