I would like to share with you a reliable website that you can test the responsive functionality of your site on other platforms such as mobile, tablet, desktop and laptop. Here’s the link: http://responsivetest.net/
All you need to do is to simply type the website address on the text field located at the top,
Then, choose what platform you want to check your website: mobile, tablet, desktop or laptop.
From there, you can check if there are sections of your website that are not yet mobile responsive or having issues on other canvas. The contents like text and photos must automatically fit in whatever canvas you choose. That’s it and enjoy testing your site!
