// How to:
// 1. Open the Firebase Analytics Dashboard
// 2. Scroll to bottom, where you see the "Users by Device model" widget

// 4. Above the table shown in the new page, click on the “Device model” drop down menu and select “OS with Version”
// 5. Make sure to select “OS with version” and not “OS Version”
// 6. On the top right corner of the page, click on the “Share this report” icon (next to the date)
// 7. Click “Download file” on the new side bar, then “Download CSV"

58 bytes of css to look great nearly everywhere

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

NoNewPrivileges=yes
PrivateTmp=yes
PrivateDevices=yes
DevicePolicy=closed
