How to remove "Newer Posts" and "Older Posts" from blog in Blogger

To totally remove these links from the blog posts, you just add some new CSS rules to your template in the usual way.

To remove "Older Posts" add:
#blog-pager-older-link {
float: right;
}

To remove "Newer Posts" add:
#blog-pager-older-link {
float: right;
}

Or to remove both of them and the "Home" link that appears in between them, add:
#blog-pager {
display: none;
}
