Quick View, fast and sticky add to cart

Hi Hana,

You'll need to find a plugin which does this.

Is it possible to do it by CSS code?

Hi there,

no it cannot be done with CSS.
CSS is purely for styling HTML. It cannot create HTML or interactive layouts.
You will need a dedicated plugin if you Google "Woocommerce Quick View Plugin" you will find many including the official one:

Thank you my dear :)

You're welcome
