Multiple word-words

[lopsided]

I found that when my tags contained multiple words (ie, "World Cup") then I kept getting overlapping words. I tracked this down to the js span.offsetWidth which doesn't give the correct value. The way to fix this is to add this to the css:

.tangcloud span {
    white-space: pre;
}

Happy to submit a PR if you want to add this to the readme and/or example?

Good catch! If you'll put in a PR to add this to the readme I'll approve it.
