Can I create a popup that has "Are you 21+ or older?"

We have been asked for a popup that has a question with  [ Yes ] and [ No ] buttons

In this example the question could be: "Are you 21+ or older?"

• Yes closes the popup. 
• No loads to another URL

In HollerBox 

Select the template: PopUp with Yes/No
Select the position of the popup ( Top Left, Top Center, Top Right, Center Left, Center Center, Center Right, Bottom Left, Bottom Center, Bottom Right )
Enter the content: In our example we'll place our question, Are you 21+ or older?
Overlay leave as default
On the buttons, we'll reverse the buttons, first No!, second Yes by changing the Button Text.

For the Yes, select "Redirect to page and enter the URL 

For the No, select "Close the popup.

Here is the result of our example
