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。
你根本不需要JavaScript;只需设置title属性:
<div title="Hello, World!">
<label>Name</label>
<input type="text"/>
</div>
请注意,工具提示的可视化表示依赖于浏览器/操作系统,因此它可能会逐渐消失,也可能不会。然而,这是实现工具提示的语义方式,它可以正确地与屏幕阅读器等辅助软件一起工作。
在堆栈片段中的演示
<div title="Hello, World!"> < >标签名称> < /标签 < input type = " text " / > < / div >
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:
https://jqueryhouse.com/best-jquery-tooltip-plugins/
上面的链接提供了25个工具提示选项。
这是一个漂亮的jQuery工具提示:
https://jqueryui.com/tooltip/
要实现这一点,只需遵循以下步骤:
Add this code in your <head></head> tags: <script type="text/javascript" src="http://cdn.jquerytools.org/1.2.5/full/jquery.tools.min.js"></script> <script type="text/javascript"> $("[title]").tooltip(); </script> <style type="text/css"> /* tooltip styling. by default the element to be styled is .tooltip */ .tooltip { display:none; background:transparent url(https://dl.dropboxusercontent.com/u/25819920/tooltip/black_arrow.png); font-size:12px; height:70px; width:160px; padding:25px; color:#fff; } </style> On the HTML elements that you want to have the tooltip, just add a title attribute to it. Whatever text is in the title attribute will be in the tooltip.
注意:当JavaScript被禁用时,它将回退到默认的浏览器/操作系统工具提示。
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
<!doctype html>
<html lang="en">

