You can’t just delete parts of the .css because you are going to lose the changes after update.
I was looking for exactly the same and since I didn’t find the child theme code to move the meta from the left-sidebar to the bottom (as it is automatically displayed when you lower the width of the browser window below 985 px) I made it myself.
Bear in mind I am not WP developer so this code might not be ‘by the book’, however – it works. You have to make the child theme folder and put the code in some .css file and then activate the child theme. After that, the meta data will be displayed below the posts, even if the screen width is more than 985 px and the post width will be 100%. The code overrides only the settings when the screen width > 985 px. I’ve commented out the original settings so it can be easily seen what is changed. I didn’t check if the code works when there isn’t the right sidebar. Here’s the code:
‘/*

Description: Meta below instead on the left even on screens wider than 985 px

@import url(“../twentysixteen/style.css”);
/**
