html - 可调整大小图像上的工具提示位置

Question

首先，我不是 html/ccs 编码方面的专家。我想使用来自(见下文)http://codepen.io/ianfarb/pen/qkpJH 的代码片段但在此示例中，工具提示的图像和位置是固定的。就我而言，我希望在调整浏览器宽度大小时调整图像大小。此外，工具提示必须保持在正确的位置。有什么建议么？

              position:absolute;
              background:rgba(255,255,255,.5);}

Answer 1

为此，您需要更改一些内容(见下文):

对背景图像进行少量更改以使其响应:

#container {
    background: url(https://lh3.ggpht.com/PQXITv6h0hTZLqlvlni7RSN2rE70QytYeNAtngBc3wKQuq8g5gH28EUDqYKgCPkWfQ=h900-rw) no-repeat;
    background-repeat: no-repeat;
    background-size: contain;
    background-position: center;
    height: 400px;
    margin: 25px auto;
    width: 600px;
    position: relative;
    max-width: 100%;
}

指定每个点的位置:

#first   { 
    left: 5%;
    top: 95px;
 }

#second   { 
    left: 40%;
    top: 235px;
}

#third   {
    left: 90%;
    top: 135px;
}
