Question

我想要查看黑色标题框而不是像<i class = "fa fa-eye" title = "Something"></i>这样的常规标题框，我认为现在已经有了现成的HTML标签，因为我已经在其他地方看到了但根本无法记住！如果你知道这个标签，请帮助我。

在共享按钮上方，您可以看到一个标题为“共享”的黑匣子。我想看看！

Answer 1

这些是Bootstrap工具提示。您可以在此处找到文档：Bootstrap Tooltips。

如果你包含Bootstrap库，你可以轻松修改和编辑工具提示等等。

w3schools有@Ihaz提到的那个。 Link

void func(set<int*>& s1, set<int*>& s2, int& a)
{
    s1.insert(&a);
    s2.insert(&a);
}

.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black;
}

.tooltip .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: black;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  z-index: 1;
  bottom: 150%;
  left: 50%;
  margin-left: -60px;
}

.tooltip .tooltiptext::after {
  content: "";
  position: absolute;
  top: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: black transparent transparent transparent;
}

.tooltip:hover .tooltiptext {
  visibility: visible;
}

如果需要，可以创作一个;

<body style="text-align:center;">
  <h2>Top Tooltip w/ Bottom Arrow</h2>

  <div class="tooltip">Hover over me
    <span class="tooltiptext">Tooltip text</span>
  </div>
</body>

.wrapper {
  text-transform: uppercase;
  background: #ececec;
  color: #555;
  cursor: help;
  font-family: "Gill Sans", Impact, sans-serif;
  font-size: 20px;
  margin: 100px 75px 10px 75px;
  padding: 15px 20px;
  position: relative;
  text-align: center;
  width: 200px;
  -webkit-transform: translateZ(0);
  /* webkit flicker fix */

  /* webkit text rendering fix */
}

.wrapper .tooltip {
  background: #e84747;
  bottom: 100%;
  color: #fff;
  display: block;
  left: -20px;
  margin-bottom: 15px;
  opacity: 0;
  padding: 20px;
  pointer-events: none;

  -webkit-transform: translateY(10px);
  -moz-transform: translateY(10px);

  -o-transform: translateY(10px);
  transform: translateY(10px);
  -webkit-transition: all .25s ease-out;
  -moz-transition: all .25s ease-out;
  -ms-transition: all .25s ease-out;
  -o-transition: all .25s ease-out;

  box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
}


/* This bridges the gap so you can mouse into the tooltip without it disappearing */

.wrapper .tooltip:before {
  bottom: -20px;
  content: " ";
  display: block;
  height: 20px;
  left: 0;
  position: absolute;
  width: 100%;
}

.wrapper .tooltip:after {
  border-left: solid transparent 10px;
  border-right: solid transparent 10px;
  border-top: solid #e84747 10px;
  bottom: -10px;
  content: " ";
  height: 0;
  left: 50%;
  margin-left: -13px;
  position: absolute;
  width: 0;
}

.wrapper:hover .tooltip {
  opacity: 1;
  pointer-events: auto;
  -webkit-transform: translateY(0px);
  -moz-transform: translateY(0px);
  -ms-transform: translateY(0px);
  -o-transform: translateY(0px);
  transform: translateY(0px);
}


/* IE can just show/hide with no transition */

.lte8 .wrapper .tooltip {
  display: none;
}

.lte8 .wrapper:hover .tooltip {
  display: block;
}
