Common settings for all codes
Red number - category number
Attention! if any category is hidden from the user, then the codes will be applied to the next one after it!

catright - is the selector for the block following the category name.
You can insert pictures/descriptions BEFORE the title by replacing this selector with catleft

All codes that you see here are inserted in Administration > Custom style
OR you can paste them in Administration> Preferences> HTML-top, but BETWEEN <style> tags:

Код:
<style>
here are your codes
</style>

First of all, you need to insert the code:

#pun #pun-main div.catright {display: block !important;}

It is inserted because many default styles hide catright (or catleft). If you are using Custom Style, it’s best to make sure you don’t have any codes to hide this selector (or find and remove them).

margin-bottom: 5px; /* indentation of descriptions from category text */
display: inline-block;
}
.category h2:hover {height: 145px;} /* category height (AFTER hovering over) */

if the indicator is not needed, you can remove all purple
you can insert an icon-picture instead of the indicator, for this replacebold lines with background-image: url(https://i.imgur.com/SYiogWH.gif);

this code applies to all categories. if necessary, apply to a specific one, replace .category with #pun-category1

after these codes, you can insert a suitable code for the category descriptions.
