Tooltip with a triangle [duplicate]

问题

I have created a jsFiddle for this question.

a.tip {
    position: relative;
}

a.tip span {
    display: none;
    position: absolute;
    top: -5px;
    left: 60px;
    width: 125px;
    padding: 5px;
    z-index: 100;
    background: #000;
    color: #fff;
    -moz-border-radius: 5px; /* this works only in camino/firefox */
    -webkit-border-radius: 5px; /* this is just for Safari */
}

a:hover.tip {
    font-size: 99%; /* this is just for IE */
}

a:hover.tip span {
    display: block;
}

<center><a href="http://google.com/" class="tip">Link!<span>Hi its me!</span></a></center>

Basically I have a tooltip on my site, and it appears to the right of my link. But on the left hand side of the black box I would like a triangle attached to the box pointing to the link, is it possible to do this using only CSS? just like this but to the left

回答1:

You can do it with CSS, by using the css triangle trick

a.tip span:before{
    content:'';
    display:block;
    width:0;
    height:0;
    position:absolute;

    border-top: 8px solid transparent;
    border-bottom: 8px solid transparent;
    border-right:8px solid black;
    left:-8px;

    top:7px;
}

I developed CSStooltip.com to make tooltips with triangle in CSS only.

Example :

span.tooltip:after {
      content: "";
      position: absolute;
      width: 0;
      height: 0;
      border-width: 10px;
      border-style: solid;
      border-color: transparent #FFFFFF transparent transparent;
      top: 11px;
      left: -24px;
}

Try this: http://ecoconsulting.co.uk/examples/css-tooltip/

It explains the problems and fixes the issues, and allows for an arrow and tooltip with a border.

You can put both color and image as background and also set its position . In the code below replace the image in the url tag with one that has the triangle you want.

a.tip span {
    display: none;
    position: absolute;
    top: -5px;
    left: 60px;
    width: 125px;
    padding: 5px;
    z-index: 100;
    background: #000 url("http://www.triangle-fr.com/img/tooltip.png");
    color: #fff;
    -moz-border-radius: 5px; /* this works only in camino/firefox */
    -webkit-border-radius: 5px; /* this is just for Safari */
}
