I've attached the file I created based on that blog and links to developer tools on Facebook and Google Plus.
I don't have a website set up, so am just opening the HTML file in Internet Explorer.
The Twitter and Reddit buttons work, bringing up login pages for those sites, but the Facebook and Google Plus buttons don't work.
1. Am I doing something wrong in the code?
2. Would those buttons work if they were on a real website rather than just my test HTML file?
3. Why do the Twitter and Reddit buttons work when the Facebook and Google Plus buttons don't? social-netowrk-button.html
