Moving Site Logo to the Left

I do not have experience in creating a website and this is my first one so please bear with me.

My site logo is above my header.

I am trying to move my site logo to the left of a “centered” header from a pre-selected them called “Go” on WordPress but I can’t seem to figure this out. Every time I watch a youtube tutorial and add “padding-left” pixels, it moves the site logo to the right (perhaps because my site logo position’s default is fixed in the center?)

Please help. Thank you.
