translation question, 'previous'and 'next'

Hi there,

in Appearance > Elements edit the Custom Post Navigation element.
Look for the two lines containing those words and update accordingly.

They are:

<div class="post-nav"><?php _e( 'Previous', 'generatepress' ); ?></div>

and

<div class="post-nav"><?php _e( 'Next', 'generatepress' ); ?></div>

Thanks, I changed the RBG coloro in this location to change background color behind words previous and next.....But that does not work,,,do you know how?

The label colors are set in Customizer > Additional CSS:

.post-nav {
    padding: 6px 12px;
    border-radius: 3px;
    font-size: 0.7em;
    text-transform: uppercase;
    background-color: #ff1956;
    color: #fff !important;
}
