Font size and padding improvement

Hi,

I am new to php and coding so pardon me for a small question.

I am developing- https://badastock.com/product-category/cotton-fabric/

Here if you observe, the fond size and the looks of the filters is not apt as if shown in the video tutorial-https://www.youtube.com/watch?v=jZPtdWgAxKk

Pls suggest what needs to be done to get the looks of the filters right.

Thanks.
