Back to top
Back to top is a navigation button that allows users to quickly revert back to the top of a particular web page. This element is shown in the bottom right corner of the page or mobile screen. The element only appears when the user scrolls a certain distance down the web page.
Back to top buttons are necessary for web pages with continuous scrolling, or a page that includes a long amount of content. A good guideline is to include a Back to top button for any web page that is longer than 4 screens.
Back to top buttons are a custom component built for Aurora. Back to top buttons include a web and a mobile version. Use the class
.btn-backtotop to create the button, the
.mobile class can be added to create the mobile version. Note that the mobile version will require an icon.
In the mobile version, be sure to use the
.sr-only class to provide context for the button.
Back to top
<a href="#main-content" class="btn btn-backtotop"><i class="fa fa-arrow-up icon"></i>Back to top</a> <a href="#main-content" class="btn btn-backtotop mobile"><i class="fa fa-arrow-up icon" aria-hidden="true"></i><span class="sr-only">Back to top</span></a>
This button should always be labelled Back to top since this is the most descriptive and expected label for the function.
