Does your website pass the Google mobile-friendly test? If not, you need Web Designer!
Put simply you can create multiple variants - eg desktop, tablet, phone - with shared content (eg text, photos, graphics) but with the ability to freely customize the layout of the variants to suit the target device size. The layout of the variants is entirely in your control, ensuring a quality result for mobiles and tablets. Web Designer export s a single HTML file that can dynamically change from one layout to another depending on the screen size of the viewer.Example (The Vue theme with desktop, tablet and mobile variants)
