fixed up arrow

Code for the widget:

<style>
#scrollup2 {
width: 50px;
height: 48px;
background: #e2c163;
text-align: center;
padding: 10px;
position: fixed;
bottom: 0px;
float: right;
z-index: 9999;
margin-left: 270px;
}
</style>

<a href="#" id="scrollup2" class="scrollup"><i class="fa fa-chevron-up"></i></a>

If you make a arrow in the theme of the site is also good.
