    that does not make sense – if a post is in multiple categories, which one do you want to choose as the current one?
    are you aware that the function post_class() already outputs CSS classes related to the single post’s categories?
    https://codex.wordpress.org/Function_Reference/post_class

    to get the category ids of all the post’s categories into the CSS class, try:

    <div class="single-post" id="<?php $categories = get_the_category();
if($categories){
foreach($categories as $category) {
echo  ' category-id-' . $category->term_id;
} ?>">

    what theme are you using?
