Dear support
I want developed an website for an very good customer. He wants the Web site responsive and want to have it on the following screens: On the desktop (> 1600px), on a Laptop (1200 px), on a tablet (768px), on a smartphone landscape (480px) and on a smartphone (320px).
If I ever get past the purple breakpoint am changing every time the layout and formatting, and should I reset my whole flexgrid control because huge time consuming if you create a Web site of 15 pages.

How can I best make that website responsive and the perfect layout and formatting that you have set up in the smallest breaking point so 320px or should I on that purple.

In other words, I get a different layout in my CSS grid and all CSS formatting settings are then apparently lost.
Is there a possibility to my website on all these screens can give as good as possible, maybe a roadmap or an example how to do that. Maybe a youtube video how to do in site designer.
My website just makes use of flex-flexgrid control containers and containers

Best regards

Stefke, does your very good customer know anything about responsive webdesign? Whether he/she does or does not, you should be able to tell him/her that 'responsive' does not mean a certain screen size for each of the devices you mention. You should tell him/her that it means a 'gliding' size adaption. What if someone has a device which is not 'standardized'? As an example, my laptop is 1920x1080, so 1200px width would look pretty tiny.

Remember, customers are NOT ALWAYS right, they have to be educated!

I agree with the group here.

When I design my websites I do not pre-determine my breakpoints. I will start at mobile size and work my way out fixing the layout and adjusting elements as the screen grows. Quite often I don't add any breakpoints and only use the ones that SD3 provides me.

The idea here is to make it look good on all devices, one site fits all website design. I would not take any demands like you have as this is setting you up to loose.
