I'm not a great graphic designer or UI designer. I'm developing a plugin that has a popup window on click of a link on webpages. The effect is similar to this one:
But instead of images, like on Fancybox, our content is text possibly mixed with small images.
So you click a link, the popup comes up and hides the background content. I just don't know how big should this popup be and if it should be responsive or not. Meaning, when the window is resized, should the popup box resize with it.
Why would I choose to make a popup window responsive? When should I apply responsive design? What purpose does it serve? (I already have an alternative mobile version, so that can be taken out of the equation)
My popup can be seen here:
