当您将鼠标悬停在网页的某个区域上时,有很多基于JavaScript的库会显示工具提示。有些是相当简单的,有些允许工具提示显示用CSS设置样式的HTML内容。
但有没有办法在不使用JavaScript的情况下显示样式化的工具提示?如果您只使用title
属性,则不会处理代码(例如foo<br />bar
不会产生换行符)。我正在寻找一种解决方案,允许用户在不使用任何JavaScript的情况下显示样式化的HTML内容。

我使用css
.hover {
position: relative;
top: 50px;
left: 50px;
}
.tooltip {
/* hide and position tooltip */
top: -10px;
background-color: black;
color: white;
border-radius: 5px;
opacity: 0;
position: absolute;
-webkit-transition: opacity 0.5s;
-moz-transition: opacity 0.5s;
-ms-transition: opacity 0.5s;
-o-transition: opacity 0.5s;
transition: opacity 0.5s;
}
.hover:hover .tooltip {
/* display tooltip on hover */
opacity: 1;
}
<div class="hover">hover
<div class="tooltip">asdadasd
</div>
</div>

与koningdavid相似,但适用于display:none和block,并添加其他样式。
div.tooltip {
position: relative;
/* DO NOT include below two lines, as they were added so that the text that
is hovered over is offset from top of page*/
top: 10em;
left: 10em;
/* if want hover over icon instead of text based, uncomment below */
/* background-image: url("../images/info_tooltip.svg");
/!* width and height of svg *!/
width: 16px;
height: 16px;*/
}
/* hide tooltip */
div.tooltip span {
display: none;
}
/* show and style tooltip */
div.tooltip:hover span {
/* show tooltip */
display: block;
/* position relative to container div.tooltip */
position: absolute;
bottom: 1em;
/* prettify */
padding: 0.5em;
color: #000000;
background: #ebf4fb;
border: 0.1em solid #b7ddf2;
/* round the corners */
border-radius: 0.5em;
/* prevent too wide tooltip */
max-width: 10em;
}
&#13;
<div class="tooltip">
hover_over_me
<span>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec quis purus dui. Sed at orci. </span>
</div>

您可以使用title属性,例如如果你想对文本进行工具提示,只需制作:
<span title="This is a Tooltip">This is a text</span>

用css做另一种类似的方法:
<style>
#img { }
#img:hover {visibility:hidden}
#thistext {font-size:22px;color:white }
#thistext:hover {color:black;}
#hoverme {width:50px;height:50px;
}
#hoverme:hover { background-color:green;position:absolute ;left:300px;top:100px;width:40%;height:20%;}
</style>
<p id="hoverme"><img id="img" src="http://a.deviantart.net/avatars/l/o/lol-cat.jpg"></img><span id="thistext">LOCATZ!!!!</span></p>

这是我的解决方案:
https://gist.github.com/BryanMoslo/808f7acb1dafcd049a1aebbeef8c2755
该元素使用工具提示文本替换为“工具提示标题”属性,并且在悬停时随CSS一起显示,我更喜欢此解决方案,因为我不必将工具提示文本作为HTML元素包含!
