What are the ways of checking responsive website?

[eaglehopes]

I did instructions in "responsive webpages(RW)"( https://www.w3schools.com/html/html_responsive.asp ) and checked my webpage in https://www.w3schools.com/howto/howto_css_devices.asp .

Thanks Barand, I used Firefox too ,but I could not fine "Responsive Design Mode" in "More Tools", but I can solve that problem. 👍 

Edit : I found it : they hide it under "Developer Tools" ( reference page  : https://firefox-source-docs.mozilla.org/devtools-user/responsive_design_mode/).

Once you get to the other side of testing responsiveness and need to test for many different screen ratios, browsers and devices, tools like BrowserStack etc. can be incredibly helpful Edited October 2, 2022 by loquaci
