The gap between experts and porters - the power of learning methods

Learning is a commonplace issue, especially in today's context where Internet technology is iterating faster and faster and competition pressure is increasing. Learning has become an essential skill for "natural selection and avoiding elimination" in the social ecology. Although learning requires methodology, there is no set of learning methods that suits everyone.

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
