I'm developing homepages to myself. The pages looks good on my laptop but I would like to see if it looks good also in my mobile. Can I test how the sites looks in mobile without publishing the site first in the Internet? My laptop has Ubuntu 20.04.
Firefox and Chromium have Responsive Design Mode:
(For Chromium accessible only in Developer Tools, in Firefox globally)
IF YOU ARE WILLING TO USE WINE,
Try the chrome based Blisk (blisk.io). It's great for web design as you can preview for tons of common mobile platforms.
