Customise logo – Header

Hi,

I am writing to you as I’m trying to customise the logo of my website (= change the logo position so that it appears on the LEFT of the header title/slogan, and not above where it currently is)… is there anybody who knwons how to do it?

Besides, I can’t customise the position of the footer neither (I’ve tried by changing the HTML code in the parent theme through a FTP – Filezilla, but apparently it says it’s already center-aligned but it doesn’t appear so)

Thanks you in advance!!