$(function() {
$("#tooltip").tooltip();
});
</script>
</head>
<body>
<div id="tooltip" title="I am tooltip">mouse over me</div>
</body>
</html>
您还可以自定义工具提示样式。请参阅此连结: http://jqueryui.com/tooltip/#custom-style
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;
}
你可以像这样在onmouseover和onmouseout期间切换子div:
function Tooltip(el, text) {
el.onmouseover = function() {
el.innerHTML += '<div class="tooltip">' + text + '</div>'
}
el.onmouseout = function() {
el.removeChild(el.querySelector(".tooltip"))
}
}
//Sample Usage
Tooltip(document.getElementById("mydiv"),"hello im a tip div")
Stack Snippets & jsFiddle中的例子
function Tooltip(el, text) { el.onmouseover = function() { el.innerHTML += '<div class="tooltip">' + text + '</div>' } el.onmouseout = function() { el.removeChild(el.querySelector(".tooltip")) } } //Sample Usage Tooltip(document.getElementById("mydiv"), "I'm a tooltip") #mydiv { position: relative; display: flex; align-items: center; justify-content: center; width: 120px; height: 50px; padding: 5px 10px; background-color: #e2f7ff; box-shadow: 1px 1px 1px 0px #cecece; } .tooltip { position: absolute; display: inline-block; white-space: nowrap; width: auto; height: auto; background-color: #11121b; color: white; padding: 4px 6px; border-radius: 3px; z-index: 99; left: 100%; top: 0; } <div id="mydiv"> This is just a div </div>
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>
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。
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 }'
}
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);
它可以只用CSS,不需要javascript
运行演示
[data-tooltip]:before { /* needed - do not touch */ content: attr(data-tooltip); position: absolute; opacity: 0; /* customizable */ transition: all 0.15s ease; padding: 10px; color: #333; border-radius: 10px; box-shadow: 2px 2px 1px silver; } [data-tooltip]:hover:before { /* needed - do not touch */ opacity: 1; /* customizable */ background: yellow; margin-top: -50px; margin-left: 20px; } [data-tooltip]:not([data-tooltip-persistent]):before { pointer-events: none; } /* FOR TEST PURPOSES ONLY */ div { border: 1px solid silver; background: #ddd; margin: 20px; padding: 10px; } <div>Standard div, no tooltip here</div> <div data-tooltip="Hi, I'm a tooltip. Pretty easy uh ? ;)">Div with standard tooltip. Hover me to see the tooltip. <br/>Hovering the tooltip doesn't matter: <br/>if you hover out of my boundaries, the tooltip will disappear.</div> <div data-tooltip="Hi, I'm a persistent tooltip. I won't disappear when hovering me even if out of my parent boundaries. I'll also prevent other tooltips to fire :)" data-tooltip-persistent="foo">Div with persistent tooltip. Hover me to see the tooltip. <br/>The tooltip won't expire until you hover on me OR it.</div>
Apply a custom HTML attribute, eg. data-tooltip="bla bla" to your object (div or whatever): <div data-tooltip="bla bla"> something here </div> Define the :before pseudoelement of each [data-tooltip] object to be transparent, absolutely positioned and with data-tooltip="" value as content: [data-tooltip]:before { position : absolute; content : attr(data-tooltip); opacity : 0; } Define :hover:before hovering state of each [data-tooltip] to make it visible: [data-tooltip]:hover:before { opacity : 1; } Apply your styles (color, size, position etc) to the tooltip object; end of the story.
在演示中,我定义了另一个规则来指定当鼠标悬停在工具提示上但不在父工具提示上时,工具提示是否必须消失,使用另一个自定义属性data-tooltip-persistent和一个简单的规则:
[data-tooltip]:not([data-tooltip-persistent]):before {
pointer-events: none;
}
注1:浏览器的覆盖范围很广,但可以考虑为旧的IE使用javascript回退(如果需要的话)。
注2:一种增强可能是添加一些javascript来计算鼠标位置,并通过改变应用于它的类将其添加到伪元素中。
不使用任何API 你也可以通过使用纯CSS和Jquery演示来做这样的事情
HTML
<div class="pointer_tooltip">
Click & Drag to draw the area
</div>
CSS
.pointer_tooltip{
width : auto;
height : auto;
padding : 10px;
border-radius : 5px;
background-color : #fff;
position: absolute;
}
Jquery
$(document).mousemove(function( event ) {
var pageCoords = "( " + event.pageX + ", " + event.pageY + " )";
//set the actuall width
$('.pointer_tooltip').width($('.pointer_tooltip').width());
var position_top = event.pageY+18;
var position_left = event.pageX-60;
var width=$('body').width()-$('.pointer_tooltip').width();
//check if left not minus
if(position_left<0){
position_left=10;
}else if(position_left > width){
position_left=width-10;
}
$('.pointer_tooltip').css('top',position_top+'px');
$('.pointer_tooltip').css('left',position_left+'px');
});
你可以用title。它几乎适用于所有事情
<div title="非常适合通过合作结交新朋友。">
<input script=JavaScript type=button title="Click for a compliment" onclick="窗口。alert(“你的头发让我想起了草原上的日落”)”value=“让你快乐”>
<table title="为理解我感受的人工作真是太棒了">
只要想到任何可以在HTML窗口中可见的标签,并在标签中插入title=“whatever tooltip you'd like”,你就得到了一个工具提示。
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;
}
这个问题有很多答案,但它仍然可能会帮助到一些人。它适用于所有左、右、上、下位置。
下面是css:
.m-tb-5 {
margin-top: 2px;
margin-bottom: 2px;
}
[data-tooltip] {
display: inline-block;
position: relative;
cursor: help;
padding: 3px;
}
/* Tooltip styling */
[data-tooltip]:before {

line-height: 1.4;
min-width: 100px;
text-align: center;
border-radius: 4px;
}
/* Dynamic horizontal centering */
[data-tooltip-position="top"]:before,
[data-tooltip-position="bottom"]:before {
left: 50%;
-ms-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
}
/* Dynamic vertical centering */
[data-tooltip-position="right"]:before,
[data-tooltip-position="left"]:before {

margin-bottom: 6px;
}
[data-tooltip-position="right"]:before {
left: 100%;
margin-left: 6px;
}
[data-tooltip-position="bottom"]:before {
top: 100%;
margin-top: 6px;
}
[data-tooltip-position="left"]:before {
right: 100%;
margin-right: 6px;
}
/* Tooltip arrow styling/placement */
[data-tooltip]:after {
content: '';
display: none;
position: absolute;
width: 0;
height: 0;
border-color: transparent;
border-style: solid;
}
/* Dynamic horizontal centering for the tooltip */
[data-tooltip-position="top"]:after,
[data-tooltip-position="bottom"]:after {
left: 50%;
margin-left: -6px;
}
/* Dynamic vertical centering for the tooltip */
[data-tooltip-position="right"]:after,
[data-tooltip-position="left"]:after {
top: 50%;
margin-top: -6px;
}
[data-tooltip-position="top"]:after {
bottom: 100%;
border-width: 6px 6px 0;
border-top-color: #000;
}
[data-tooltip-position="right"]:after {

