Adjust colums so middle one is wider

I think im being a bit half witted.
Im creating the header of a website
The header will be in the middle colum of 3

But how do I create the middle colum wider than the left and right one?

The header is too squished on ipad so I need to make its space avail wider

Good evening @Domino

That is done through the use of the Custom Columns feature of the Columns stack. Head over to the Foundry Tutorials page and watch the “Using Columns” tutorial video. It talks about how to make use of this feature and more and will get you headed down the right path.
