page single conditional

Your first code sample didn’t work because the elseif had no condition. elseif is a concatenation of else and if:

if ( something ) {

} elseif ( something else ) {

} else {

}

Or

<?php if ( something ): ?>

<?php elseif ( something else ): ?>

<?php else: ?>

<?php endif; ?>

Also, if you want a front page that’s different from your other pages, look at the front-page.php template.
