My publish website is not recognised by the responsive checker sites

Hello Webflowers,

I was wondering why the url of a published webflow website is not acceptable/recognisable by the dozens of ‘‘check your responsiveness’’ websites.

A few examples —> http://responsiv.eu/
http://ami.responsivedesign.is/
https://www.responsinator.com/

It is probably a simple answer but the reason i am asking is I have an old kinda thin tablet that I test my responsive design on tablet portrait view and the elements in it appear significantly smaller than what the tablet portrait view shows on webflow.

I understand that to honestly check the responsiveness of a website it must be done on real devices but it would be helpful if i could also check the website on the various sites i explain above.

Thank you i advance!

What’s the URL of your site?

http://gravidoo.webflow.io/

it’s literally in the beginning and i am just looking to making every section responsive before i start on the next one.

Thank you for your reply!
