How to remove Featured image in post

Hi, Can someone told me how to remove featured image in post. I posted 4 post and linked to Category Slider, and when I clicked on Slider title, then post open with featured image which is in slider. I want to like this image does not apear in post, only in slider. Or how could I block opening posts in slider category when I click on them in slider? Greetings!

Hi @srky,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS

body.single img.single-featured.wp-post-image {
    display: none;

Best Regards,
