Remove dashed line

Hello,
I have removed the Home Page Heading & Subheading using CSS codes:

.home-content .page_info {
display: none;
}
.page_info_wrapper p {
display: none;
}
But, there is still a dashed line appearing. I would like to remove the dashed line and decrease the space below the header and the "Latest Blogs" section.
My website is www.optionincomeblog.com
Thank you for your help!

Code:

display: none;
}
