With a power of css3 animation it is possible to implement css3 floating button only with css and without the use of javascript or jquery library. This tutorial explains 3 different versions of css3 floating button.

Our css3 floating button is fully responsive and works great in smaller devices like mobile and tablets.

Make sure to add below tag to your page head to scale buttons perfectly in mobile devices.

<meta name="viewport" content="width=device-width, initial-scale=1.0">

For icons i used FontAwesome icon font. In below examples, you like to see <i> tag with some default classes like fa,fa-plus etc. which tells FontAwesome to load specified icon.

For example: the class name fa-plus tells font awesome to load google plus icon into <i> tag.

If you don’t know what icon font is? then you can refer this article using fontawesome icons for all icons and their usage
