Need space between two buttons on blog - html

Question

I need help to create space between two buttons on my blog, one for previous post, one for next. Both buttons appear one next to another, i need to be in the right and left corner. This is the code for them:
<?php
$prev_post = get_previous_post();
if (!empty( $prev_post )): ?>
<a class="post-nav-prev" title="<?php _e('Previous post:', 'baskerville'); echo ' ' . esc_attr( get_the_title($prev_post) ); ?>" href="<?php echo get_permalink( $prev_post->ID ); ?>"><?php _e('Previous post', 'baskerville'); ?></a>
<?php endif; ?>
<?php
$next_post = get_next_post();
if (!empty( $next_post )): ?>
<a class="post-nav-next" title="<?php _e('Next post:', 'baskerville') ; echo ' ' . esc_attr( get_the_title($next_post) ); ?>" href="<?php echo get_permalink( $next_post->ID ); ?>"><?php _e('Next post', 'baskerville'); ?></a>
<?php endif; ?>
<?php edit_post_link( __('Edit post', 'baskerville')); ?>
<div class="clear"></div>

I honestly tried to run your code snippet locally, but just couldn't get it to work so I will do my best and help you achieve what you want.
But before I get started, make sure you don't post PHP snippets in a post that has nothing to do with PHP. If you were to only post the HTML code, it would have made things much easier.
So I see you have two a elements which you are using as buttons. You don't want them next to each other but "in the right and left corner" Although I'm not sure whether you mean the corners of the page or the corners of where those buttons might or might not be, here is how I would tackle this problem.
#navigationControls{
width:300px;
height:20px;
}
<div id="navigationControls">
<a class="post-nav-prev" title="test">Previous</a>
<a class="post-nav-next" style="float:right" title="test">Next</a>
</div>
By putting them in a container with a defined width, we can float the next button to the right of the container. You can modify the containers width to how big you want it to be.
Please let me know if my answer got you in the right direction and if you need any help!
