Tooltip with HTML content without JavaScript

问题:

There are plenty of JavaScript-based libraries that show tooltips when you hover your mouse over a certain area of a web page. Some are rather plain, some allow the tooltip to display HTML content styled with CSS.

But is there a way to show a styled tooltip without using JavaScript? If you just use the title attribute, tags are not processed (e.g. foo<br />bar doesn't produce a line break). I'm looking for a solution that allows one to display styled HTML content without using any JavaScript.

I have made a little example using 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>

Using the title attribute:

<a href="#" title="Tooltip here">Link</a>

Similar to koningdavid's, but works on display:none and block, and adds additional styling.

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;
}

<div class="tooltip">
  hover_over_me
  <span>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec quis purus dui. Sed at orci. </span>
</div>

This one is very interesting,

HTML and CSS only

.help-tip {
  position: absolute;
  top: 18px;
  left: 18px;
  text-align: center;
  background-color: #BCDBEA;
  border-radius: 50%;
  width: 24px;
  height: 24px;
  font-size: 14px;
  line-height: 26px;
  cursor: default;
}

.help-tip:before {
  content: '?';
  font-weight: bold;
  color: #fff;
}

.help-tip:hover span {
  display: block;
  transform-origin: 100% 0%;
  -webkit-animation: fadeIn 0.3s ease-in-out;
  animation: fadeIn 0.3s ease-in-out;
}

.help-tip span {
  display: none;
  text-align: left;
  background-color: #1E2021;
  padding: 5px;
  width: 200px;
  position: absolute;
  border-radius: 3px;
  box-shadow: 1px 1px 1px rgba(0, 0, 0, 0.2);
  left: -4px;
  color: #FFF;
  font-size: 13px;
  line-height: 1.4;
}

.help-tip span:before {
  position: absolute;
  content: '';
  width: 0;
  height: 0;
  border: 6px solid transparent;
  border-bottom-color: #1E2021;
  left: 10px;
  top: -12px;
}

.help-tip span:after {
  width: 100%;
  height: 40px;
  content: '';
  position: absolute;
  top: -40px;
  left: 0;
}

<span class="help-tip">
    	<span > This is the inline help tip! </span>
</span>

You can use the title attribute, e.g. if you want to have a Tooltip over a text, just make:

<span title="This is a Tooltip">This is a text</span>

Another similar way to do it by css:

<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>

Pure CSS:

.app-tooltip {
  position: relative;
}

.app-tooltip:before {
  content: attr(data-title);
  background-color: rgba(97, 97, 97, 0.9);
  color: #fff;
  font-size: 12px;
  padding: 10px;
  position: absolute;
  bottom: -50px;
  opacity: 0;
  transition: all 0.4s ease;
  font-weight: 500;
  z-index: 2;
}

.app-tooltip:after {
  content: '';
  position: absolute;
  opacity: 0;
  left: 5px;
  bottom: -16px;
  border-style: solid;
  border-width: 0 10px 10px 10px;
  border-color: transparent transparent rgba(97, 97, 97, 0.9) transparent;
  transition: all 0.4s ease;
}

.app-tooltip:hover:after,
.app-tooltip:hover:before {
  opacity: 1;
}

<div href="#" class="app-tooltip" data-title="Your message here"> Test here</div>

This is my solution for this:

https://gist.github.com/BryanMoslo/808f7acb1dafcd049a1aebbeef8c2755

The element recibes a "tooltip-title" attribute with the tooltip text and it is displayed with CSS on hover, I prefer this solution because I don't have to include the tooltip text as a HTML element!
