Why doesn't VS Code limit each line to a maximum of 80 characters when saving?

I installed the Prettier extension and set the max line width to 80. I also set it up to format on save. When I save the file I'm working on, I find that the comments are still very long. The extension should shorten it to the maximum 80 character width, but it doesn't do that. Do I need to use other settings? Or maybe there is a better extension than Prettier? I just want to use any formatting tool that can eliminate the 200+ errors I get when deploying my TypeScript cloud functions.

Tips to improve WooCommerce member query speed: Optimize MySQL index

I have a WooCommerce membership based website using the Teams for WooCommerce membership extension. Despite having a huge user base (>70,000 users), it performs very well 95% of the time.

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

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
