Gradient effect of CSS display properties

I'm currently designing a CSS "super dropdown" - basically a regular pure CSS dropdown, but with different types of content in it. Currently, it seems that CSS3 transition effects do not apply to the "display" property, that is, there is no way to transition from display:none to display:block (or any combination).

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
