Remove left column (meta information)

You’ll have to play around with this code to get exactly what you want but use this: (add it to your additional css in customize)

@media screen and (min-width: 61.5625em) {
body:not(.search-results) article:not(.type-page) .entry-footer
{
float: none;
margin-top: 1.5em;
width: 100%;
}
.single .byline, .full-size-link,
body.group-blog:not(.search-results) .byline,
body:not(.search-results) .entry-format,
body:not(.search-results) .cat-links,
body:not(.search-results) .tags-links,
body:not(.search-results) article:not(.sticky) .posted-on,
body:not(.search-results) article:not(.type-page) .comments-link,
body:not(.search-results) article:not(.type-page) .entry-footer .edit-link
{
display: inline;
}
body:not(.search-results) article:not(.type-page) .entry-footer > span:not(:last-child):after
{
display: inline;
}
body:not(.search-results) article:not(.type-page) .entry-content
{
float: none;
width: 100%;
}
body:not(.search-results) article:not(.type-page) .entry-footer .avatar
{
display: inline;
margin: auto 0.3em 1em auto;
width: 27px;
}

WordPress says there is an error in the code, however it works, thanks!!
But it displays the meta information at the bottom of the page, I’d like it to be at the top, if anyone knows how to do it…

I have been able to move the meta information at the top of the page, before the title, by modifying the php code of Twenty Sixteen. I describe the process here:
https://www.justthink.it/articles/remove-left-column-twenty-sixteen/
You must search for twentysixteen_entry_meta in the file content-single.php inside template-parts and move it
I think it’s not possible to move the meta information to the top unless you modify the php code, because the meta information is part of the footer.
My solution is not fully clean because I used the css of the footer in the header, but it works for now
