您可以使用数据属性，伪元素和内容创建自定义CSS工具提示:attr()等。

<div data-tooltip="This is my tooltip">
    <label>Name</label>
    <input type="text" />
</div>

.

div:hover:before {
    content: attr(data-tooltip);
    position: absolute;
    padding: 5px 10px;
    margin: -3px 0 0 180px;
    background: orange;
    color: white;
    border-radius: 3px;
}

div:hover:after {
    content: '';
    position: absolute;
    margin: 6px 0 0 3px;
    width: 0;
    height: 0;
    border-top: 5px solid transparent;
    border-right: 10px solid orange;
    border-bottom: 5px solid transparent;
}

input[type="text"] {
    width: 125px;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}

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>

我做了一些事情，应该能够适应一个div以及。

HTML

<td>
    <%# (Eval("Name").ToString().Length > 65) ? Eval("Name").ToString().Substring(0, 60) + "..." : Eval("Name")%>
    <span class="showonhover">
        <a href="#"><%# (Eval("Name").ToString().Length > 65) ? "More" : "" %></a>
        <span class="hovertext">
            <%# Eval("Name") %>
        </span>
    </span>
</td>

CSS

.showonhover .hovertext { display: none;}
.showonhover:hover .hovertext {display: inline;}
a.viewdescription {color:#999;}
a.viewdescription:hover {background-color:#999; color: White;}
.hovertext {position:absolute;z-index:1000;border:1px solid #ffd971;background-color:#fffdce;padding:11px;width:150px;font-size: 0.75em;}

要了解更深入的讨论，请参阅我的文章:

一个简单的格式化工具提示文本悬停

您可以尝试引导工具提示。

$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})

进一步阅读

这是一个纯css3实现(可选JS)

你要做的唯一一件事就是在任何div上设置一个名为“data-tooltip”的属性，当你将鼠标悬停在它上面时，该文本将显示在它旁边。

我已经包含了一些可选的JavaScript，可以使工具提示显示在光标附近。如果您不需要这个特性，您可以放心地忽略这个小提琴的JavaScript部分。

如果您不希望在悬停状态上淡入，只需删除过渡属性。

它的样式类似于title属性工具提示。这是JSFiddle: http://jsfiddle.net/toe0hcyn/1/

HTML的例子:

<div data-tooltip="your tooltip message"></div>

CSS:

*[data-tooltip] {
    position: relative;
}

*[data-tooltip]::after {
    content: attr(data-tooltip);

    position: absolute;
    top: -20px;
    right: -20px;
    width: 150px;

    pointer-events: none;
    opacity: 0;
    -webkit-transition: opacity .15s ease-in-out;
    -moz-transition: opacity .15s ease-in-out;
    -ms-transition: opacity .15s ease-in-out;
    -o-transition: opacity .15s ease-in-out;
    transition: opacity .15s ease-in-out;

    display: block;
    font-size: 12px;
    line-height: 16px;
    background: #fefdcd;
    padding: 2px 2px;
    border: 1px solid #c0c0c0;
    box-shadow: 2px 4px 5px rgba(0, 0, 0, 0.4);
}

*[data-tooltip]:hover::after {
    opacity: 1;
}

基于鼠标位置的工具提示位置更改的可选JavaScript:

var style = document.createElement('style');
document.head.appendChild(style);

var matchingElements = [];
var allElements = document.getElementsByTagName('*');
for (var i = 0, n = allElements.length; i < n; i++) {
    var attr = allElements[i].getAttribute('data-tooltip');
    if (attr) {
        allElements[i].addEventListener('mouseover', hoverEvent);
    }
}

function hoverEvent(event) {
    event.preventDefault();
    x = event.x - this.offsetLeft;
    y = event.y - this.offsetTop;

    // Make it hang below the cursor a bit.
    y += 10;

    style.innerHTML = '*[data-tooltip]::after { left: ' + x + 'px; top: ' + y + 'px  }'

}

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。
