Context: I had done the creative for a web application and sent it to the front end developer to take care of. He took the initiative about 1 aspect that I'm unsure about how it effects users.
I have a series of buttons with icons and it already has an obvious hover state of inverted colour. In my design, the icons stay the same size. The FED decided to make the icons grow on hover.
Has anyone done any research or have any thoughts on this? Is it good or bad?
It doesn't re-arrange any elements around it when I mouse over it..
The icons are for visual clarity of the command and are not thumbnails of any images or anything.
EDIT: The application is designed to be responsive for desktop and is in planning stage for mobile in future. Hence, hover is still important to have here for this first iteration.
