I’m hitting these keys out of habit. They are Cmd + Alt + U in Chrome on a Mac. Ctrl + U in Firefox on a Windows-machine. This is kind of a hobby to me. I’m talking about viewing the source.
It seems to me that we are not viewing the source of the web sites we are working on enough. So I now urge everyone to at least start checking the most common page types before you put things into production. Check each element and make sure you know what it’s doing and why it’s there. If you are not sure ask your colleagues.
Let us stop making these stupid mistakes!
