In this post I am going to show to how to create a circular Navigation using css3 transform effect. By following some simple logic and steps you can create a very good looking circular Navigation.
Like I am going to mention here something for example we are using some basic math calculation to create css transform to create these styles.
HTML:-
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
<div class="component"> <!-- Start Nav Structure --> <button class="cn-button" id="cn-button">+</button> <div class="cn-wrapper" id="cn-wrapper"> <ul> <li><a href="#"><span class="icon-picture"></span></a></li> <li><a href="#"><span class="icon-headphones"></span></a></li> <li><a href="#"><span class="icon-home"></span></a></li> <li><a href="#"><span class="icon-facetime-video"></span></a></li> <li><a href="#"><span class="icon-envelope-alt"></span></a></li> </ul> </div> <div id="cn-overlay" class="cn-overlay"></div> <!-- End Nav Structure --> </div> |
