Understanding UA Strings
What is a User Agent?
It is a text string that your browser sends to every website you visit. It acts as an 'ID card' that tell the server what technology your device supports.
Debugging Mobile Layouts
If a user reports a bug on a specific device, ask for their User Agent. You can then use this parser to see exactly which OS and browser they were using.
