Alternative to copy or download generated QR (vue-qrcode) code using VueJs

I'm using the plugin "vue-qrcode" to generate a QR code for users to create a QR code for their public profile link so they can share it on their business card. The idea now is to give the user the possibility to download the QR code through a button and copy the QR code to the clipboard through another button to make it easier to send via email (especially for smartphone users). The problem is: I don't know how to download or copy the QR code. Does anyone know how to copy or download the QR code? Currently I'm using "vue-clipboard2" to copy links etc but can't seem to copy images.

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
