Logo at the middle

Can you post a link to your site?

You can see it at https://www.fanfarefetignymenieres.ch

If will be nice to center the logo both with the sidebar-menu and the top-menu displays…

It looks like you’ve already got some custom CSS in your site. You should delete these lines from your custom CSS plugin:

.caption-image {text-align:center;width:100px;}

.caption-image {float:right;}

And replace them with this:

a.caption-image img {
	margin-left: auto;
	margin-right: auto;
}

It works…
Thanks !
