html - 如何使工具提示拉伸(stretch)以适合文本(没有预定义的宽度)

Question

所以，我有一个工具提示，我希望它可以拉伸(stretch)以适合其中的所有文本。我实际上有大约 30 个工具提示，我不想手动更改它们(我试过了但没有用，所以我不确定我会怎么做)。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;
}

    <div id = "entireProgramButton9" class = "entireProgramButton">
        <div id = "programButton9" class = "programButton"><div id = "programButtonText"><span id = "programName9" class = "hoverText">Tic-Tac-Toe&nbsp;<span class = "tooltips" id = "information">ⓘ<span>The Tic-Tac-Toe game lets you play against AI or another player.</span></span></span></div><div class = "programButtonExtra" id = "programButtonExtra9"><span class = "hoverText">⋮</span></div></div>
        <div class = "lastVisited">Last visited: Never</div>
        <div class = "extraBox" id = "extraBox9">
            <div id = "extraBox19" class = "extraBox1">Save for later</div>
            <div id = "extraBox29" class = "extraBox2">Report a bug</div>
        </div>
    </div>
</center>

因此，如您所见(整页结果中的最佳结果)，当您将鼠标悬停在 ⓘ 上时，它会显示一个小工具提示，告诉您相关信息。这行得通，但您会注意到文本两边有很多空白区域。这是因为当我制作它时，width 的 800px 在工具提示上起作用。由于我有大约 30 个工具提示，我怎样才能让它的宽度大约拉伸(stretch)以适合文本？

编辑:事实证明，在这个特定的框上，如果去掉宽度，工具提示看起来还不错(除了移动之外)。我用另一个我想要的程序替换了该程序。

我还拿出了宽度来告诉你没有它会发生什么。

只需从 span.tooltips span 中取出宽度。跨度将根据内容调整大小。我还向该类添加了一些左右填充，使其看起来更整洁。
