Hi Jakob,
I’m afraid you can’t change the name of the navigation with only CSS as this requires few alterations on how WordPress works.
Tom’s provided solution here is split in 2 different codes.
This part is PHP code:
add_filter( 'previous_post_link', function( $output, $format, $link, $post ) {
if ( ! $post ) {
return '';
}
return sprintf(
'<div class="nav-previous"><span class="prev"><a href="%1$s" title="%2$s">Previous</a></span></div>',
get_permalink( $post ),
$post->post_title
);
}, 10, 4 );
Here’s How to add PHP
This part is CSS code:
.post-navigation {
display: flex;
}
.nav-previous {
margin-right: auto;
}
.nav-next .next:before {
display: none;
}
.nav-next .next:after {
font-family: GeneratePress;
content: "\f105";
text-decoration: inherit;
position: relative;
margin-left: .6em;
width: 13px;
text-align: center;
display: inline-block;
-moz-osx-font-smoothing: grayscale;
-webkit-font-smoothing: antialiased;
font-style: normal;
font-variant: normal;
text-rendering: auto;
line-height: 1;
speak: none;
}
