i am having a few issues with this setup. Please help!

1. How do I link the Contact Pop Up Form in the Home Bottom E position to a Contact Us Menu Item?
2. I created an external URL link to a Menu Item by going to Menus > Main Menu > (created a Menu Item) External Site > Menu Item Type > URL and input the URL into the Link box. However, when you click on the Menu Item, it takes you to the site + the URL.
Example: Link URL is www.hiddenacresweddings.com
Site is: www.theloft109.com
When you click on the Menu Item it should take you to www.hiddenacresweddings.com but instead takes you to www.theloft109.com/hiddenacresweddings.com
3. In the Quickstart Template, there is a secion in Position Home Bottom E. How do I change the background image?

Thank you in advance for your help!

I have figured out #1 above but still need help with #2 and #3 please!

3.) Home Bottom E Background can be changed in the theme settings > Backgrounds
2.) Its a simple link with a popup like this

<a class="uk-button" data-uk-lightbox="" data-lightbox-type="iframe" href="your url to your contact?tmpl=component">Contact Us</a>

Thank you for the response.

Is there any way to make the header image and logo larger on the mobile version? Can a different module position be used for that?

Thanks!

Your #2 answer was to my #1 question. I need #2 answered please.

2.) Depends on your external link question
