How to remove left and right arrows that appear next to “About The Author”

.post-navigation {
    display: none !important;
}

Thanks, this removed the arrow area.
But now there is just a blank square space net to the ‘About the author’, in place of the arrow section. And it looks weird.

Is it possible to remove that space entirely and only have the Author section?

.about-the-author { width: 100% important; }

I’m sorry but this change has no affect.

put ! in front of important

Thank you, you are a gem ??
