Can I put bothhrefandidin the same<a>tag? Would I want to for any reason?
A1:
You can, and it might save you some typing if you have a named anchor point and a link right next to each other. It's generally better, however, to use <a href> and <a id> separately to avoid confusion because they play very different roles in an HTML document.
Q2:
What happens if I accidentally spell the name of an anchor wrong or forget to put the # in front of it?
A2:
If you link to an anchor name that doesn't exist within a page or misspell the anchor name, the link goes to the top of that page.
Q3:
What if I use a different company to handle my email than handles my web pages? Will my email links still work?
A3:
Yes. You can put any email address on the Internet into a link, and it will work fine. The only situation in which email links won't work is when the person who clicks the link doesn't have an email program set up on his computer, and therefore isn't capable of sending email.
