How to increase the image of products in category section using the css (solved)

[Grigorii]

Hello everyone.
The version of Virtuemart is 3.2.6 and Joomla 3.8.2
We configured the Virtuemart to show 3 products in the row. It is completely good for us. Look like this

We are no using special templates for Virtuemart. Everithing only build in.
And original images we uploaded to shop have size 800x600 px;
But the images are too small. So the questions:
1. How to increase the images, which of css stile we should change for it? May be there is other way (for example in shopping configuration)?
2. And the images should not be degraded, fuzzyed?
Thank you ahead.

Yeah, after 30 minutes of brainstorming we have found the decision.
Tool - Templates - Thumbnail Image Height - must be set as you wish!