border-width: 6px 6px 6px 0;
border-right-color: #000;
}
[data-tooltip-position="left"]:after {

border-width: 6px 0 6px 6px;
border-left-color: #000;
}
/* Show the tooltip when hovering */
[data-tooltip]:hover:before,
[data-tooltip]:hover:after {
display: block;
z-index: 50;
}
HTML标签可以是这样的:
<p data-tooltip-position="right" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="left" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="top" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="bottom" data-tooltip="Some tooltip text here" title=" > text here </p> .
工具提示定位纯css
div { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); -ms-transform: translate(-50%, -50%); /* IE 9 */ -webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */ text-align: center; } .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 the tooltip */ position: absolute; z-index: 1; } .tooltip:hover .tooltiptext { visibility: visible; } .toolLeft { top: -5px; right: 105%; } .toolRight { top: -5px; left: 105%; } .toolTop { bottom: 100%; left: 50%; margin-left: -60px; } .toolBottom { top: 100%; left: 50%; margin-left: -60px; } <div> <div class="tooltip">Top <span class="tooltiptext toolTop">Tooltip text</span></div><br /> <div class="tooltip">Left <span class="tooltiptext toolLeft">Tooltip text</span></div><br /> <div class="tooltip">Right <span class="tooltiptext toolRight">Tooltip text</span></div><br /> <div class="tooltip">Bottom <span class="tooltiptext toolBottom">Tooltip text</span></div><br /> </div>
我的版本是
.tooltip{
display: inline;
position: relative; /** very important set to relative*/
}
.tooltip:hover:after{
background: #333;
background: rgba(0,0,0,.8);
border-radius: 5px;
bottom: 26px;
color: #fff;
content: attr(title); /**extract the content from the title */
left: 20%;
padding: 5px 15px;
position: absolute;
z-index: 98;
width: 220px;
}
.tooltip:hover:before{
border: solid;
border-color: #333 transparent;
border-width: 6px 6px 0 6px;
bottom: 20px;
content: "";
left: 50%;
position: absolute;
z-index: 99;
}
然后是HTML
<div title="This is some information for our tooltip." class="tooltip">bar </div>
你可以用简单的css…Jsfiddle这里你可以看到这个例子
下面是工具提示的CSS代码
[data-tooltip] {
position: relative;
z-index: 2;
cursor: pointer;
}
/* Hide the tooltip content by default */
[data-tooltip]:before,
[data-tooltip]:after {
visibility: hidden;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=0);
opacity: 0;
pointer-events: none;
}
/* Position tooltip above the element */
[data-tooltip]:before {
position: absolute;
bottom: 150%;
left: 50%;
margin-bottom: 5px;
margin-left: -80px;
padding: 7px;
width: 160px;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
background-color: #000;
background-color: hsla(0, 0%, 20%, 0.9);
color: #fff;
content: attr(data-tooltip);
text-align: center;
font-size: 14px;
line-height: 1.2;
}
/* Triangle hack to make tooltip look like a speech bubble */
[data-tooltip]:after {
position: absolute;
bottom: 150%;
left: 50%;
margin-left: -5px;
width: 0;
border-top: 5px solid #000;
border-top: 5px solid hsla(0, 0%, 20%, 0.9);
border-right: 5px solid transparent;
border-left: 5px solid transparent;
content: " ";
font-size: 0;
line-height: 0;
}
/* Show tooltip content on hover */
[data-tooltip]:hover:before,
[data-tooltip]:hover:after {
visibility: visible;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=100);
opacity: 1;
}
试试这个。你可以这样做,只有css和我只添加了数据标题属性的工具提示。
.tooltip { 位置:相对; 显示:inline-block; } .tooltip [data-title]:徘徊:{后 内容:attr (data-title); 填充:4px 8px; 颜色:# fff; 位置:绝对的; 左:0; 上图:110%; 空白:nowrap;} border - radius: 5 px; 背景:# 000; } <div data-title="My tooltip" class="tooltip"> < >标签名称> < /标签 < input type = " text " / > < / div >
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>
下面是一个简单的工具提示实现,它可以考虑鼠标的位置以及窗口的高度和宽度:

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;
}
