如何将具有不同屏幕尺寸的div居中？

Question

I have a set of <div> s lineup horizontally in my container and I'm looking to center my Outer-Container <div> class with the rest of the code on my web page (Squarespace).

I've made a CodePen re-creating the page and I still can't seem to center my outer-container within the Main-content section with varying screen sizes.

Any help is greatly appreciated!

Answer 1

I visited your web page and inspected the page source. It seems like the padding: 100px in .outer-container is breaking the display. You have to add negative left margin like margin-left: -100px to reposition your div .

Anyway, you may want to refactor your code and move the image to a bigger parent div then apply the padding there.
