Help Understanding 15. Linking Fonts II issue

Hi all,

I’m currently doing and I could not figure out why I was doing what the tutorial was telling me, but it would not recognize my link for step 1 of the instructions as the correct answer.

In the Google Fonts page I copied the following details:

<link href=",700&display=swap" rel="stylesheet">

I kept getting the error message that I was wrong, so I read back through the details and the examples and saw that the text I was copying was different to the examples. In the text I was copying it included &display=swap

I’ve removed this &display=swap and now my result is accepted as being correct. So my question is, what does this &display=swap do exactly?
