如何使工具提示拉伸以适合文本(没有预定义的宽度)

Question

因此，我有一个工具提示，我希望它伸展，以适应所有的文本在其中。我实际上有大约30个工具提示，我不想手动修改它们(我试过了，但它没有工作，所以我不知道我会怎么做)。这是我的代码：

​

.programButton {
    width: 1000px;
    height: 100px;
    background: #EAEAEA;
    border: 1px solid black;
    text-align: left;
}
#programButtonText, .programButtonExtra {
    font-family: 'Open Sans', sans-serif;
    font-size: 34px;
    margin-left: 8px;
}
.extraBox {
    width: 180px;
    background: white;
    border: 2px solid #999999;
    top: -55px;
    left: 380px;
    margin-bottom: -92px;
    /*margin-top: -80px;
    margin-left: 1000px;*/
    position: relative;
    display: block;
}
.extraBox1 {
    font-family: 'Open Sans', sans-serif;
    font-size: 25px;
    color: #47BC47;
    background: white;
    margin: 5px;
    margin-bottom: 10px;
}
.extraBox1:hover {
    cursor: pointer;
    background: #47BC47;
    color: white;
}
.extraBox2:hover {
    cursor: pointer;
    background: #D41B1B;
    color: white;
}
.extraBox2 {
    font-family: 'Open Sans', sans-serif;
    font-size: 25px;
    color: #D41B1B;
    background: white;
    margin: 5px;
    margin-top: 0px;
}
#programButtonText {
    line-height: 65px;
}
.hoverText {
    cursor: pointer;
}
.lastVisited {
    font-family: 'Open Sans', sans-serif;
    font-size: 22px;
    margin-top: -35px;
    margin-left: -793px;
}
.entireProgramButton {
    display: block;
    cursor: default;
}
.programButtonExtra {
    margin-top: -41px;
    margin-left: 980px;
}
span.tooltips {
  position: relative;
  display: inline;
}
span.tooltips span {
  font-family: 'Open Sans', sans-serif;
  font-size: 22px;
  position: absolute;
  color: #FFFFFF;
  background: #000000;
  height: 40px;
  line-height: 40px;
  text-align: center;
  display: none;
  visibility: hidden;
  border-radius: 9px;
}
span.tooltips span:after {
  content: '';
  position: absolute;
  top: 100%;
  left: 50%;
  width: 0; height: 0;
  border-top: 8px solid #000000;
  border-right: 8px solid transparent;
  border-left: 8px solid transparent;
}
span:hover.tooltips span {
  visibility: visible;
  display: block;
  opacity: 1;
  bottom: 30px;
  right: -378px;
  top: -35px;
  margin-left: -76px;
}

因此，正如您所看到的(在整个页面的结果上最好的结果)，当您悬停在i上时，它显示了一个关于它的小工具提示。这是可行的，但您会注意到，文本的两边都有很多空白。这是因为当我制作它的时候，800px of width在工具提示上工作。既然我有30个工具提示，我怎么能得到它，使它的宽度大约延伸到适合文本？

编辑：--在这个特定的框中，如果去掉宽度，工具提示看起来并不坏(除了移动)。我用我本来想要的另一个程序代替了这个程序。

我也拿出宽度来告诉你没有它会发生什么。

Answer 1

把span.tooltips span的宽度取出来。跨度将调整到内容。我还添加了一些右和左填充到那个类，使它看起来更整洁。
