Ok, I will try,
On a product page with multiple images, there is two divs like that
<div id="hikashop_main_image_div">
<div id="hikashop_small_image_div">
But if you got characteristics, these divs will be called after ajax request:
<div id="hikashop_main_image_div_4">
<div id="hikashop_small_image_div_4">
or _div_5,etc...
So, what I suggest is to create a generic class
<div id="hikashop_main_image_div" class="hikashop_main_image_div">
<div id="hikashop_small_image_div" class="hikashop_small_image_div">
and when the name of the div will change, we will still retain the style of the class for styling the element...
Is it clearer ?
