Website Testing Tools

Hello ,
I wanted to thank you for pointing me to Google’s Mobile-Friendly Test tool on your page here: christianoliff.com/blog/website-testing-tools However, after playing around with it, I got frustrated by the fact that it doesn’t let you interact with the page, and only gives you a picture of the upper part of the page. So I went ahead and searched for a better tool and found this one – https://www.websiteplanet.com/webtools/responsive-checker/, that doesn’t just show you a picture of the page, but actually lets you scroll up and down and even sideways) - that’s what I guess we all really need. Yes, I was amazed too that it’s better than Google’s 😊 So I thought that since you got me to Google’s tool first, I would return the favor, so you can share that improved tool with other users on your page. Hope I helped.
