Tribute Page:Your #image should be centered within its parent

I have tried various ways to center my image but none have worked so far. I’m not sure why what I have in my CSS #image selector is not okay.

  **Your code so far**

Challenge: Build a Tribute Page

Link to the challenge:

Hello. Be aware I’m not experienced much.
However

you have property

Take a look at MDN:

I believe to use this property, you need flex container.

That means parent element for image should be flex container.

Aslo I am not sure about:

Some width-related props are in pixels, some in percent. But that’s for discussion. I would personally try to avoid this.
EDIT. Or maybe it’s all good about width, I just don’t think if you have width 100%, you don’t need max-width 100%

EDIT2. Also I should ask, for what purpose did you add padding to your #img

On this forum it is not considered best practice to give direct solutions, and I just say:
when I did this project, i ended up with 1 or 2 properties for #img selector. To center it you don’t necesariily need complex styling.

Figured it out. Thank you!
