While browsing the site, I noticed that the navigation menu at the top has a unique feature - a small arrow that points upward for the currently selected section (Home, Learn, Download,...). I tried to figure out how they implemented it, but I couldn't find any clues. The resource didn't show up in Chrome's Resources window, and inspecting the elements didn't reveal any background image or JS interceptor. It's like a mystery wrapped in an enigma! :)
Here is the code snippet in HTML:
<ul id="menu">
<li class="selected">
<a href="/">Home</a><span>></span>
</li>
...
The following CSS code creates a unique visual effect:
#menu .selected a:after {
content: " .";
display: block;
text-indent: -99em;
border-bottom: 0.8em solid #8adc92;
border-left: 0.8em solid transparent;
border-right: 0.8em solid transparent;
border-top: none;
height: 0px;
margin-left: -.8em;
margin-right: auto;
margin-top: 14px;
position: absolute;
left: 50%;
width: 1px;
}
This technique is known as CSS arrows, and there are plenty of resources online to learn more about it.
(EDIT: @jeroen shared a helpful resource).
Upon examination, it appears that a CSS arrow was utilized in this instance. For further details, visit this resource.
Check out the live demonstration by following the link below:
.container{
background: blue;
color: #FFF;
width: 150px;
height: 150px;
position:relative;
}
.arrow-down {
border-left: 15px solid transparent;
border-right: 15px solid transparent;
border-top: 15px solid white;
position: absolute;
top: 0px;
margin-left: -15px;
left:50%;
}
