我开发了三种类型的褪色效果:

/* setup tooltips */ .tooltip { position: relative; } .tooltip:before, .tooltip:after { display: block; opacity: 0; pointer-events: none; position: absolute; } .tooltip:after { border-right: 6px solid transparent; border-bottom: 6px solid rgba(0,0,0,.75); border-left: 6px solid transparent; content: ''; height: 0; top: 20px; left: 20px; width: 0; } .tooltip:before { background: rgba(0,0,0,.75); border-radius: 2px; color: #fff; content: attr(data-title); font-size: 14px; padding: 6px 10px; top: 26px; white-space: nowrap; } /* the animations */ /* fade */ .tooltip.fade:after, .tooltip.fade:before { transform: translate3d(0,-10px,0); transition: all .15s ease-in-out; } .tooltip.fade:hover:after, .tooltip.fade:hover:before { opacity: 1; transform: translate3d(0,0,0); } /* expand */ .tooltip.expand:before { transform: scale3d(.2,.2,1); transition: all .2s ease-in-out; } .tooltip.expand:after { transform: translate3d(0,6px,0); transition: all .1s ease-in-out; } .tooltip.expand:hover:before, .tooltip.expand:hover:after { opacity: 1; transform: scale3d(1,1,1); } .tooltip.expand:hover:after { transition: all .2s .1s ease-in-out; } /* swing */ .tooltip.swing:before, .tooltip.swing:after { transform: translate3d(0,30px,0) rotate3d(0,0,1,60deg); transform-origin: 0 0; transition: transform .15s ease-in-out, opacity .2s; } .tooltip.swing:after { transform: translate3d(0,60px,0); transition: transform .15s ease-in-out, opacity .2s; } .tooltip.swing:hover:before, .tooltip.swing:hover:after { opacity: 1; transform: translate3d(0,0,0) rotate3d(1,1,1,0deg); } /* basic styling: has nothing to do with tooltips: */ h1 { padding-left: 50px; } ul { margin-bottom: 40px; } li { cursor: pointer; display: inline-block; padding: 0 10px; } <h1>FADE</h1> <div class="tooltip fade" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div> <h1>EXPAND</h1> <div class="tooltip expand" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div> <h1>SWING</h1> <div class="tooltip swing" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div>

你可以使用纯CSS制作工具提示。试试这个。希望能帮助你解决你的问题。

HTML

<div class="tooltip"> Name
    <span class="tooltiptext">Add your tooltip text here.</span>
</div>

CSS

.tooltip {
        position: relative;
        display: inline-block;
        cursor: pointer;
    }

    .tooltip .tooltiptext {
        visibility: hidden;
        width: 270px;
        background-color: #555;
        color: #fff;
        text-align: center;
        border-radius: 6px;
        padding: 5px 0;
        position: absolute;
        z-index: 1;
        bottom: 125%;
        left: 50%;
        margin-left: -60px;
        opacity: 0;
        transition: opacity 1s;
    }

    .tooltip .tooltiptext::after {
        content: "";
        position: absolute;
        top: 100%;
        left: 50%;
        margin-left: -5px;
        border-width: 5px;
        border-style: solid;
        border-color: #555 transparent transparent transparent;
    }

    .tooltip:hover .tooltiptext {
        visibility: visible;
        opacity: 1;
    }

我为它创造了一个公式。 首先是html

<div class="tooltip-container">
  <button class="tooltip-tarjet">
    My Button
  </button>
  <div class="tooltip-element"> 
    This is my tooltip content right here...
  </div>
</div>

现在是它的css

.tooltip-container { 
  /* it contains the tooltip message and the one firing the tooltip
   * it has position relative since it allows for a better responsive positioning
   * of the tooltip-element */
  display: inline-block;
  position: relative;
  flex-direction: row;
}
.tooltip-tarjet:hover + .tooltip-element {
  /* this selector rule matches the tooltip-element right after
   * tooltip-tarjet at a hover action
   *  */
  display: inline-block;
  position: absolute;
  background-color: #869096;
  color: white;
  opacity: 1;
  transition: all 1s;
}
.tooltip-element { 
  /* here goes the tooltip-element styles and positioning, now your
   * tooltip element will always remain to your desired positionno matter
   * the screen size at hand 
   *  */ 
  display: none; 
  opacity: 0;
  text-align: center;
  padding: 7px;
  z-index: 10;
  width: 200px;
  left: -60px;
  bottom: 48px;
  border-radius: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  font-size: 12px;
  line-height: 1.5;
}

对于基本的工具提示，您需要:

<div title="This is my tooltip">

如:

.visible { 高度:3他们; 宽度:10 em; 背景:黄色; } <div title="This is my tooltip" class="visible"></div> .

对于一个更花哨的javascript版本，你可以查看:

上面的链接提供了25个工具提示选项。

好了，这是你满足的所有赏金要求:

没有jQuery 即时出现 直到老鼠离开这个区域才会消失 淡入/淡出效果纳入 最后. .简单的解决方案

下面是一个演示和我的代码链接(JSFiddle)

以下是我在这款纯JS、CSS和HTML5游戏中加入的功能:

你可以设置淡出的速度。 您可以使用一个简单的变量来设置工具提示的文本。

HTML:

<div id="wrapper">
    <div id="a">Hover over this div to see a cool tool tip!</div>
</div>

CSS:

#a{
    background-color:yellow;
    padding:10px;
    border:2px solid red;    
}

.tooltip{
    background:black;
    color:white;
    padding:5px;
    box-shadow:0 0 10px 0 rgba(0, 0, 0, 1);
    border-radius:10px;
    opacity:0;
}

JavaScript:

var div = document.getElementById('wrapper');
var a = document.getElementById("a");
var fadeSpeed = 25; // a value between 1 and 1000 where 1000 will take 10
                    // seconds to fade in and out and 1 will take 0.01 sec.
var tipMessage = "The content of the tooltip...";

var showTip = function(){    
    var tip = document.createElement("span");
    tip.className = "tooltip";
    tip.id = "tip";
    tip.innerHTML = tipMessage;
    div.appendChild(tip);
    tip.style.opacity="0"; // to start with...
    var intId = setInterval(function(){
        newOpacity = parseFloat(tip.style.opacity)+0.1;
        tip.style.opacity = newOpacity.toString();
        if(tip.style.opacity == "1"){
            clearInterval(intId);
        }
    }, fadeSpeed);
};
var hideTip = function(){
    var tip = document.getElementById("tip");
    var intId = setInterval(function(){
        newOpacity = parseFloat(tip.style.opacity)-0.1;
        tip.style.opacity = newOpacity.toString();
        if(tip.style.opacity == "0"){
            clearInterval(intId);
            tip.remove();
        }
    }, fadeSpeed);
    tip.remove();
};

a.addEventListener("mouseover", showTip, false);
a.addEventListener("mouseout", hideTip, false);

你也可以使用这个作为工具提示…它的工作原理是一样的，但你必须写额外的标签。

<abbr title="THis is tooltip"></abbr>
