How to modify picture size in backend listing

Hello,
How can I modify the picturesize (bigger) in the backend listing for managing the propeties.
Second question: which CSS style is respnsible for the short description in property detail. I want to change the size, but can not find the right entry.
Thanks in advance

Hi Martina,
To increase the width size of picture in Properties listing at Back-end side, please follow these steps:
1. Open file: root > administrator > components > com_osproperty > classes > property.html.php
2. Find and increase value 90px to another number like 120px

To change the font-size of property description at front-end, i advise you to use Inspect Element tool of browser to find the css element source modify css attributes.
Thanks
Dam
