You can't use foreach inside a echo. To achieve what you are trying you can use implode function, it concatenates the values of an array on a string.
echo "<div class='transition " .implode(' ', $category_slugs). "' data-category='transition'> " ?>

try this code
<div class="transition <?php foreach($category_slugs as $slug){echo $slug . ' ';} ?>" data-category="transition">
The concatenation operator ('.'), which returns the concatenation of its right and left arguments.
from php manual
But this code not a string.
foreach($category_slugs as $slug){echo $slug;echo ' ';}
So you will get a error.
This manual may help you Escaping from HTML.
Sorry for my bad english, I hope it will help you.

try this
$category_slugs =array('a','b','c');
foreach($category_slugs as $slug){
echo "<div class='transition ".$slug.' '."' data-category='transition'></div> " ;

thanks . I need a div tag and multi class . your code is echo multi div tag
Wrap <div> in a for loop, like so
<?php
$slug_string = "";
foreach($category_slugs as $slug){
$slug_string .= $slug_string." ";
}
echo "<div class='transition ".$slug_string."' data-category='transition'> ";
?>
