Improve spacing and remove the heading description

Hello! can someone please help me about the following topics: I would like to improve the spacing on the desktop layout- meaning put the content on the text closer together, like for instance on the homepage the part below 'Welcome to Avani' where our criteria are described. There is quite some space between the text, the criteria and the dots. https://avani.online/ Also, if you scroll further down, before and after ''customer information'' there is quite some space. Is that possible? Furthermore, I would like to remove one time the heading H2 word ''description'' on the product page. https://avani.online/product/sweater-gents-green-copy/ Can someone please support?
