To center your container, you can use either of these reliable methods:
Using auto margin:
Select your container in the Style panel and click the horizontally center icon next to Spacing. This will apply auto margins to both sides of your container.
Using flexbox:
Select the parent element, set the display to flex in the Style panel, then click the center cell of the align box. This method is particularly effective for maintaining center alignment across different screen sizes.
