Move Logo left from Page Title

Dear Community, I would like my logo to be centered to the height of the logo and to be placed left from the page title independently of screen size. Currently, it is right from the title and the title is aligned with the upper edge of the logo. Also, its position changes with the screen size. One could also remove the "search box", I do not need it and then I'd have more space. I guess Custom CSS is needed here...? Thanks for any hints on how to do that.
