V1.0.0/2149

why don't create function for this one po so that it will not be repeated?

something like
```
function createOverlarDiv($display, $color = '') {
     return '<div class="book-overlay show-title '.$color.'"><br><h6>'.$display.'</h6></div>';
}
```

then you can just use like this
```
                $book_overlay = createOverlayDiv($book['book_author']?$book['book_author']:'no author', $color);

```
