    Hi, thank you for a great tool.

I found that there's an invalid style definition `margin-left` in the `.centered` class in `style.css` file. In the file is written `margin-left: left`, while it's an undefined value according to [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/CSS/margin-left). Could you please. to fix the style to make it error-free. 

I don't know what value was meant to be there: `0px`, `auto` or maybe someone just misread documentation, as `left` is defined, but not for this property and not for this usage.
