I would like to show you my new project - built with Vue. It’s an online app for website wireframing. I tried to follow the process of coding - when you add a div to the code, it is there, regardless of screen size, but you can change it’s size with css. My tool works the same way: when you draw something, it exists, and you can switch to a different screen size and change it’s dimensions (or hide it if you don’t need it on this screen size)
My app is here: Wirenook
Please note it’s a beta version and might be unstable.
I will appreciate your feedback!
