Pure CSS and HTML QR Code Website

I think the main problem I faced was with the text alignment or just general alignment. First of all, I made the white box a flexbox column and put the image and another div called texts in the column. The problem I had was, after I aligned the actual image, I wasn't sure how to make sure that the text takes up the rest of the space under the QR code. I tried to use a display grid on the texts div, but then the texts had a lot of space between each other due to auto margin, which I couldn't get rid of. I gave the texts div a pre-set margin of 5px and removed flex-grow and somehow the texts just got fixed. Overall, alignment was a big issue.
