Convert numbers to time in Google Spreadsheet

I'm trying to build an automated GoogleSheets spreadsheet where I can enter the date, start time, lunch time, end time, number of hours worked per day, and finally sum up the number of hours worked for a month.

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
