Question
I would like to have a little triangle underneath the the text that points up when the user hovers over the different tabs. Here is a bit of code I'm working with.
* {
margin: 0;
padding: 0;
list-style: none;
}
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 11px;
margin: 10px;
}
.tab {
width: 100%;
padding: 5px;
background: #fff;
color: #000;
cursor: pointer;
font-weight: bold;
border-bottom: 1px solid black;
position: relative;
}
.tab:hover {
background: #a0a0a0;
}
.tab:hover span {
display: block;
}
.tab_child {
padding: 15px;
background: #fff;
}
.selected {
background: #a0a0a0;
}
.contain * {
float: left;
width: 100px;
}
span.triangle {
background-image: url("http://www.inner.org/torah_and_science/mathematics/images/triangle.gif");
background-repeat: none;
display: none;
height: 14px;
width: 16px;
position: absolute;
top: 25px;
left: 25%;
}
<div class="contain">
<div id="one" class="tab selected">Link1</div>
<div id="two" class="tab">Link2</div>
<div id="three" class="tab">Link3</div>
<div id="four" class="tab">Link4</div>
<div id="five" class="tab">Link5</div>
</div>
Solution
I think this is probably what you're looking for:
Also, please use semantic markup:
- If your using HTML5 wrap your navigation in
<nav>
tags. - Your links (if they really are going to be links) should be
<a>
elements. - For a list of links like you have it is advised to use a list (
<ul>
&<li>
).
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 11px;
}
nav ul {
margin: 0;
padding: 0;
list-style: none;
}
nav li {
float: left;
width: 20%;
}
nav a {
display: block;
padding: 5px;
border-bottom: 1px solid black;
background: #fff;
color: #000;
font-weight: bold;
position: relative;
}
nav a:hover,
.active {
background: #bbb;
}
nav a:hover:after {
content: "";
display: block;
border: 12px solid #bbb;
border-bottom-color: #000;
position: absolute;
bottom: 0px;
left: 50%;
margin-left: -12px;
}
<nav>
<ul>
<li><a href="#" class="active">Link1</a></li>
<li><a href="#">Link2</a></li>
<li><a href="#">Link3</a></li>
<li><a href="#">Link4</a></li>
<li><a href="#">Link5</a></li>
</ul>
</nav>
OTHER TIPS
Here is a modification to your jsfiddle:
I've added a <span class="arrow"></span>
to contain the triangles in the HTML:
<div class="tab_container">
<div id="test1-header" class="accordion_headings header_highlight" >Home<span class="arrow"></span></div>
<div id="test2-header" class="accordion_headings" >About<span class="arrow"></span></div>
<div id="test3-header" class="accordion_headings" >Work<span class="arrow"></span></div>
<div id="test4-header" class="accordion_headings" >Social<span class="arrow"></span></div>
<div id="test5-header" class="accordion_headings" >Contact<span class="arrow"></span></div>
</div>
Here are the changes made to your menu which reduce the size of the triangle and position them at the bottom center of each menu item when hovered over: CSS:
/*
.accordion_headings:hover{
background:#00CCFF;
width: 0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
border-bottom: 5px solid red;
}
*/
.accordion_headings{
position:relative;
}
.accordion_headings .arrow{
display:none;
}
.accordion_headings:hover .arrow{
width: 0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
border-bottom: 5px solid red;
display:block;
position:absolute;
bottom:0;
left:49%;
}
