How to represent inheritance in database?

I'm thinking about how to represent complex structures in a SQLServer database.

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.

However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri

Course Introduction：According to media reports on June 30, the recent divorce case of a post-95s couple has attracted widespread attention in society because in addition to traditional assets, their property dispute also included a Xianyu account.
