如何在不悬停的情况下默认显示工具提示 css

Question

我有下面的工具提示，当我们将鼠标悬停在 div 元素

上时，它会起作用

我需要在刷新页面时默认显示工具提示。

如何在纯 css 中实现它？我这里不需要任何 javascript 东西。有没有让它只与 css 一起工作的想法？

我尝试从 tooltip:before 中删除 display: block;，但其中 none 有效。

.toolwrapper {
  color: #555;
  cursor: help;
  font-family: Arial;
  font-size: 12px;
  margin: 40px 64px 9px 4px;
  padding: 15px 20px;
  position: relative;
  text-align: center;
  width: 100%;

}

.toolwrapper .tooltip {
  background: #424242;
  bottom: 100%;
  color: #fff;
  display: block;
  left: 0;
  opacity: 0;
  padding: 10px;
  pointer-events: none;
  position: absolute;
  width: 100%;
  -webkit-transform: translateY(10px);
     -moz-transform: translateY(10px);
      -ms-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;
          transition: all .25s ease-out;
  -webkit-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
     -moz-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
      -ms-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
       -o-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
          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 */
.toolwrapper .tooltip:before {
  bottom: -20px;
  content: " ";
  display: block;
  height: 20px;
  left: 0;
  position: absolute;
  width: 100%;
}  


.toolwrapper .tooltip:after {
  border-left: solid transparent 10px;
  border-right: solid transparent 10px;
  border-top: solid #424242 10px;
  bottom: -10px;
  content: " ";
  height: 0;
  left: 80%;
  margin-left: -13px;
  position: absolute;
  width: 0;
}
  
.toolwrapper: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);
}

<div class="toolwrapper">
               Hover me to show tooltip
              <div class="tooltip">Hi I'm tooltip</div>
            </div>

Answer 1

您只需在工具提示 class 上将 opacity 从 0 更改为 1，因为将其设置为 0 会使其不可见。

.toolwrapper .tooltip {
    opacity: 1;
}

Answer 2

在工具提示中添加opacity: 1

.toolwrapper {
  color: #555;
  cursor: help;
  font-family: Arial;
  font-size: 12px;
  margin: 40px 64px 9px 4px;
  padding: 15px 20px;
  position: relative;
  text-align: center;
  width: 100%;

}

.toolwrapper .tooltip {
  background: #424242;
  bottom: 100%;
  color: #fff;
  display: block;
  left: 0;
  opacity: 1 !important;
  padding: 10px;
  pointer-events: none;
  position: absolute;
  width: 100%;
  -webkit-transform: translateY(0px);
     -moz-transform: translateY(0px);
      -ms-transform: translateY(0px);
       -o-transform: translateY(0px);
          transform: translateY(0px);
  -webkit-transition: all .25s ease-out;
     -moz-transition: all .25s ease-out;
      -ms-transition: all .25s ease-out;
       -o-transition: all .25s ease-out;
          transition: all .25s ease-out;
  -webkit-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
     -moz-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
      -ms-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
       -o-box-shadow: 2px 2px 6px rgba(0, 0, 0, 0.28);
          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 */
.toolwrapper .tooltip:before {
  bottom: -20px;
  content: " ";
  display: block;
  height: 20px;
  left: 0;
  position: absolute;
  width: 100%;
}  


.toolwrapper .tooltip:after {
  border-left: solid transparent 10px;
  border-right: solid transparent 10px;
  border-top: solid #424242 10px;
  bottom: -10px;
  content: " ";
  height: 0;
  left: 80%;
  margin-left: -13px;
  position: absolute;
  width: 0;
}
  
.toolwrapper: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);
}

<div class="toolwrapper">
   Hover me to show tooltip
  <div class="tooltip">Hi I'm tooltip</div>
</div>
