How to create next and previous pages button on WordPress?

This is my code so far. I also want to make sure that it checks if a next/previous page exists, if it doesn't, the button should be hidden.

<div class="row" data-component="grid">
   <div class="col-md-6 colView">
      <div class="component_holder">
         <div data-component="button"><a href="#" class="button1 button1--icon-right sm-pull-center">Newer Posts<span class="fa fa-angle-right"></span></a></div>
      </div>
   </div>
   <div class="col-md-6 colView">
      <div class="component_holder">
         <div data-component="button"><a href="#" class="button1 button1--icon-right sm-pull-center">Older Posts<span class="fa fa-angle-right"></span></a></div>
      </div>
   </div>
</div>
