我有一个这样的div标签:
<div>
<label>Name</label>
<input type="text"/>
</div>
我如何显示一个工具提示:div的悬停,最好有一个淡入/淡出效果。

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;
}

最简单的方法是在包含元素上设置position: relative,在容器内的工具提示元素上设置position: absolute,使其相对于父元素(包含元素)浮动。例如:
<div style="background: yellow;">
<div style="display: inline-block; position: relative; background: pink;">
<label>Name</label>
<input type="text" />
<div style="background: #e5e5e5; position: absolute; top: -10px; left: 0; right: 0;">
Tooltip text
</div>
</div>
</div>
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。
http://jsfiddle.net/clintioo/gLeydk0k/11/
<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>
仅css3的解决方案可以是:
CSS3:
div[id^="tooltip"]:after {content: attr(data-title); background: #e5e5e5; position: absolute; top: -10px; left: 0; right: 0; z-index: 1000;}
HTML5:
<div style="background: yellow;">
<div id="tooltip-1" data-title="Tooltip Text" style="display: inline-block; position: relative; background: pink;">
<label>Name</label>
<input type="text" />
</div>
</div>
然后你可以用同样的方法创建一个tooltip-2 div…当然,您也可以使用title属性而不是data属性。
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);
